It declared itself a neutral state, forming a limited military partnership with Russia and other CIS countries while also establishing a partnership with NATO in 1994. Since its independence, Ukraine has been governed as a unitary republic under a semi-presidential system.

With the dissolution of the Soviet Union Ukraine regained its independence in 1991. Ukraine was the most populous and industrialised republic after the Russian Soviet Republic. In 1939, Western Ukraine was annexed from Poland by the USSR. From 1932 to 1933 the Holodomor killed millions of Ukrainians. This short-lived state was forcibly reconstituted into the Ukrainian Soviet Socialist Republic, which became a founding member of the Soviet Union (USSR) in 1922. In the aftermath of the Russian Revolution a Ukrainian national movement re-emerged, and the Ukrainian People's Republic was formed in 1917. The Cossack Hetmanate emerged in Central Ukraine in the 17th century but was partitioned between Russia and Poland, and ultimately completely absorbed by the Russian Empire. Over the next 600 years, the area was contested, divided, and ruled by external powers, including the Polish–Lithuanian Commonwealth, the Austrian Empire, Austria-Hungary, the Ottoman Empire, and the Tsardom of Russia. During the Middle Ages, the area was a key centre of East Slavic culture under Kievan Rus', which was ultimately destroyed by the Mongol invasion in the 13th century. The territory of modern Ukraine has been inhabited since 32,000 BC. The nation's capital and largest city is Kyiv. It covers about 600,000 km 2 (230,000 sq mi), with a population of about 40 million. Ukraine also shares borders with Belarus to the north Poland, Slovakia, and Hungary to the west Romania and Moldova to the south and has a coastline along the Sea of Azov and the Black Sea. It is the second largest country in Europe after Russia, which borders it to the east and north-east. Ukraine ( Ukrainian: Україна, romanized: Ukraïna, pronounced ( listen)) is a country in Eastern Europe.
