🇺🇦 Ukraine

Settlement by modern humans in Ukraine and its vicinity dates back to 32,000 BC, evidenced by Gravettian remains in the Crimean Mountains. Far earlier hominin presence is attested by 1.4 million-year-old stone tools at Korolevo in western Ukraine, the earliest securely dated in Europe.

By 4,500 BC the Neolithic Cucuteni–Trypillia culture flourished across the Dnieper-Dniester region. Ukraine is also a probable location for the first domestication of the horse, and the Volga-Dnieper region is placed by the Kurgan hypothesis as the Proto-Indo-European homeland.

During the Iron Age the land was inhabited by Iranian-speaking Cimmerians, Scythians and Sarmatians. Between 700 BC and 200 BC it formed part of the Scythian kingdom.

From the 6th century BC colonies were established on the north-eastern shore of the Black Sea, thriving into the 6th century AD. They linked the region to Mediterranean trade and civilisation for over a millennium.

The Goths remained in the area but fell under the domination of the Huns from the 370s. The episode marked the region's absorption into the wider migration-period upheavals of the steppe.

In the 7th century the territory of eastern Ukraine was the centre of Old Great Bulgaria. At the end of the century most Bulgar tribes migrated away and the Khazars took over much of the land.

In the 5th and 6th centuries the Antes, related by some to early Slavs, lived in Ukraine, and migrations from these territories established many South Slavic nations and northern groups such as 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 into the second millennium.

In 882 the pagan Prince Oleg took Kyiv from Askold and Dir and made it the new capital of the Rus'. The event is conventionally taken as the founding of Kievan Rus', the state that would encompass much of present-day Ukraine, Belarus and western European Russia.

Ukraine was the centre of the first eastern Slavic state, Kyivan Rus, which during the 10th and 11th centuries was the largest and most powerful state in Europe. Weakened by internecine quarrels and Mongol invasions, it was incorporated into the Grand Duchy of Lithuania and eventually the Polish–Lithuanian Commonwealth, while its cultural and religious legacy laid the foundation for Ukrainian nationalism through subsequent centuries.

The reign of Vladimir the Great began the Golden Age of Kievan Rus' and brought Christianisation. Old Church Slavonic became the liturgical and literary language, laying the foundations of Ukrainian literature.

The mass baptism in the Dnieper river tied the state to Byzantine Christianity and shaped the religious and cultural development of the wider region for centuries afterwards.

Under Yaroslav the Wise, Kievan Rus' reached the height of its cultural development and military strength, standing as the largest and most powerful state in Europe. The state fragmented thereafter as regional powers rose.

A final resurgence under Vladimir II Monomakh (1113–1125) and his son Mstislav (1125–1132) was followed by definitive fragmentation. Ownership of Kyiv retained great prestige for decades, but unified rule was lost.

Genoa established numerous colonies on the northern Black Sea coast and turned them into large commercial centres headed by consuls. They integrated the region into Mediterranean long-distance trade networks.

The destruction of the city in December 1240 marked the effective end of Kyivan Rus as a unified power, ushering in centuries of fragmented rule by neighbouring states.

Daniel re-united much of south-western Rus', including Volhynia, Galicia and Kyiv, and was crowned king of Galicia–Volhynia, also known as the Kingdom of Ruthenia. The kingdom preserved a Rus' successor state in the west after the Mongol destruction.

In 1349 the lands of Galicia–Volhynia were divided between the Kingdom of Poland and the Grand Duchy of Lithuania. This began centuries of foreign domination over the Ukrainian lands.

In 1430 the region of Podolia was incorporated into Poland. The lands of modern-day Ukraine became increasingly settled by Poles, deepening Polish political and social influence.

The Genghisid prince established the Khanate over Crimea and the surrounding steppes. The Khanate orchestrated Tatar slave raids, and over three centuries the Crimean slave trade enslaved an estimated two million people in the region.

Most Ukrainian lands passed from Lithuania to the Crown of the Kingdom of Poland, becoming de jure Polish territory. Under Polonisation pressures much of the Ruthenian gentry converted to Catholicism or joined the new Ruthenian Uniate Church, depriving the peasantry of native protectors.

Peasants and townspeople deprived of native protectors turned to the emerging Zaporozhian Cossacks for protection. Poland exercised little real control over them but used them against the Turks and Tatars, while enserfment and suppression of Orthodoxy drove Cossack alienation.

Bohdan Khmelnytsky led the largest Cossack uprising against the Polish-Lithuanian Commonwealth and its king, a revolt that enjoyed wide popular support and established the Cossack Hetmanate. The Cossack state lasted, with fluctuating autonomy, until 1764 and is regarded as the foundational early-modern Ukrainian polity and a foundation of modern Ukrainian statehood.

After his crushing defeat at Berestechko in 1651 Khmelnytsky turned to Russia for help, concluding a military and political alliance that acknowledged loyalty to the Russian monarch. The agreement began the long subordination of Ukrainian lands to Moscow.

After Khmelnytsky's death the Hetmanate was devastated by a thirty-year struggle for its control. The conflict shattered the young Cossack state's cohesion and invited permanent foreign intervention.

The 1686 treaty partitioned the lands of the Cossack Hetmanate, reducing Poland's claimed sovereignty to Ukraine west of the Dnieper. The Dnieper partition entrenched the east–west division of Ukrainian lands.

A synodal letter annexed the Metropolitanate of Kyiv to Moscow, subordinating Ukrainian Orthodoxy to Russian ecclesiastical authority. The decision was reversed only in 2019 with recognition of the Orthodox Church of Ukraine.

Mazepa sought to escape Russian dependence during the Great Northern War, but the Hetmanate's capital Baturyn was sacked in 1708 and his forces were destroyed at Poltava in 1709. The Hetmanate's autonomy was severely restricted thereafter.

Catherine dissolved the Hetmanate and the Zaporozhian Sich and absorbed much of Central Ukraine, suppressing the Koliivshchyna, the last major Cossack uprising. Ukrainian self-government was extinguished for over a century.

After the annexation the newly acquired lands, named Novorossiya, were opened to settlement by Russians. Tsarist autocracy also imposed Russification, suppressing the Ukrainian language and curtailing national identity.

With the Commonwealth's collapse, the western part of present-day Ukraine was divided between the Russian and Austrian empires. The division produced sharply differing conditions for Ukrainian national development in Galicia and in Russian-ruled 'Little Russia'.

The publication began the modern era of Ukrainian literary tradition after the modern literary language emerged in the late 18th century. It underpinned the romantic literature of the 1830s and the nineteenth-century national revival.

Higher education expanded with universities in Kharkiv (1805), Kyiv (1834), Odesa (1865) and Chernivtsi (1875), followed by professional institutes including a Veterinary Institute (1873) and Technological Institute (1885) in Kharkiv, a Kyiv Polytechnic (1898) and a Higher Mining School (1899) in Katerynoslav. By 1988 there were 146 higher education institutions with over 850,000 students.

Ukraine joined the Industrial Revolution later than most of Western Europe because serfdom persisted until 1861. Outside the newly discovered Donbas coalfields and cities such as Odesa and Kyiv, the economy remained agricultural and extractive.

The use of the Ukrainian language in print was banned in 1863, with restrictions extended in 1876 to bar virtually all books published in Ukrainian. The bans sought to suppress the emerging national movement led by figures such as Taras Shevchenko and Mykhailo Drahomanov.

Poverty in Austrian-ruled Ukraine forced hundreds of thousands of peasants abroad, forming the backbone of a diaspora in Canada, the United States and Brazil. The 1897 census recorded 223,000 ethnic Ukrainians in Siberia and 102,000 in Central Asia.

An additional 1.6 million Ukrainians emigrated eastwards in the ten years after the railway opened in 1906. Far Eastern areas with an ethnic Ukrainian population became known as Green Ukraine.

Ukrainians were split between Austria-Hungary's forces and the Imperial Russian Army, and fighting on Ukrainian soil persisted until late 1921. As the Russian Empire collapsed the conflict evolved into the Ukrainian War of Independence involving Red, White, Black and Green armies plus Polish, Hungarian and German intervention.

Following the Russian Revolution and the collapse of tsarist Russia, Mykhailo Hrushevsky announced the left-leaning Ukrainian People's Republic as an attempt at an independent state, with independence first declared on 22 January 1918 and the short-lived Western and Greater Ukrainian republics uniting a year later. The UPR was deposed by Pavlo Skoropadskyi's coup creating the German-protected Ukrainian State, and the Directorate's restoration attempt failed as the army was repeatedly overrun before the Bolsheviks reconquered Ukraine by 1920.

During the 1920s a national renaissance in Ukrainian culture and language was encouraged as part of the Soviet-wide indigenisation policy. It attracted prominent former UNR figures, including Hrushevsky, to return to Soviet Ukraine, even as arrests and deportations of Ukrainian intellectuals began in July 1922.

The NEP introduced a form of market socialism permitting private ownership of small and medium enterprises to rebuild an economy shattered by war. It restored pre-WWI production and agricultural output by the mid-1920s, much of the latter based in Ukraine.

Stalin abolished the NEP and imposed a centrally planned economy. Soviet Ukraine took part in an industrialisation scheme that quadrupled its industrial output during the 1930s.

After reconquering Ukraine, the Soviet regime imposed brutal rule that engineered forced famines in 1921–22 and 1932–33 – the latter known as the Holodomor – in which over 8 million people died.

After the wars, Soviet forces dislodged the remaining factions and Soviet Ukraine became a founding republic of the Soviet Union in 1922, while Poland annexed the western provinces, Romania took Bukovina and Carpathian Ruthenia joined Czechoslovakia. The fighting left over 1.5 million dead across the former empire, with famine striking eastern provinces in 1921.

The Great Purge killed a new generation of Ukrainian intellectuals, a loss known as the Executed Renaissance, with around 223 writers repressed. It compounded the demographic catastrophe of the famine and gutted national cultural leadership.

Stalin's collectivisation under the first five-year plan, enforced by troops and the secret police with resisters deported to gulags, caused the man-made famine known as the Holodomor: collective farm members were denied grain until unrealistic quotas were met and millions starved. Estimates of the death toll vary widely, from around 3.5 million to more than 5 million, and the famine is recognised by many countries as an act of genocide against the Ukrainian people.

The decree 'On the Reconstruction of Literary and Art Organisations' imposed socialist realism on artists and writers. Creative freedom was only restored with glasnost in the 1980s.

Marshal Józef Piłsudski had sought Ukrainian support by offering local autonomy in the Kresy region to limit Soviet influence. After his death the approach was dropped amid OUN assassinations of Polish officials, and Warsaw restricted the rights of those declaring Ukrainian nationality, widening support for the nationalist underground.

German and Soviet troops divided Poland, and the Ukrainian-populated territories of Eastern Galicia and Volhynia became part of Soviet Ukraine. For the first time in history the nation was territorially united.

The USSR forced Romania to cede northern and southern Bessarabia, Northern Bukovina and the Hertsa region, which were incorporated into Soviet Ukraine, while the western Moldavian ASSR was handed to the new Moldavian SSR. These gains were internationally recognised by the Paris peace treaties of 1947.

The Second World War brought catastrophic losses to Ukraine at the hands of both German and Soviet forces, with estimates of total losses to the Ukrainian population ranging from around 6 million to 7–8 million dead. Some 1.5 million Jews were killed by the Einsatzgruppen, and of the 4.5 to 7 million ethnic Ukrainians who fought in the Soviet Army, 1.4 million died.

The Axis advance overwhelmed the Red Army; at the battle of Kyiv over 600,000 Soviet soldiers were killed or captured and the city was later acclaimed a Hero City. Most of the Ukrainian SSR was organised as Reichskommissariat Ukraine, subjected to genocidal policies, mass deportation for labour and a depopulation programme.

The 19 June move followed Zelenskyy's decision to name a special forces unit after the Ukrainian Insurgent Army, which Poland holds responsible for wartime massacres of Poles in Volhynia, straining relations between the two allies.

The tribunal, established to prosecute the political and military leadership responsible for ordering Russia's invasion, marked a significant step in international efforts to hold Moscow legally accountable for the war.

The 24 May strike destroyed the Ukrainian National Chernobyl Museum and damaged the National Art Museum of Ukraine, among other targets across the city.

The funding, politically agreed in December 2025 to cover Ukraine's financing needs through 2027, was finalised alongside new sanctions on Russia after member states failed to agree on using frozen Russian assets instead.

The deployment, made amid the 2026 Iran war, drew on Ukraine's battlefield experience countering drone attacks and marked an unusual extension of its military cooperation with Washington beyond its own territory.

The 1 February move, which exempted terminals pre-approved by Ukraine's defence ministry, followed evidence that Russian forces were using the satellite internet service in military operations.

Both countries cited attacks on the Druzhba pipeline, which carries Russian oil through their territory, in a dispute that further strained relations with Kyiv over energy transit.

The 9 January resignations came days after the head of the Security Service of Ukraine also stepped down, amid a broader reshuffle of the wartime government.

Yermak quit on 28 November after anti-corruption investigators raided his apartment over the Energoatom scandal, a bribery case involving the state nuclear firm that had already forced two ministers to resign.

The 7 September attack damaged the seat of Ukraine's government, one of a continuing series of Russian strikes on the capital during the war.

Parliament permitted Ukrainians to hold more than one nationality. The change addresses the status of a large wartime diaspora and historic emigrant communities.

The dam's destruction added to environmental damage from the 2022 invasion that has been described as an ecocide. It compounded existing problems of air and water pollution, deforestation and Chernobyl radiation contamination.

Several deputy ministers and regional heads resigned during a government reshuffle in early 2023. Corruption remains an obstacle to EU accession, with Ukraine rated 104th of 181 in the 2025 Corruption Perceptions Index.

After President Zelenskyy requested immediate admission amid the full-scale war, Ukraine received candidate status on 23 June 2022. Ukraine also applied to join NATO in 2022, transforming its accession timetable from a planned 2024 application.

Russia launched a full-scale invasion of Ukraine on 24 February 2022, ending the frozen conflict and opening the largest war in Europe since 1945; martial law was declared and remains in force, and the assault triggered mass civilian displacement and sweeping international sanctions against Russia. A year later Russian troops controlled about 17% of Ukraine's internationally recognised territory, including 94% of Luhansk Oblast and all of Crimea, though Ukrainian counteroffensives recaptured some ground and US officials estimated in August 2023 that up to 70,000 Ukrainian soldiers had been killed.

Over 4.1 million fled the country in early 2022, on top of 1.4 million internally displaced by the Donbas war in the late 2010s. Government estimates put the population in Ukrainian-controlled regions at 25 to 27 million in 2024, down from a 1993 peak of roughly 52 million.

The IMF expected the economy to contract sharply in 2022 despite emergency financial support, with post-war reconstruction estimated at up to half a trillion dollars. Ukraine had been the sixth largest wheat exporter and supplied about half of world sunflower oil exports in 2020/21, so the decline endangered global food security.

In early 2022 the two countries disconnected from the Integrated Power System of Russia and Belarus, and ENTSO-E synchronised them with continental Europe. The switch removed a critical infrastructural dependency on Moscow.

The foreign ministers signed a joint memorandum establishing the trio of EU association countries. It coordinated their push for European integration.

The pandemic arrived in 2020 and efforts to combat it were hampered by low vaccination uptake. Later in the pandemic the response was further undermined by the Russian invasion.

The three states formed the initiative in Lublin to deepen cooperation among the historic countries of the Polish–Lithuanian Commonwealth. It aims to advance Ukraine's integration and accession to the EU and NATO.

On 7 February 2019 parliament voted to write accession to the European Union and NATO into the constitution. The amendment locked Ukraine's Western orientation into its founding law.

Recognition reversed the 1686 decision of the patriarch of Constantinople subordinating the Metropolitanate of Kyiv to Moscow. It dealt a further blow to Russian influence in Ukraine.

The law prohibits primary education in public schools in grade five and up in any language other than Ukrainian. It formed part of the linguistic consolidation following the outbreak of war with Russia.

The DCFTA entered into force following ratification of the Association Agreement. It formally integrates Ukraine into the European Single Market and the European Economic Area.

Mass protests known as the Euromaidan, begun in winter 2013 against Yanukovych's refusal to sign the EU Association Agreement, culminated in violent clashes that left more than 100 protesters dead; on 21 February 2014 he fled to Russia and parliament removed him in what became known as the Revolution of Dignity. Russia refused to recognise the interim pro-Western government, denouncing the events as a US-sponsored coup.

Following the Revolution of Dignity parliament voted to repeal the 2012 law permitting official use of minority languages where a 10 per cent minority spoke them, making Ukrainian the sole state language at all levels. The repeal was not signed by acting President Turchynov or President Poroshenko, but the regional languages law was found unconstitutional in 2019.

The agreement was signed in June 2014 shortly after Yanukovych fled, marking a decisive Western reorientation. Ukrainians were granted visa-free travel to the EU three years later.

In late February and early March 2014, immediately after the Euromaidan revolution, Russian forces seized Crimea using the Sevastopol naval base and unmarked 'little green men', annexing the peninsula after an unrecognised referendum in a move condemned as illegal by the UN General Assembly and most of the international community. Russia then fostered the breakaway Donetsk and Luhansk People's Republics and began an open invasion of the Donbas on 24 August 2014, pushing Ukrainian troops back to the frontline fixed in February 2015 after the withdrawal from Debaltseve.

The October 2012 Rada elections were widely criticised by Western observers as flawed, citing the use of government resources to favour ruling-party candidates, interference with media access and harassment of opposition candidates.

Internal squabbles in the Yushchenko camp allowed his rival Viktor Yanukovych to stage a comeback in parliamentary elections, become prime minister in August 2006, and win the presidency in February 2010.

Primary education takes four years from age six, middle secondary five years and upper secondary three. The reform aligned Ukrainian schooling with European norms.

A peaceful mass protest in the closing months of 2004 forced the authorities to overturn a rigged presidential election and allow a new internationally monitored vote that swept into power a reformist slate under Viktor Yushchenko.

A Ukrainian unit served in Iraq under Polish command. The deployment signalled Kyiv's willingness to contribute to Western-led coalition operations.

In the 2000s the government leaned towards NATO and deepened cooperation through the 2002 Action Plan. At the 2008 Bucharest summit NATO declared Ukraine would eventually become a member once it met accession criteria.

The PCA entered into force in 1998, with the EU urging full implementation before association talks. The December 1999 Helsinki EU Summit recognised Ukraine's long-term aspirations without discussing association.

The constitution was ratified on 28 June 1996 with 315 of 450 votes, against a required minimum of 300. Constitution Day has been celebrated on 28 June since, and the document framed Ukraine's transition to a free market liberal democracy.

Ukraine agreed to hand over its nuclear weapons in exchange for guarantees of security and territorial integrity. The guarantees proved worthless when Russia annexed Crimea and launched war in 2014. Ukraine also began a partnership with NATO in 1994.

In 1992 Ukraine joined the Conference on Security and Cooperation in Europe, now the OSCE, and the North Atlantic Cooperation Council. It also began contributing to UN peacekeeping operations that year.

Ukraine inherited a 780,000-strong military and the world's third-largest nuclear arsenal at the Soviet collapse. Under the Lisbon Protocol it agreed to transfer all nuclear weapons to Russia and join the NPT as a non-nuclear state, becoming free of nuclear weapons by 1996.

The transition to a market economy produced a deeper slowdown than in almost any other former Soviet republic, with hyperinflation peaking in 1993. Mass privatisation created the oligarch class, and the new hryvnia currency fell sharply in late 1998 after Russia's debt default.

Independence was proclaimed on 24 August 1991 after the failed Moscow coup and approved by 92% of voters on 1 December. President Leonid Kravchuk signed the Belavezha Accords and made Ukraine a founding member of the CIS, though it never ratified the founding agreement; the USSR voted itself out of existence on 26 December.

On 16 July 1990, as part of the parade of sovereignties, the newly elected parliament declared state sovereignty. It was the decisive constitutional step preceding full independence.

The 26 April accident forced the evacuation of the nearby city of Pripyat and spread radioactive fallout across much of Europe, with long-term health and environmental consequences still debated.

Brezhnev served as General Secretary of the Communist Party of the Soviet Union from 1964 to 1982 while his appointee Shcherbytsky governed Ukraine. Both were instrumental in Russification and in repressing the Sixtiers generation of Ukrainian intellectuals.

Soviet leader Nikita Khrushchev oversaw the transfer of Crimea from the Russian SFSR to the Ukrainian SSR, presented as a friendship gift marking the 300th anniversary of a 17th-century Russo-Ukrainian treaty and justified on economic grounds, following Stalin's death in 1953 and the onset of de-Stalinisation. The administrative transfer had little practical effect at the time but was the final extension of Ukrainian territory, forming the basis of Ukraine's internationally recognised borders and becoming a central point of dispute after independence.

By 1950 the republic had fully recovered its industrial output and soon became a European leader in industrial production. It was an important centre of the Soviet arms industry and high-tech research, though heavy industry retained outsized influence.

More than 700 cities and towns and 28,000 villages had been destroyed by the war, and a drought-driven famine in 1946–1947 killed at least tens of thousands. Post-war population transfers, including forced deportation of Germans and Crimean Tatars, homogenised the population.

Under a special agreement reached at the Yalta Conference, Soviet Ukraine joined the UN in 1945 with its own voting rights despite not being independent. Ukraine also annexed Zakarpattia and later served as a non-permanent Security Council member from 1999 to 2001.

The UPA arose in Western Ukraine as the armed force of the OUN underground, seeking an independent Ukrainian state on ethnically Ukrainian territory. From mid-1943 it carried out massacres of around 100,000 Polish civilians in Volhynia and Eastern Galicia, and continued fighting the USSR until the 1950s.
