During Cold War

After the 1939 invasion of Poland by Nazi Germany and Soviet Union, the Ukrainian SSR's territory was enlarged westward. Ukraine was occupied by Nazi Germany from 1941 to 1944. During World War II the Ukrainian Insurgent Army fought for Ukrainian independence against both Germany and the Soviet Union. In 1945, the Ukrainian SSR became one of the founding members of the United Nations.[8] After Stalin's death, as head of the Communist Party of Soviet Union, Khrushchev enabled a Ukrainian revival. Nevertheless, there were further political repressions against poets, historians and other intellectuals, like in all other parts of the USSR. In 1954, the republic expanded to the south with the transfer of the Crimea.

Ukraine became independent again when the Soviet Union dissolved in 1991. This started a period of transition to a market economy, in which Ukraine suffered an eight-year recession.[9] Since then, however, the economy has experienced a high increase in GDP growth. Ukraine was caught up in the worldwide economic crisis in 2008 and the economy plunged. GDP fell 20% from spring 2008 to spring 2009, then leveled off.[10]
