UKRAINE

Ukraine is a country in Eastern Europe. It has a unique ever-important geostrategic position between Europe and Asia, this position has been transformed into the role of one of Eurasia's key transportation nodes. Particularly, Ukraine is Europe's main and crucial gas- and oil-transiting country.
The historic city of Kiev (Kyiv) is the country's capital. From at least the ninth century, the territory of present-day Ukraine was a centre of medieval East Slavic civilization forming the state of Kievan Rus, and for the following several centuries the territory was divided between a number of regional powers. After a brief period of independence (1917–1921) following the Russian Revolution of 1917, Ukraine became one of the founding Soviet Republics in 1922. The Ukrainian Soviet Socialist Republic's territory was enlarged westward after the Second World War, and again in 1954 with the Crimea transfer. In 1945, Ukrainian SSR became one of the co-founder members of the United Nations. It became independent again after the Soviet Union's collapse in 1991.
