Founding: Independence from the Soviet Union — 24 August 1991. Modern Ukraine traces its statehood to 24 August 1991, when the Verkhovna Rada, Ukraine's parliament, adopted the Act of Independence amid the collapse of the Soviet Union following the failed August coup in Moscow. The declaration was overwhelmingly confirmed by a nationwide referendum on 1 December 1991, in which more than 90 percent of voters across every region endorsed independence; the Soviet Union was formally dissolved later that month. The deeper roots of Ukrainian statehood reach back over a thousand years to Kievan Rus', the medieval realm centred on Kyiv whose ruler Volodymyr the Great adopted Christianity in 988, and to the Cossack Hetmanate of the seventeenth century. The independence of 1991 restored a sovereign Ukrainian state after centuries in which Ukrainian lands had been divided among the Russian, Austrian and Polish-Lithuanian states and, in the twentieth century, ruled from Moscow.

Ukraine's history begins with Kievan Rus', the medieval federation centred on Kyiv that, under Volodymyr the Great, adopted Christianity from Byzantium in 988 and reached its height under Yaroslav the Wise. After the Mongol sack of Kyiv in 1240 the Rus' lands fragmented and were drawn into the orbits of Galicia-Volhynia, the Grand Duchy of Lithuania and Poland. From the steppe frontier rose the Cossacks and the Zaporozhian Sich, whose great uprising under Bohdan Khmelnytsky in 1648 created a Cossack Hetmanate that, by the 1654 Council of Pereiaslav, fell under Muscovite protection, dividing the Ukrainian lands between Russia and Poland and, after the partitions, between the Russian and Austrian empires. A modern national movement, voiced by the poet Taras Shevchenko, produced the short-lived Ukrainian People's Republic of 1917-1921, which was defeated and absorbed into Soviet Ukraine, where the man-made famine of 1932-33, the Holodomor, killed millions. After the devastation of the Second World War and the Holocaust on Ukrainian soil, Ukraine declared independence on 24 August 1991, confirmed by referendum on 1 December 1991, and gave up the world's third-largest nuclear arsenal under the 1994 Budapest Memorandum. Russia's annexation of Crimea in 2014 and its full-scale invasion of 2022, together with the purported annexation of four oblasts, have been condemned by the United Nations General Assembly as without legal validity.

## Kievan Rus' and the Baptism of 988 — c. 880 – 1240

## Between Lithuania, Poland and the Steppe — 1240 – 1648

After the fall of Kyiv the Rus' lands passed under Lithuanian and Polish rule, while on the southern frontier the Cossacks and the Zaporozhian Sich took shape.

- 14th century: **Rus' lands pass to Lithuania and Poland** — Following the collapse of Galicia-Volhynia, most of the former Rus' lands were absorbed by the Grand Duchy of Lithuania, while Galicia in the west passed to the Kingdom of Poland. [history-ukraine-britannica]
