Ukraine is a country in Eastern Europe. It is the second-largest country in Europe after Russia, which borders it to the east and northeast. Ukraine also borders Belarus to the north; Poland and Slovakia to the west; Hungary, Romania and Moldova to the southwest; and the Black Sea and the Sea of Azov to the south and southeast. Kyiv is Ukraine's capital and largest city, followed by Kharkiv, Odesa, and Dnipro. The official language is Ukrainian. Ukraine covers about 603,628 km2 (230,000 sq mi), with around 32 million people.
Humans have inhabited Ukraine since at least 32,000 BC. During the Middle Ages, it was the site of early Slavic expansion and later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. Kievan Rus' became the largest and most powerful realm in Europe in the 10th and 11th centuries, but gradually disintegrated into rival regional powers before being destroyed by the Mongols in the 13th century. For the next 600 years the area was contested, divided, and ruled by a variety of external powers, including the Grand Duchy of Lithuania, the Kingdom of Poland, the Polish–Lithuanian Commonwealth, the Austrian Empire, the Ottoman Empire, and the Tsardom of Russia.
The Cossack Hetmanate emerged in central Ukraine in the 17th century but was partitioned between Russia and Poland before being gradually absorbed by the Russian Empire in the 18th century. Ukrainian nationalism developed and, following the Russian Revolution in 1917, the short-lived Ukrainian People's Republic was formed. The Bolsheviks consolidated control over much of the former empire and established the Ukrainian Soviet Socialist Republic, which became a constituent republic of the Soviet Union in 1922. In the early 1930s, millions of Ukrainians died in the Holodomor, a human-made famine. During World War II, Ukraine was occupied by Germany and endured major battles and atrocities, resulting in 7 million civilians killed, including most Ukrainian Jews.
Ukraine gained independence in 1991 as the Soviet Union dissolved, declaring itself neutral. A new constitution was adopted in 1996 as the country transitioned to a free market liberal democracy amid endemic corruption and a legacy of state control. The Orange Revolution of 2004–2005 ushered in electoral and constitutional reforms. Resurgent political crises prompted a series of mass demonstrations in 2014 known as the Euromaidan, leading to a revolution, at the end of which Russia unilaterally occupied and annexed Ukraine's Crimean Peninsula, and pro-Russian unrest culminated in a war in Donbas with Russia and Russian-backed separatists. The 2022 Russian invasion of Ukraine began a new phase of the war.
Ukraine is a unitary state and its system of government is a semi-presidential republic. Ukraine's economy is a transition economy, with the lowest nominal GDP per capita in Europe as of 2024. Due to its extensive fertile land, the country is an important exporter of grain, though grain production has declined since 2022 due to the Russo-Ukrainian war, endangering global food security. Ukraine is considered a middle power in global affairs. Its military is the sixth largest in the world with the eighth largest defence budget, and operates one of the world's largest and most diverse drone fleets. Ukraine is a founding member of the United Nations and a member of the Council of Europe, the World Trade Organisation, and the OSCE. It is negotiating to join the European Union and applied to join NATO in 2022.
Name
The name of Ukraine is frequently interpreted as coming from the old Slavic term for 'borderland' as is the word krajina.
Another interpretation is that the name of Ukraine means "region" or "country".
In the English-speaking world during most of the 20th century, Ukraine (whether independent or not) was referred to as "the Ukraine". This is because in Russian, the word ukraina means 'borderland' so the definite article would be natural in the English language; this is similar to Nederlanden, which means 'low lands' and is rendered in English as "the Netherlands". However, since Ukraine's declaration of independence in 1991, this usage has become politicised and more rare, and style guides advise against its use. U.S. ambassador William Taylor said that using "the Ukraine" implies disregard for Ukrainian sovereignty. The official Ukrainian position is that "the Ukraine" is both grammatically and politically incorrect.
History
Early history
Evidence for the earliest securely dated hominin presence in Europe comes from 1.4 million-year-old stone tools from Korolevo, in western Ukraine. Settlement by modern humans in Ukraine and its vicinity dates back to 32,000 BC, with evidence of the Gravettian culture in the Crimean Mountains. By 4,500 BC, the Neolithic Cucuteni–Trypillia culture was flourishing in wide areas of modern Ukraine, including Trypillia and the entire Dnieper-Dniester region. Ukraine is a probable location for the first domestication of the horse. The Kurgan hypothesis places the Volga-Dnieper region of Ukraine and southern Russia as the linguistic homeland of the Proto-Indo-Europeans. Early Indo-European migrations from the Pontic steppes in the 3rd millennium BC spread Yamnaya Steppe pastoralist ancestry and Indo-European languages across large parts of Europe. During the Iron Age, the land was inhabited by Iranian-speaking Cimmerians, Scythians, and Sarmatians. Between 700 BC and 200 BC it was part of the Scythian kingdom.
From the 6th century BC, Greek, Roman, and Byzantine colonies were established on the north-eastern shore of the Black Sea, such as at Tyras, Olbia, and Chersonesus. These thrived into the 6th century AD. The Goths stayed in the area, but came under the sway of the Huns from the 370s. In the 7th century, the territory that is now eastern Ukraine was the centre 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.
In the 5th and 6th centuries, the Antes, which some relate as an early Slavic people, lived in Ukraine. Migrations from the territories of present-day Ukraine throughout the Balkans established many South Slavic nations. Northern migrations, reaching almost to Lake Ilmen, led to the emergence of the Ilmen Slavs and Krivichs. Following an Avar raid in 602 and the collapse of the Antes Union, most of these peoples survived as separate tribes until the beginning of the second millennium.
Golden Age of Kyiv
The establishment of the state of Kievan Rus' remains obscure and uncertain. The state included much of present-day Ukraine, Belarus and the western part of European Russia. According to the Primary Chronicle, the Rus' people initially consisted of Varangians from Scandinavia. In 882, the pagan Prince Oleg (Oleh) conquered Kyiv from Askold and Dir and proclaimed it as the new capital of the Rus'. Anti-Normanist historians however argue that the East Slavic tribes along the southern parts of the Dnieper River were already in the process of forming a state independently. The Varangian elite, including the ruling Rurik dynasty, later assimilated into the Slavic population. Kievan Rus' was composed of several principalities ruled by the interrelated Rurikid kniazes ("princes"), who often fought each other for possession of Kyiv.
During the 10th and 11th centuries, Kievan Rus' became the largest and most powerful state in Europe, a period known as its Golden Age. It began with the reign of Vladimir the Great (980–1015), who introduced Christianity. During the reign of his son, Yaroslav the Wise (1019–1054), Kievan Rus' reached the zenith of its cultural development and military power. The state soon fragmented as the relative importance of regional powers rose again. After a final resurgence under the rule of Vladimir II Monomakh (1113–1125) and his son Mstislav (1125–1132), Kievan Rus' finally disintegrated into separate principalities following Mstislav's death, though ownership of Kyiv would still carry great prestige for decades. In the 11th and 12th centuries, the nomadic confederacy of the Turkic-speaking Cumans and Kipchaks was the dominant force in the Pontic steppe north of the Black Sea.
The Mongol invasions in the mid-13th century devastated Kievan Rus'; following the Siege of Kyiv in 1240, the city was destroyed by the Mongols. In the western territories, the principalities of Halych and Volhynia had arisen earlier, and were merged to form the Principality of Galicia–Volhynia. Daniel of Galicia, son of Roman the Great, re-united much of south-western Rus', including Volhynia, Galicia, as well as Kyiv. He was subsequently crowned by a papal envoy as the first king of Galicia–Volhynia (also known as the Kingdom of Ruthenia) in 1253.
Foreign domination
In 1349, in the aftermath of the Galicia–Volhynia Wars, the region was partitioned between the Kingdom of Poland and the Grand Duchy of Lithuania. From the mid-13th century to the late 1400s, the Republic of Genoa founded numerous colonies on the northern coast of the Black Sea and transformed these into large commercial centres headed by the consul, a representative of the Republic. In 1430, the region of Podolia was incorporated into Poland, and the lands of modern-day Ukraine became increasingly settled by Poles. In 1441, Genghisid prince Haci I Giray founded the Crimean Khanate on the Crimean Peninsula and the surrounding steppes; the Khanate orchestrated Tatar slave raids. Over the next three centuries, the Crimean slave trade would enslave an estimated two million in the region.
In 1569, the Union of Lublin established the Polish–Lithuanian Commonwealth, and most of the Ukrainian lands were transferred from Lithuania to the Crown of the Kingdom of Poland, becoming de jure Polish territory. Under the pressures of Polonisation, many landed gentry of Ruthenia converted to Catholicism and joined the circles of the Polish nobility; others joined the newly created Ruthenian Uniate Church.
Cossack Hetmanate
Deprived of native protectors among the Ruthenian nobility, the peasants and townspeople began turning for protection to the emerging Zaporozhian Cossacks. In the mid-17th century, a Cossack military quasi-state, the Zaporozhian Host, was formed by Dnieper Cossacks and Ruthenian peasants. Poland exercised little real control over this population, but found the Cossacks to be useful against the Turks and Tatars, and at times the two were allies in military campaigns. However, the continued harsh enserfment of Ruthenian peasantry by Polish szlachta (many of whom were Polonised Ruthenian nobles) and the suppression of the Orthodox Church alienated the Cossacks. The latter did not shy from taking up arms against those they perceived as enemies and occupiers, including the Catholic Church with its local representatives.
In 1648, Bohdan Khmelnytsky led the largest of the Cossack uprisings against the Commonwealth and the Polish king, which enjoyed wide support from the local population. Khmelnytsky founded the Cossack Hetmanate, which existed until 1764 (some sources claim until 1782). After Khmelnytsky suffered a crushing defeat at the Battle of Berestechko in 1651, he turned to the Russian tsar for help. In 1654, Khmelnytsky was subject to the Pereiaslav Agreement, forming a military and political alliance with Russia that acknowledged loyalty to the Russian monarch.
After his death, the Hetmanate went through a devastating 30-year war amongst Russia, Poland, the Crimean Khanate, the Ottoman Empire, and Cossacks, known as "The Ruin" (1657–1686), for control of the Cossack Hetmanate. The Treaty of Perpetual Peace between Russia and Poland in 1686 divided the lands of the Cossack Hetmanate between them, reducing the portion over which Poland had claimed sovereignty to Ukraine west of the Dnieper river. In 1686, the Metropolitanate of Kyiv was annexed by the Moscow Patriarchate through a synodal letter of the Ecumenical Patriarch of Constantinople Dionysius IV, thus placing the Metropolitanate of Kyiv under the authority of Moscow. An attempt to reverse the decline was undertaken by Cossack Hetman Ivan Mazepa (1639–1709), who ultimately defected to the Swedes in the Great Northern War (1700–1721) in a bid to get rid of Russian dependence, but Hetmanate's capital city Baturyn was sacked (1708) and they were crushed in the Battle of Poltava (1709).
The Hetmanate's autonomy was severely restricted since Poltava. In the years 1764–1781, Catherine the Great incorporated much of Central Ukraine into the Russian Empire, abolishing the Cossack Hetmanate and the Zaporozhian Sich, and was one of the people responsible for the suppression of the last major Cossack uprising, the Koliivshchyna. After the annexation of Crimea by Russia in 1783, the newly acquired lands, now called Novorossiya, were opened up to settlement by Russians. The tsarist autocracy established a policy of Russification, suppressing the use of the Ukrainian language and curtailing the Ukrainian national identity. The western part of present-day Ukraine was subsequently split between Russia and Habsburg-ruled Austria after the fall of the Polish–Lithuanian Commonwealth in 1795.
19th and early 20th century
The 19th century saw the rise of Ukrainian nationalism. With growing urbanisation and modernisation 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 political theorist Mykhailo Drahomanov (1841–1895) led the growing nationalist movement. While conditions for its development in Austrian Galicia under the Habsburgs were relatively lenient, the Russian part (historically known as "Little Russia" or "South Russia") faced severe restrictions, going as far as banning virtually all books from being published in Ukrainian in 1876.
Ukraine, like the rest of the Russian Empire, joined the Industrial Revolution later than most of Western Europe due to the maintenance of serfdom until 1861. Other than near the newly discovered coal fields of the Donbas, and in some larger cities such as Odesa and Kyiv, Ukraine largely remained an agricultural and resource extraction economy. The Austrian part of Ukraine was particularly destitute, which forced hundreds of thousands of peasants into emigration, who created the backbone of an extensive Ukrainian diaspora in countries such as Canada, the United States and Brazil. Some of the Ukrainians settled in the Far East, too. According to the 1897 census, there were 223,000 ethnic Ukrainians in Siberia and 102,000 in Central Asia. An additional 1.6 million emigrated to the east in the ten years after the opening of the Trans-Siberian Railway in 1906. Far Eastern areas with an ethnic Ukrainian population became known as Green Ukraine.
Ukraine plunged into turmoil with the beginning of World War I, and fighting on Ukrainian soil persisted until late 1921. Initially, the Ukrainians were split between Austria-Hungary, fighting for the Central Powers, though the vast majority served in the Imperial Russian Army, which was part of the Triple Entente, under Russia. As the Russian Empire collapsed, the conflict evolved into the Ukrainian War of Independence, with Ukrainians fighting alongside, or against, the Red, White, Black and Green armies, with the Poles, Hungarians (in Transcarpathia), and Germans also intervening at various times.
