Ukraine emerged as the concept of a nation, and the Ukrainians as a nationality, with the Ukrainian National Revival which began in the late 18th and early 19th century. The first wave of national revival is traditionally connected with the publication of the first part of "Eneyida" by Ivan Kotlyarevsky (1798). In 1846, in Moscow the "Istoriya Rusov ili Maloi Rossii" (History of Ruthenians or Little Russia) was published. During the Spring of Nations, in 1848 in Lemberg (Lviv) the Supreme Ruthenian Council was created which declared that Galician Ruthenians were part of the bigger Ukrainian nation. The council adopted the yellow and blue flag, the current Ukrainian flag. Ukraine first declared its independence with the invasion of Bolsheviks in late 1917. Following the conclusion of World War I and with the Peace of Riga, Ukraine was partitioned once again between Poland and the Bolshevik Russia. The Bolshevik-occupied portion of the territory became the Ukrainian Soviet Socialist Republic, with some boundary adjustments. In 1922, the Ukrainian Soviet Socialist Republic, together with the Russian Soviet Federative Socialist Republic, the Byelorussian Soviet Socialist Republic and the Transcaucasian Socialist Federative Soviet Republic, became the founding members of the Soviet Union. The Soviet famine of 1932–33 or Holodomor killed an estimated 6 to 8 million people in the Soviet Union, the majority of them in Ukraine. In 1941, the Soviet Union was invaded by Germany and its other allies. Many Ukrainians initially regarded the Wehrmacht soldiers as liberators from Soviet rule, while others formed an anti-German partisan movement. Some elements of the Ukrainian nationalist underground formed a Ukrainian Insurgent Army that fought both Soviet and Nazi forces. In 1945, Ukraine was made one of the founding members of the United Nations even though it was part of the Soviet Union. In 1954 the Crimean Oblast was transferred from the RSFSR to the Ukrainian SSR. Following the dissolution of the Soviet Union at the end of the Cold War, Ukraine became an independent state, formalized with a referendum. With the enlargement of the European Union in 2004, Ukraine became an area of overlapping spheres of influence between the European Union and the Russian Federation. This manifested in a political division between the "pro-European" Western Ukraine and the "pro-Russian" Eastern Ukraine, which led to an ongoing series of political turmoil, including the Orange Revolution, the Euromaidan protests, and the Russian invasion.
