Ukraine (/juːˈkreɪn/ yew-krayn; Ukrainian: Україна, transliterated: Ukrayina, [ukrɑˈjinɑ]; Russian: Украи́на; Crimean Tatar: Ukraina) is a country in Eastern Europe. It has an area of 603,628 km², making it the second largest contiguous country on the European continent, after Russia. Ukraine borders the Russian Federation to the east and northeast, Belarus to the northwest, Poland, Slovakia and Hungary to the west, Romania and Moldova to the southwest, and the Black Sea and Sea of Azov to the south and southeast, respectively.

Established by the Varangians in the 9th century, the medieval state of Kievan Rus', the first East Slavic state, emerged as a powerful nation in the Middle Ages until it disintegrated in the 12th century. By the middle of the 14th century, Ukrainian territories were under the rule of three external powers—the Golden Horde, the Grand Duchy of Lithuania, and the Kingdom of Poland. After the Great Northern War (1700–1721) Ukraine was divided between a number of regional powers and, by the 19th century, the largest part of Ukraine was integrated into the Russian Empire with the rest under Austro-Hungarian control. A chaotic period of incessant warfare ensued, with several attempts at independence from 1917 to 1921, following World War I and the Russian Civil War. Ukraine emerged from this fighting on December 30, 1922 as one of the founding republics of the Soviet Union. The Ukrainian Soviet Socialist Republic's territory was enlarged westward shortly before and after World War II, and southwards in 1954 with the Crimea transfer. In 1945, the Ukrainian SSR became one of the founding members of the United Nations.

Ukraine became independent again when the Soviet Union dissolved in 1991. This dissolution started a period of transition to a market economy, in which Ukraine was stricken with an eight-year recession. Since then, however, the economy experienced a high increase in GDP growth. Ukraine was caught up in the worldwide economic crisis in 2008 and the economy plunged. GDP fell 20% from spring 2008 to spring 2009, then leveled off as analysts compared the magnitude of the downturn to the worst years of economic depression during the early 1990s.

Ukraine is a unitary state composed of 24 oblasts (provinces), one autonomous republic (Crimea), and two cities with special status: Kiev, its capital and largest city, and Sevastopol, which houses the Russian Black Sea Fleet under a leasing agreement. Ukraine is a republic under a semi-presidential system with separate legislative, executive, and judicial branches. Since the dissolution of the Soviet Union, Ukraine continues to maintain the second largest military in Europe, after that of Russia. The country is home to 46 million people, 77.8 percent of whom are ethnic Ukrainians, with sizable minorities of Russians (17%), Belarusians and Romanians. The Ukrainian language is the official language in Ukraine. Russian is also widely spoken. The dominant religion in the country is Eastern Orthodox Christianity, which has heavily influenced Ukrainian architecture, literature and music.

Early history

Human settlement in Ukraine and its vicinity dates back to 32,000 BCE, with evidence of the Gravettian culture in the Crimean Mountains. By 4,500 BCE, the Neolithic Cucuteni-Trypillian Culture flourished in a wide area that included parts of modern Ukraine including Trypillia and the entire Dnieper-Dniester region. During the Iron Age, the land was inhabited by Cimmerians, Scythians, and Sarmatians. Between 700 BC and 200 BC it was part of the Scythian Kingdom, or Scythia.

Later, colonies of Ancient Greece, Ancient Rome, and the Byzantine Empire, such as Tyras, Olbia, and Hermonassa, were founded, beginning in the 6th century BC, on the northeastern shore of the Black Sea, and thrived well into the 6th century AD. The Goths stayed in the area but came under the sway of the Huns from the 370s AD. In the 7th century AD, the territory of eastern Ukraine was the center of Old Great Bulgaria. At the end of the century, the majority of Bulgar tribes migrated in different directions, and the Khazars took over much of the land.

Golden Age of Kiev

The Kievan Rus' were founded by the Rus' people, Varangians who first settled around Ladoga and Novgorod, then gradually moved southward eventually reaching Kiev about 880. The Kievan Rus' included the western part of modern Ukraine, Belarus, with larger part of it situated on the territory of modern Russia. According to the Primary Chronicle the Rus' elite initially consisted of Varangians from Scandinavia.

During the 10th and 11th centuries, it became the largest and most powerful state in Europe. In the following centuries, it laid the foundation for the national identity of Ukrainians and Russians. Kiev, the capital of modern Ukraine, became the most important city of the Rus'.

The Varangians later became assimilated into the local Slavic population and became part of the Rus' first dynasty, the Rurik Dynasty. Kievan Rus' was composed of several principalities ruled by the interrelated Rurikid Princes. The seat of Kiev, the most prestigious and influential of all principalities, became the subject of many rivalries among Rurikids as the most valuable prize in their quest for power.

The Golden Age of Kievan Rus' began with the reign of Vladimir the Great (980–1015), who turned Rus' toward Byzantine Christianity. During the reign of his son, Yaroslav the Wise (1019–1054), Kievan Rus' reached the zenith of its cultural development and military power. This was followed by the state's increasing fragmentation as the relative importance of regional powers rose again. After a final resurgence under the rule of Vladimir Monomakh (1113–1125) and his son Mstislav (1125–1132), Kievan Rus' finally disintegrated into separate principalities following Mstislav's death.

In the 11th and 12th centuries, constant incursions by nomadic Turkic tribes, such as the Pechenegs and the Kipchaks, caused a massive migration of Slavic populations to the safer, heavily forested regions of the north. The 13th century Mongol invasion devastated Kievan Rus'. Kiev was totally destroyed in 1240. On the Ukrainian territory, the state of Kievan Rus' was succeeded by the principalities of Halych and Volodymyr-Volynskyi, which were merged into the state of Galicia-Volhynia.

Foreign domination

In the mid-14th century, Casimir III of Poland gained control of Galicia-Volhynia, while the heartland of Rus', including Kiev, became the territory of the Gediminas, of the Grand Duchy of Lithuania, after the Battle on the Irpen' River. Following the 1386 Union of Krevo, a dynastic union between Poland and Lithuania, much of what became northern Ukraine was ruled by the increasingly Slavicised local Lithuanian nobles as part of the Grand Duchy of Lithuania.

By 1569, the Union of Lublin formed the Polish–Lithuanian Commonwealth, and a significant part of Ukrainian territory was moved from Lithuanian rule to the Polish Crown, thus becoming Polish territory. Under the cultural and political pressure of Polonisation, many upper-class people of Polish Ruthenia (another term for the land of Rus) converted to Catholicism and became indistinguishable from the Polish nobility. Thus, the commoners, deprived of their native protectors among Rus nobility, turned for protection to the Cossacks, who remained fiercely Orthodox. The Cossacks tended to turn to violence against those they perceived as enemies, particularly the Polish state and its representatives.

In the mid-17th century, a Cossack military quasi-state, the Zaporozhian Host, was established by the Dnieper Cossacks and the Ruthenian peasants fleeing Polish serfdom. Poland had little real control of this land, yet they found the Cossacks to be a useful fighting force against the Turks and Tatars, and at times the two allied in military campaigns. However, the continued enserfment of peasantry by the Polish nobility, emphasized by the Commonwealth's fierce exploitation of the workforce, and most importantly, the suppression of the Orthodox Church pushed the allegiances of Cossacks away from Poland.

The Cossacks aspired to have representation in Polish Sejm, recognition of Orthodox traditions and the gradual expansion of the Cossack Registry. These were all vehemently rejected by the Polish nobility, who had power in the Sejm. The Cossacks eventually turned for protection to Orthodox Russia, a decision which would later lead towards the downfall of the Polish–Lithuanian state, and the preservation of the Orthodox Church and in Ukraine.

In 1648, Bohdan Khmelnytsky led the largest of the Cossack uprisings against the Commonwealth and the Polish king John II Casimir, starting a chain of events that led to Russia taking over Ukraine. Left-bank Ukraine was eventually integrated into Muscovite Russia as the Cossack Hetmanate, following the 1654 Treaty of Pereyaslav and the ensuing Russo-Polish War. After the partitions of Poland at the end of the 18th century by Prussia, Habsburg Austria, and Russia, Western Ukrainian Galicia was taken over by Austria, while the rest of Ukraine was progressively incorporated into the Russian Empire.

The Crimean Khanate was one of the strongest powers in Eastern Europe until the 18th century; at one point it even succeeded, under the Crimean khan Devlet I Giray, to devastate Moscow. The Russian population of the borderlands suffered annual Tatar invasions and tens of thousands of soldiers were required to protect the southern boundaries. From the beginning of the 16th century until the end of 17th century the Crimean Tatar raider bands made almost annual forays into agricultural Slavic lands searching for captives to sell as slaves. According to Orest Subtelny, "...from 1450 to 1586, eighty-six Tatar raids were recorded, and from 1600 to 1647, seventy." In 1688, Tatars captured a record number of 60,000 Ukrainians. This was a heavy burden for the state, and slowed its social and economic development. Since Crimean Tatars did not permit settlement of Russians to southern regions where the soil is better and the season is long enough, Muscovy had to depend on poorer regions and labour intensive agriculture. Poland-Lithuania, Moldavia and Wallachia were also subjected to extensive slave raiding. The Crimean Khanate was conquered by the Russian Empire in 1778, bringing an end to what remained of Mongol and Tatar rule in Europe.

The Ruin

In 1657–1686 came "The Ruin," a devastating 30-year war amongst Russia, Poland, Turks and Cossacks for control of Ukraine, which occurred at about the same time as the Deluge of Poland. For three years, Khmelnytsky's armies controlled present-day western and central Ukraine, but, deserted by his Tatar allies, he suffered a crushing defeat at Berestechko, and turned to the Russian Czar for help.

In 1654, Khmelnytsky signed the Treaty of Pereiaslav, forming a military and political alliance with Russia that acknowledged loyalty to the Czar. The wars escalated in intensity with hundreds of thousands of deaths. Defeat came in 1686 as the "Eternal Peace" between Russia and Poland gave Kiev and the Cossack lands east of the Dnieper over to Russian rule and the Ukrainian lands west of the Dnieper to Poland.

In 1709 Cossack Hetman Ivan Mazepa (1687–1709) sided with Sweden against Russia in the Great Northern War (1700–1721). Mazepa, a member of the Cossack nobility, received an excellent education abroad and proved to be a brilliant political and military leader enjoying good relations with the Romanov dynasty. After Peter the Great became czar, Mazepa as hetman gave him more than twenty years of loyal military and diplomatic service and was well rewarded.

Eventually Peter recognized that in order to consolidate and modernize Russia's political and economic power it was necessary to do away with the hetmanate and Ukrainian and Cossack aspirations to autonomy. Mazepa accepted Polish invitations to join the Poles and Swedes against Russia. The move was disastrous for the hetmanate, Ukrainian autonomy, and Mazepa. He died in exile after fleeing from the Battle of Poltava (1709), where the Swedes and their Cossack allies suffered a catastrophic defeat at the hands of Peter's Russian forces

The hetmanate was abolished in 1764; the Zaporizhska Sich abolished in 1775, as Russia centralized control over its lands. As part of the partitioning of Poland in 1772, 1793, and 1795, the Ukrainian lands west of the Dnieper were divided between Russia and Austria. From 1737 to 1834, expansion into the northern Black Sea littoral and the eastern Danube valley was a cornerstone of Russian foreign policy.

Lithuanians and Poles controlled vast estates in Ukraine, and were a law unto themselves. Judicial rulings from Cracow were routinely flouted, while peasants were heavily taxed and practically tied to the land as serfs. Occasionally the landowners battled each other using armies of Ukrainian peasants. The Poles and Lithuanians were Roman Catholics and tried with some success to convert the Orthodox lesser nobility. In 1596 they set up the "Greek-Catholic" or Uniate Church, under the authority of the Pope but using Eastern rituals; it dominates western Ukraine to this day. Tensions between the Uniates and the Orthodox were never resolved, and the religious differentiation left the Ukrainian Orthodox peasants leaderless, as they were reluctant to follow the Ukrainian nobles.

Cossacks led an uprising, called Koliivshchyna, starting in the Ukrainian borderlands of the Polish–Lithuanian Commonwealth in 1768. Ethnicity as one root cause of this revolt, which included Ukrainian violence that killed tens of thousands of Poles and Jews. Religious warfare also broke out between Ukrainian groups. Increasing conflict between Uniate and Orthodox parishes along the newly reinforced Polish-Russian border on the Dnepr River in the time of Catherine II set the stage for the uprising. As Uniate religious practices had become more Latinized, Orthodoxy in this region drew even closer into dependence on the Russian Orthodox Church. Confessional tensions also reflected opposing Polish and Russian political allegiances.

After the Russians annexed the Crimean Khanate in 1783, the region was settled by migrants from other parts of Ukraine. Despite the promises of Ukrainian autonomy given by the Treaty of Pereyaslav, the Ukrainian elite and the Cossacks never received the freedoms and the autonomy they were expecting from Imperial Russia. However, within the Empire, Ukrainians rose to the highest Russian state and church offices. At a later period, tsarists established a policy of Russification of Ukrainian lands, suppressing the use of the Ukrainian language in print, and in public.

19th century, World War I and revolution

In the 19th century, Ukraine was a rural area largely ignored by Russia and Austria. With growing urbanization and modernization, and a cultural trend toward romantic nationalism, a Ukrainian intelligentsia committed to national rebirth and social justice emerged. The serf-turned-national-poet Taras Shevchenko (1814–1861) and the political theorist Mykhailo Drahomanov (1841–1895) led the growing nationalist movement.

After Ukraine and Crimea became aligned with the Russian Empire Russo-Turkish War (1768–1774), significant German immigration German Russian Colonies occurred after it was encouraged by Catherine the Great and her immediate successors. Immigration was encouraged into Ukraine and especially the Crimea by Catherine in her proclamation of open migration to the Russian Empire. Immigration was encouraged for Germans and other Europeans to thin the previously dominant Turk population and encourage more complete use of farmland.

Beginning in the 19th century, there was a continuous migration from Ukraine to settle the distant areas of the Russian Empire. According to the 1897 census, there were 223,000 ethnic Ukrainians in Siberia and 102,000 in Central Asia. Between 1896 and 1906, after the construction of the trans-Siberian railway, a total of 1.6 million Ukrainians migrated eastward.

Nationalist and socialist parties developed in the late 19th century. Austrian Galicia, which enjoyed substantial political freedom under the relatively lenient rule of the Habsburgs, became the center of the nationalist movement.

Ukrainians entered World War I on the side of both the Central Powers, under Austria, and the Triple Entente, under Russia. 3.5 million Ukrainians fought with the Imperial Russian Army, while 250,000 fought for the Austro-Hungarian Army. During the war, Austro-Hungarian authorities established the Ukrainian Legion to fight against the Russian Empire. This legion was the foundation of the Ukrainian Galician Army that fought against the Bolsheviks and Poles in the post World War I period (1919–23). Those suspected of Russophile sentiments in Austria were treated harshly. Up to 5,000 supporters of the Russian Empire from Galicia were detained and placed in Austrian internment camps in Talerhof, Styria, and in a fortress at Terezín (now in the Czech Republic).

When World War I ended, several empires collapsed; among them were the Russian and Austrian empires. The Russian Revolution of 1917 ensued, and a Ukrainian national movement for self-determination reemerged, with heavy Communist/Socialist influence. During 1917–20, several separate Ukrainian states briefly emerged: the Ukrainian People's Republic, the Hetmanate, the Directorate and the pro-Bolshevik Ukrainian Soviet Socialist Republic (or Soviet Ukraine) successively established territories in the former Russian Empire; while the West Ukrainian People's Republic and the Hutsul Republic emerged briefly in the former Austro-Hungarian territory. This led to civil war, and an anarchist movement called the Black Army led by Nestor Makhno developed in Southern Ukraine during that war.

However, Poland defeated Western Ukraine in the Polish-Ukrainian War, but failed against the Bolsheviks in an offensive against Kiev. According to the Peace of Riga concluded between the Soviets and Poland, western Ukraine was officially incorporated into Poland, who in turn recognised the Ukrainian Soviet Socialist Republic in March 1919. Ukraine became a founding member of the Union of Soviet Socialist Republics or the Soviet Union in December 1922.

Inter-war Polish Ukraine

The war in Ukraine continued for another two years; by 1921, however, most of Ukraine had been taken over by the Soviet Union, while Galicia and Volhynia were incorporated into independent Poland.

A powerful underground Ukrainian nationalist movement rose in Poland in the 1920s and 1930s, led by the Ukrainian Military Organization and the Organization of Ukrainian Nationalists (OUN). The movement attracted a militant following among students and harassed the Polish authorities. Legal Ukrainian parties, the Ukrainian Catholic Church, an active press, and a business sector also flourished in Poland. Economic conditions improved in the 1920s, but the region suffered from the Great Depression in the 1930s.

Inter-war Soviet Ukraine

The civil war that eventually brought the Soviet government to power devastated Ukraine. It left over 1.5 million people dead and hundreds of thousands homeless. In addition, Soviet Ukraine had to face the famine of 1921. Seeing an exhausted Ukraine, the Soviet government remained very flexible during the 1920s. Thus, under the aegis of the Ukrainization policy pursued by the national Communist leadership of Mykola Skrypnyk, Soviet leadership encouraged a national renaissance in literature and the arts. The Ukrainian culture and language enjoyed a revival, as Ukrainisation became a local implementation of the Soviet-wide policy of Korenisation (literally indigenisation) policy. The Bolsheviks were also committed to introducing universal health care, education and social-security benefits, as well as the right to work and housing. Women's rights were greatly increased through new laws designed to wipe away centuries-old inequalities. Most of these policies were sharply reversed by the early 1930s after Joseph Stalin gradually consolidated power to become the de facto communist party leader.

The communists gave a privileged position to manual labor, the largest class in the cities, where Russians dominated. The typical worker was more attached to class identity than to ethnicity. Although there were incidents of ethnic friction among workers (in addition to Ukrainians and Russians there were significant numbers of Poles, Germans, Jews, and others in the Ukrainian workforce), industrial laborers had already adopted Russian culture and language to a significant extent. Workers whose ethnicity was Ukrainian were not attracted to campaigns of Ukrainianization or de-Russification in meaningful numbers, but remained loyal members of the Soviet working class. There was no significant antagonism between workers identifying themselves as Ukrainian or Russian.

Starting from the late 1920s, Ukraine was involved in the Soviet industrialisation and the republic's industrial output quadrupled during the 1930s.

The industrialisation had a heavy cost for the peasantry, demographically a backbone of the Ukrainian nation. To satisfy the state's need for increased food supplies and to finance industrialisation, Stalin instituted a program of collectivisation of agriculture as the state combined the peasants' lands and animals into collective farms and enforced the policies by the regular troops and secret police. Those who resisted were arrested and deported and the increased production quotas were placed on the peasantry. The collectivisation had a devastating effect on agricultural productivity. As the members of the collective farms were not allowed to receive any grain until sometimes unrealistic quotas were met, starvation in the Soviet Union became more common. In 1932–33, millions starved to death in a famine known as Holodomor or "Great Famine". Scholars are divided as to whether this famine fits the definition of genocide, but the Ukrainian parliament and other countries recognise it as such.

The famine claimed up to 10 million of Ukrainian lives as peasants' food stocks were forcibly removed by the Soviet government by the NKVD secret police. Some explanations for the causes for the excess deaths in rural areas of Ukraine and Kazakhstan during 1931–34 has been given by dividing the causes into three groups: objective non-policy-related factors, like the drought of 1931 and poor weather in 1932; inadvertent result of policies with other objectives, like rapid industrialization, socialization of livestock, and neglected crop rotation patterns; and deaths caused intentionally by a starvation policy. The Communist leadership perceived famine not as a humanitarian catastrophe but as a means of class struggle and used starvation as a punishment tool to force peasants into collective farms. It was largely the same groups of individuals who were responsible for the mass killing operations during the civil war, collectivisation, and the Great Terror. These groups were associated with Efim Georgievich Evdokimov (1891–1939) and operated in Ukraine during the civil war, in the North Caucasus in the 1920s, and in the Secret Operational Division within General State Political Administration (OGPU) in 1929–31. Evdokimov transferred into Communist Party administration in 1934, when he became Party secretary for North Caucasus Krai. But he appears to have continued advising Joseph Stalin and Nikolai Yezhov on security matters, and the latter relied on Evdokimov's former colleagues to carry out the mass killing operations that are known as the Great Terror in 1937–38.

With Joseph Stalin's change of course in the late 1920s, however, Moscow's toleration of Ukrainian national identity came to an end. Systematic state terror of the 1930s destroyed Ukraine's writers, artists, and intellectuals; the Communist Party of Ukraine was purged of its "nationalist deviationists". Two waves of Stalinist political repression and persecution in the Soviet Union (1929–34 and 1936–38) resulted in the killing of some 681,692 people; this included four-fifths of the Ukrainian cultural elite and three quarters of all the Red Army's higher-ranking officers.

World War II

Following the Invasion of Poland in September 1939, German and Soviet troops divided the territory of Poland. Thus, Eastern Galicia and Volhynia with their Ukrainian population became reunited with the rest of Ukraine. The unification that Ukraine achieved for the first time in its history was a decisive event in the history of the nation.

After France surrendered to Germany, Romania ceded Bessarabia and northern Bukovina to Soviet demands. The Ukrainian SSR incorporated northern and southern districts of Bessarabia, the northern Bukovina, and the Soviet-occupied Hertsa region. But it ceded the western part of the Moldavian Autonomous Soviet Socialist Republic to the newly created Moldavian Soviet Socialist Republic. All these territorial gains were internationally recognised by the Paris peace treaties of 1947.

German armies invaded the Soviet Union on June 22, 1941, thereby initiating four straight years of incessant total war. The Axis allies initially advanced against desperate but unsuccessful efforts of the Red Army. In the encirclement battle of Kiev, the city was acclaimed as a "Hero City", because the resistance by the Red Army and by the local population was fierce. More than 600,000 Soviet soldiers (or one quarter of the Western Front) were killed or taken captive there.

Although the wide majority of Ukrainians fought alongside the Red Army and Soviet resistance, some elements of the Ukrainian nationalist underground created an anti-Soviet nationalist formation in Galicia, the Ukrainian Insurgent Army (1942) that at times engaged the Nazi forces and continued to fight the USSR in the years after the war. Using guerilla war tactics, the insurgents targeted for assassination and terror those who they perceived as representing, or cooperating at any level with, the Soviet state.

At the same time another nationalist movement fought alongside the Nazis. In total, the number of ethnic Ukrainians that fought in the ranks of the Soviet Army is estimated from 4.5 million to 7 million. The pro-Soviet partisan guerilla resistance in Ukraine is estimated to number at 47,800 from the start of occupation to 500,000 at its peak in 1944; with about 50 percent of them being ethnic Ukrainians. Generally, the Ukrainian Insurgent Army's figures are very undependable, ranging anywhere from 15,000 to as much as 100,000 fighters.

Initially, the Germans were even hailed as liberators by some western Ukrainians, who had only joined the Soviet Union in 1939. However, brutal German rule in the occupied territories eventually turned its supporters against the occupation. Nazi administrators of conquered Soviet territories made little attempt to exploit the population of Ukrainian territories' dissatisfaction with Stalinist political and economic policies. Instead, the Nazis preserved the collective-farm system, systematically carried out genocidal policies against Jews, deported others to work in Germany, and began a systematic depopulation of Ukraine (along with Poland) to prepare it for German colonisation, which included a food blockade on Kiev.

The vast majority of the fighting in World War II took place on the Eastern Front, and Nazi Germany suffered 93 percent of all its casualties there. The total losses inflicted upon the Ukrainian population during the war are estimated between five and eight million, including over half a million Jews killed by the Einsatzgruppen, sometimes with the help of local collaborators. Of the estimated 8.7 million Soviet troops who fell in battle against the Nazis, 1.4 million were ethnic Ukrainians. So to this day, Victory Day is celebrated as one of ten Ukrainian national holidays.

Post–World War II

The republic was heavily damaged by the war, and it required significant efforts to recover. More than 700 cities and towns and 28,000 villages were destroyed. The situation was worsened by a famine in 1946–47, which was caused by a drought and the wartime infrastructure destruction. This famine took away tens of thousands of lives.

In 1945, the Ukrainian SSR became one of the founding members of the United Nations organization. First Soviet computer MESM was built in Kiev Institute of Electrotechnology and became operational in 1950.

Postwar ethnic cleansing occurred in the newly expanded Soviet Union. According to statistics, as of 1 January 1953, Ukrainians were second only to Russians among adult "special deportees", comprising 20% of the total. Apart from Ukrainians, over 450,000 ethnic Germans from Ukraine and more than 200,000 Crimean Tatars were victims of forced deportations.

Following the death of Stalin in 1953, Nikita Khrushchev became the new leader of the USSR. Being the First Secretary of the Communist Party of Ukrainian SSR in 1938–49, Khrushchev was intimately familiar with the republic and after taking power union-wide, he began to emphasize the friendship between the Ukrainian and Russian nations. In 1954, the 300th anniversary of the Treaty of Pereyaslav was widely celebrated, and in particular, Crimea was transferred from the Russian SFSR to the Ukrainian SSR.

Already by 1950, the republic fully surpassed pre-war levels of industry and production. During the 1946–1950 five year plan nearly 20 percent of the Soviet budget was invested in Soviet Ukraine, a five percent increase from prewar plans. As a result the Ukrainian workforce rose 33.2 percent from 1940 to 1955 while industrial output grew 2.2 times in that same period. Soviet Ukraine soon became a European leader in industrial production. It also became an important center of the Soviet arms industry and high-tech research. Such an important role resulted in a major influence of the local elite.

Many members of the Soviet leadership came from Ukraine, most notably Leonid Brezhnev, who would later oust Khrushchev and become the Soviet leader from 1964 to 1982, as well as many prominent Soviet sports players, scientists and artists. On April 26, 1986, a reactor in the Chernobyl Nuclear Power Plant exploded, resulting in the Chernobyl disaster, the worst nuclear reactor accident in history, at least until the Fukushima Daiichi nuclear disaster. At the time of the accident seven million people lived in the contaminated territories, including 2.2 million in Ukraine. After the accident, a new city, Slavutych, was built outside the exclusion zone to house and support the employees of the plant which was decommissioned in 2000. A report prepared by the International Atomic Energy Agency and World Health Organization attributed 56 direct deaths to the accident and estimated that there may have been 4,000 extra cancer deaths.

Independence

On July 16, 1990, the new parliament adopted the Declaration of State Sovereignty of Ukraine. The declaration established the principles of the self-determination of the Ukrainian nation, its democracy, political and economic independence, and the priority of Ukrainian law on the Ukrainian territory over Soviet law. A month earlier, a similar declaration was adopted by the parliament of the Russian SFSR. This started a period of confrontation between the central Soviet, and new republican authorities. In August 1991, a conservative faction among the Communist leaders of the Soviet Union attempted a coup to remove Mikhail Gorbachev and to restore the Communist party's power. After the attempt failed, on August 24, 1991 the Ukrainian parliament adopted the Act of Independence in which the parliament declared Ukraine as an independent democratic state.

A referendum and the first presidential elections took place on December 1, 1991. That day, more than 90 percent of the Ukrainian people expressed their support for the Act of Independence, and they elected the chairman of the parliament, Leonid Kravchuk to serve as the first President of the country. At the meeting in Brest, Belarus on December 8, followed by Alma Ata meeting on December 21, the leaders of Belarus, Russia, and Ukraine, formally dissolved the Soviet Union and formed the Commonwealth of Independent States (CIS).

Although the idea of an independent Ukrainian nation had previously not existed in the 20th century in the minds of international policy makers, Ukraine was initially viewed as a republic with favorable economic conditions in comparison to the other regions of the Soviet Union. However, the country experienced deeper economic slowdown than some of the other former Soviet Republics. During the recession, Ukraine lost 60 percent of its GDP from 1991 to 1999, and suffered five-digit inflation rates. Dissatisfied with the economic conditions, as well as the amounts of crime and corruption, Ukrainians protested and organised strikes.

The Ukrainian economy stabilized by the end of the 1990s. A new currency, the hryvnia, was introduced in 1996. Since 2000, the country has enjoyed steady real economic growth averaging about seven percent annually. A new Constitution of Ukraine was adopted under second President Leonid Kuchma in 1996, which turned Ukraine into a semi-presidential republic and established a stable political system. Kuchma was, however, criticized by opponents for corruption, electoral fraud, discouraging free speech and concentrating too much of power in his office. He also repeatedly transferred public property into the hands of loyal oligarchs.

In 2004, Viktor Yanukovych, then Prime Minister, was declared the winner of the presidential elections, which had been largely rigged, as the Supreme Court of Ukraine later ruled. The results caused a public outcry in support of the opposition candidate, Viktor Yushchenko, who challenged the outcome of the elections. This resulted in the peaceful Orange Revolution, bringing Viktor Yushchenko and Yulia Tymoshenko to power, while casting Viktor Yanukovych in opposition. Yanukovych returned to a position of power in 2006, when he became Prime Minister in the Alliance of National Unity, until snap elections in September 2007 made Tymoshenko Prime Minister again. Yanukovych was elected President in 2010.

Conflicts with Russia over the price of natural gas briefly stopped all gas supplies to Ukraine in 2006 and again in 2009, leading to gas shortages in several other European countries.

Historical maps of Ukraine

The Ukrainian state has occupied a number of territories since its initial foundation. Most of these territories have been located within Eastern Europe, however, as depicted in the maps in the gallery below, has also at times extended well into Eurasia and South-Eastern Europe. At times there has also been a distinct lack of a Ukrainian state, as its territories were on a number of occasions, annexed by its more powerful neighbours.

Ukrainian customs are heavily influenced by Christianity, which is the dominant religion in the country. Gender roles also tend to be more traditional, and grandparents play a greater role in raising children than in the West. The culture of Ukraine has been also influenced by its eastern and western neighbours, which is reflected in its architecture, music and art.

The Communist era had quite a strong effect on the art and writing of Ukraine. In 1932, Stalin made socialist realism state policy in the Soviet Union when he promulgated the decree "On the Reconstruction of Literary and Art Organisations". This greatly stifled creativity. During the 1980s glasnost (openness) was introduced and Soviet artists and writers again became free to express themselves as they wanted.

The tradition of the Easter egg, known as pysanky, has long roots in Ukraine. These eggs were drawn on with wax to create a pattern; then, the dye was applied to give the eggs their pleasant colours, the dye did not affect the previously wax-coated parts of the egg. After the entire egg was dyed, the wax was removed leaving only the colourful pattern. This tradition is thousands of years old, and precedes the arrival of Christianity to Ukraine. In the city of Kolomya near the foothills of the Carpathian mountains in 2000 was built the museum of Pysanka which won a nomination as the monument of modern Ukraine in 2007, part of the Seven Wonders of Ukraine action.

Language

According to the Constitution, the state language of Ukraine is Ukrainian. Russian, which was the de facto official language of the Soviet Union, is widely spoken, especially in eastern and southern Ukraine. According to the 2001 census, 67.5 percent of the population declared Ukrainian as their native language and 29.6 percent declared Russian. Most native Ukrainian speakers know Russian as a second language.

These details result in a significant difference across different survey results, as even a small restating of a question switches responses of a significant group of people. Ukrainian is mainly spoken in western and central Ukraine. In western Ukraine, Ukrainian is also the dominant language in cities (such as Lviv). In central Ukraine, Ukrainian and Russian are both equally used in cities, with Russian being more common in Kiev, while Ukrainian is the dominant language in rural communities. In eastern and southern Ukraine, Russian is primarily used in cities, and Ukrainian is used in rural areas.

For a large part of the Soviet era, the number of Ukrainian speakers declined from generation to generation, and by the mid-1980s, the usage of the Ukrainian language in public life had decreased significantly. Following independence, the government of Ukraine began restoring the image and usage of Ukrainian language through a policy of Ukrainisation. Today, all foreign films and TV programs, including Russian ones, are subbed or dubbed in Ukrainian.

According to the Constitution of the Autonomous Republic of Crimea, Ukrainian is the only state language of the republic. However, the republic's constitution specifically recognises Russian as the language of the majority of its population and guarantees its usage 'in all spheres of public life'. Similarly, the Crimean Tatar language (the language of 12 percent of population of Crimea) is guaranteed a special state protection as well as the 'languages of other ethnicities'. Russian speakers constitute an overwhelming majority of the Crimean population (77 percent), with Ukrainian speakers comprising just 10.1 percent, and Crimean Tatar speakers 11.4 percent. But in everyday life the majority of Crimean Tatars and Ukrainians in Crimea use Russian.

Literature

The history of Ukrainian literature dates back to the 11th century, following the Christianisation of the Kievan Rus’. The writings of the time were mainly liturgical and were written in Old Church Slavonic. Historical accounts of the time were referred to as chronicles, the most significant of which was the Primary Chronicle. Literary activity faced a sudden decline during the Mongol invasion of Rus'.

Ukrainian literature again began to develop in the 14th century, and was advanced significantly in the 16th century with the introduction of print and with the beginning of the Cossack era, under both Russian and Polish dominance. The Cossacks established an independent society and popularized a new kind of epic poems, which marked a high point of Ukrainian oral literature. These advances were then set back in the 17th and early 18th centuries, when publishing in the Ukrainian language was outlawed and prohibited. Nonetheless, by the late 18th century modern literary Ukrainian finally emerged.

The 19th century initiated a vernacular period in Ukraine, led by Ivan Kotliarevsky’s work Eneyida, the first publication written in modern Ukrainian. By the 1830s, Ukrainian romanticism began to develop, and the nation’s most renowned cultural figure, romanticist poet-painter Taras Shevchenko emerged. Where Ivan Kotliarevsky is considered to be the father of literature in the Ukrainian vernacular; Shevchenko is the father of a national revival.

Then, in 1863, use of the Ukrainian language in print was effectively prohibited by the Russian Empire. This severely curtained literary activity in the area, and Ukrainian writers were forced to either publish their works in Russian or release them in Austrian controlled Galicia. The ban was never officially lifted, but it became obsolete after the revolution and the Bolsheviks’ coming to power.

Ukrainian literature continued to flourish in the early Soviet years, when nearly all literary trends were approved. These policies faced a steep decline in the 1930s, when Stalin implemented his policy of socialist realism. The doctrine did not necessarily repress the Ukrainian language, but it required writers to follow a certain style in their works. Literary activities continued to be somewhat limited under the communist party, and it was not until Ukraine gained its independence in 1991 when writers were free to express themselves as they wished.

Architecture

Ukrainian architecture is a term that describes the motifs and styles that are found in structures built in modern Ukraine, and by Ukrainians worldwide. These include initial roots which were established in the Eastern Slavic state of Kievan Rus'. After the 12th century, the distinct architectural history continued in the principalities of Galicia-Volhynia. During the epoch of the Zaporozhian Cossacks, a new style unique to Ukraine was developed under the western influences of the Polish–Lithuanian Commonwealth. After the union with the Tsardom of Russia, architecture in Ukraine began to develop in different directions, with many structures in the larger eastern, Russian-ruled area built in the styles of Russian architecture of that period, whilst the western Galicia was developed under Austro-Hungarian architectural influences, in both cases producing fine examples. Ukrainian national motifs would finally be used during the period of the Soviet Union and in modern independent Ukraine.

The great churches of the Rus', built after the adoption of Christianity in 988, were the first examples of monumental architecture in the East Slavic lands. The architectural style of the Kievan state, which quickly established itself, was strongly influenced by the Byzantine. Early Eastern Orthodox churches were mainly made of wood, with the simplest form of church becoming known as a cell church. Major cathedrals often featured scores of small domes, which led some art historians to take this as an indication of the appearance of pre-Christian pagan Slavic temples.

Several examples of these churches survive to this day; however, during the 16th, 17th, and 18th centuries, many were externally rebuilt in the Ukrainian Baroque style (see below). Examples include the grand St. Sophia of Kiev – the year 1017 is the earliest record of foundation laid, Church of the Saviour at Berestove – built from 1113 to 1125, and St. Cyril's Church, circa 12th century. All can still be found in the Ukrainian capital. Several buildings were reconstructed during the late-19th century, including the Assumption Cathedral in Volodymyr-Volynskyi, built in 1160 and reconstructed in 1896–1900, the Paraskevi church in Chernihiv, built in 1201 with reconstruction done in the late 1940s, and the Golden gates in Kiev, built in 1037 and reconstructed in 1982. The latter's reconstruction was criticized by some art and architecture historians as a revivalist fantasy. Unfortunately little secular or vernacular architecture of Kievan Rus' has survived.

As Ukraine became increasingly integrated into the Russian Empire, Russian architects had the opportunity to realize their projects in the picturesque landscape that many Ukrainian cities and regions offered. St. Andrew's Church of Kiev (1747–1754), built by Bartolomeo Rastrelli, is a notable example of Baroque architecture, and its location on top of the Kievan mountain made it a recognizable monument of the city. An equally notable contribution of Rasetrelli was the Mariyinsky Palace, which was built to be a summer residence to Russian Empress Elizabeth. During the reign of the last Hetman of Ukraine, Kirill Razumovsky, many of the Cossack Hetmanate's towns such as Hlukhiv, Baturyn and Koselets had grandiose projects built by the appointed architect of Little Russia, Andrey Kvasov. Russia, winning successive wars over the Ottoman Empire and its vassal Crimean Khanate, eventually annexed the whole south of Ukraine and Crimea. Renamed New Russia, these lands were to be colonized, and new cities such as the Nikolayev, Odessa, Kherson and Sevastopol were founded. These would contain notable examples of Imperial Russian architecture.

In 1934, the capital of Soviet Ukraine moved from Kharkiv to Kiev. During the preceding years, the city was seen as only a regional centre, and hence received little attention. All of that was to change, but at a great price. By this point, the first examples of Stalinist architecture were already showing, and, in light of the official policy, a new city was to be built on top of the old one. This meant that much-admired examples such as the St. Michael's Golden-Domed Monastery were destroyed. Even the St. Sophia Cathedral was under threat. Also, the Second World War contributed to the wreckage. After the war, a new project for the reconstruction of central Kiev was unveiled. This transformed the Khreshchatyk avenue into one of the most notable examples of Stalinism in Architecture. However, by 1955, the new politics of architecture once again promptly stopped the project from fully being realised.

The task for modern Ukrainian architecture is diverse application of modern aesthetics, the search for an architect's own artistic style and inclusion of the existing historico-cultural environment. An example of modern Ukrainian architecture is the reconstruction and renewal of the Maidan Nezalezhnosti in central Kiev, despite the limit set by narrow space within the plaza, the engineers were able to blend together the uneven landscape and also use underground space to set a new shopping centre.

A major project, which may take up most of the 21st century, is the construction of the Kiev City-Centre on the Rybalskyi Peninsula, which, when finished, will include a dense skyscraper park amid the picturesque landscape of the Dnieper.

Music

Music is a major part of Ukrainian culture, with a long history and many influences. From traditional folk music, to classical and modern rock, Ukraine has produced a long list of internationally recognized musical talent including Tchaikovsky and Okean Elzy. Elements from traditional Ukrainian folk music made their way into Western music and even into modern Jazz.

Ukraine found itself at the crossroads of Asia and Europe and this is reflected within the music in a perplexing mix of exotic melismatic singing with chordal harmony which does not always easily fit the rules of traditional Western European harmony. The most striking general characteristic of authentic ethnic Ukrainian folk music is the wide use of minor modes or keys which incorporate augmented 2nd intervals. This is an indication that the major-minor system developed in Western European music did not become as entrenched or as sophisticated in Ukraine. However, during the Baroque period, music was an important discipline for those that had received a higher education in Ukraine. It had a place of considerable importance in the curriculum of the Kyiv-Mohyla Academy. Much of the nobility was well versed in music with many Ukrainian Cossack leaders such as (Mazepa, Paliy, Holovatyj, Sirko) being accomplished players of the kobza, bandura or torban.

In the course of the 18th century in the Russian Empire court musicians were typically trained at the music academy in Hlukhiv, and largely came from Ukraine. Notable performers of the era include Tymofiy Bilohradsky who later studied lute under Sylvius Leopold Weiss in Dresden, his daughter Yelyzaveta who was a famous operatic soprano, and Oleksiy Rozumovsky, a court bandurist and the morganatic husband of Empress Elizabeth. The first dedicated musical academy was set up in Hlukhiv, Ukraine in 1738 and students were taught to sing, play violin and bandura from manuscripts. As a result many of the earliest composers and performers within the Russian empire were ethnically Ukrainian, having been born or educated in Hlukhiv, or had been closely associated with this music school. See: Dmytro Bortniansky, Maksym Berezovsky, Artemiy Vedel.

Ukrainian classical music falls into three distinct categories defined by whether the composer was of Ukrainian ethnicity living in Ukraine, a composer of non-Ukrainian ethnicity who was born or at some time was a citizen of Ukraine, or an ethnic Ukrainian living outside of Ukraine within the Ukrainian diaspora. The music of these three groups differs considerably, as do the audiences for whom they cater.

The first category is closely tied with the Ukrainian national school of music spearheaded by Mykola Lysenko. It includes such composers as Kyrylo Stetsenko, Mykola Leontovych, Levko Revutsky, Borys Lyatoshynsky, Mykola Vilinsky. Most of their music contains Ukrainian folk figures and are composed to Ukrainian texts. On the other hand, the second category is of particular importance and international visibility, because of the large percentage of ethnic minorities in urban Ukraine. This category includes such composers as Franz Xavier Mozart, Isaak Dunayevsky, Rheinhold Gliere, Yuliy Meitus and Sergei Prokofiev, performers Volodymyr Horovyts, David Oistrakh, Sviatoslav Richter and Isaac Stern. The music of these composers rarely contains Ukrainian folk motives and more often is written to the texts of Russian or Polish poets. Whilst the third category includes a number of prominent individuals who are often not part of the mainstream Ukrainian culture but who have made a significant impact on music in Ukraine, while living outside of its borders. These include historic individuals such as: Bortniansky, Berezovsky, Vedel, Tuptalo and Titov. It also contains "Soviet" composers such as Mykola Roslavets, Isaak Dunayevsky who were born in Ukraine but who moved to other cultural centres within the Soviet Union. In North America we have Mykola Fomenko, Yuriy Oliynyk, Zinoviy Lavryshyn and Wasyl Sydorenko.

Since the mid 1960s, Western influenced pop music, in its various forms, that has been growing in popularity in Ukraine. One of the most important and truly original musicians to come out of Ukraine in recent years is the ultra avant-garde folk singer and harmonium player Mariana Sadovska. Ukrainian pop and folk music arose with the international popularity of groups like Vopli Vidoplyasova, Viy[8] and Okean Elzy.

Weaving and embroidery

Artisan textile arts play an important role in Ukrainian culture, especially in Ukrainian wedding traditions. Ukrainian embroidery, weaving and lace-making are used in traditional folk dress and in traditional celebrations. Ukrainian embroidery varies depending on the region of origin and the designs have a long history of motifs, compositions, choice of colors and types of stitches. Use of color is very important and has roots in Ukrainian folklore. Embroidery motifs found in different parts of Ukraine are preserved in the Rushnyk Museum in Pereiaslav-Khmelnytskyi.

National dress is woven and highly decorated. Weaving with handmade looms is still practised in the village of Krupove, situated in Rivne Oblast. The village is the birth place of two famous personalities in the scene of national crafts fabrication. Nina Myhailivna and Uliana Petrivna with international recognition. In order to preserve this traditional knowledge the village is planning to open a local weaving center, a museum and weaving school.

Sport

Ukraine greatly benefited from the Soviet emphasis on physical education. Such policies left Ukraine with hundreds of stadia, swimming pools, gymnasia, and many other athletic facilities. The most popular sport is football. The top professional league is the Vyscha Liha ("premier league"). The two most successful teams in the Vyscha Liha are rivals FC Dynamo Kyiv and FC Shakhtar Donetsk. Although Shakhtar is the reigning champion of the Vyscha Liha, Dynamo Kyiv has been much more successful historically, winning two UEFA Cup Winners' Cups, one UEFA Super Cup, a record 13 USSR Championships and a record 12 Ukrainian Championships; while Shakhtar only won six Ukrainian championships and one and last UEFA Cup. Ukraine will host the Euro 2012 alongside Poland.

Some of the world's greatest athletes were Ukrainians such as the legend Sergey Bubka whose holding the record in the Pole vault; with a great strength, speed and gymnastic abilities, he is repeatedly voted the world's best athlete.

Many Ukrainians also played for the Soviet national football team, most notably Igor Belanov and Oleg Blokhin, winners of the prestigious Golden Ball Award for the best football player of the year. This award was only presented to one Ukrainian after the dissolution of the Soviet Union, Andriy Shevchenko, the current captain of the Ukrainian national football team. The national team made its debut in the 2006 FIFA World Cup, and reached the quarterfinals before losing to eventual champions, Italy. Ukrainians also fared well in boxing, where the brothers Vitaliy Klychko and Volodymyr Klychko have held world heavyweight championships.

Ukraine made its Olympic debut at the 1994 Winter Olympics. So far, Ukraine has been much more successful in Summer Olympics (96 medals in four appearances) than in the Winter Olympics (five medals in four appearances). Ukraine is currently ranked 35th by number of gold medals won in the All-time Olympic Games medal count, with every country above it, except for Russia, having more appearances.

Cuisine

The traditional Ukrainian diet includes chicken, pork, beef, fish and mushrooms. Ukrainians also tend to eat a lot of potatoes, grains, fresh and pickled vegetables. Popular traditional dishes include varenyky (boiled dumplings with mushrooms, potatoes, sauerkraut, cottage cheese or cherries), borscht (soup made of beets, cabbage and mushrooms or meat) and holubtsy (stuffed cabbage rolls filled with rice, carrots and meat). Ukrainian specialties also include Chicken Kiev and Kiev Cake. Ukrainians drink stewed fruit, juices, milk, buttermilk (they make cottage cheese from this), mineral water, tea and coffee, beer, wine and horilka.

At 603,700 square kilometres (233,100 sq mi) and with a coastline of 2,782 kilometres (1,729 mi), Ukraine is the world's 44th-largest country (after the Central African Republic, before Madagascar). It is the largest wholly European country and the second largest country in Europe (after the European part of Russia, before metropolitan France). It lies between latitudes 44° and 53° N, and longitudes 22° and 41° E.

The Ukrainian landscape consists mostly of fertile plains (or steppes) and plateaus, crossed by rivers such as the Dnieper (Dnipro), Seversky Donets, Dniester and the Southern Buh as they flow south into the Black Sea and the smaller Sea of Azov. To the southwest, the delta of the Danube forms the border with Romania. Its various regions have diverse geographic features ranging from the highlands to the lowlands. The country's only mountains are the Carpathian Mountains in the west, of which the highest is the Hora Hoverla at 2,061 metres (6,762 ft), and the Crimean Mountains on the Crimean peninsula, in the extreme south along the coast. However Ukraine also has a number of highland regions such as the Volyn-Podillia Upland (in the west) and the Near-Dnipro Upland (on the right bank of Dnieper); to the east there are the south-western spurs of the Central Russian Uplands over which runs the border with Russia. Near the Sea of Azov can be found the Donets Ridge and the Near Azov Upland. The snow melt from the mountains feeds the rivers, and natural changes in altitude form a sudden drop in elevation and create many opportunities to form waterfalls of Ukraine.

Significant natural resources in Ukraine include iron ore, coal, manganese, natural gas, oil, salt, sulfur, graphite, titanium, magnesium, kaolin, nickel, mercury, timber and an abundance of arable land. Despite this, the country faces a number of major environmental issues such as inadequate supplies of potable water; air and water pollution and deforestation, as well as radiation contamination in the north-east from the 1986 accident at the Chernobyl Nuclear Power Plant.

Regionalism

There are not only clear regional differences on questions of identity but historical cleavages remain evident at the level of individual social identification. Attitudes toward the most important political issue, relations with Russia, differed strongly between Lviv, identifying more with Ukrainian nationalism and the Ukrainian Greek Catholic Church, and Donetsk, predominantly Russian orientated and favorable to the Soviet era, while in central and southern Ukraine, as well as Kiev, such divisions were less important and there was less antipathy toward people from other regions (a poll by the Research & Branding Group held March 2010 showed that the attitude of the citizens of Donetsk to the citizens of Lviv was 79% positive and that the attitude of the citizens of Lviv to the citizens of Donetsk was 88% positive). However, all were united by an overarching Ukrainian identity based on shared economic difficulties, showing that other attitudes are determined more by culture and politics than by demographic differences.

Biodiversity

Ukraine is home to a very wide range of animals, fungi, micro-organisms and plants.

Animals

Ukraine is divided into two main zoological areas. One of these areas, in the west of the country, is made up of the borderlands of Europe, where there are species typical of mixed forests, the other is located in eastern Ukraine, where steppe-dwelling species thrive. In the forested areas of the country it is not uncommon to find lynxes, wolves, wild boar and martens, as well as many other similar species; this is especially true of the Carpathian mountains, where a large number of predatory mammals make their home, as well as a contingent of brown bears. Around Ukraine's lakes and rivers beavers, otters and mink make their home, whilst within, carp, bream and catfish are the most commonly found species of fish. In the central and eastern parts of the country, rodents such as hamsters and gophers are found in large numbers.

Fungi

More than 6600 species of fungi (including lichen-forming species) have been recorded from Ukraine., but this number is far from complete. The true total number of fungal species occurring in Ukraine, including species not yet recorded, is likely to be far higher, given the generally accepted estimate that only about 7% of all fungi worldwide have so far been discovered. Although the amount of available information is still very small, a first effort has been made to estimate the number of fungal species endemic to Ukraine, and 2217 such species have been tentatively identified.

Climate

Ukraine has a mostly temperate continental climate, although a more Mediterranean climate is found on the southern Crimean coast. Precipitation is disproportionately distributed; it is highest in the west and north and lowest in the east and southeast. Western Ukraine receives around 1,200 millimetres (47.2 in) of precipitation annually, while Crimea receives around 400 millimetres (15.7 in). Winters vary from cool along the Black Sea to cold farther inland. Average annual temperatures range from 5.5 °C (41.9 °F)–7 °C (44.6 °F) in the north, to 11 °C (51.8 °F)–13 °C (55.4 °F) in the south.
