Historically Ukraine was inhabited by pagan tribes, but Byzantine rite Christianity was introduced by the turn of the first millennium. It was imagined by later writers who sought to put Kievan Christianity on the same level of primacy as Byzantine Christianity that Apostle Andrew himself had visited the site where the city of Kiev would be later built.

However it was only by the 10th century that the emerging state, the Kievan Rus' became influenced by the Byzantine Empire, the first known conversion was by the Princess Saint Olga who came to Constantinople in 945 or 957. Several years later, her grandson, Knyaz Vladimir baptised his people in the Dnieper River. This began a long history of the dominance of the Eastern Orthodoxy in Ruthenia that later was to influence Russia and Ukraine.

Judaism was present on Ukrainian lands for approximately 2000 years when Jewish traders appeared in Greek colonies. At the same time the neighbouring Khazar Kaganate was influenced by Judaism. Since the 13th century the Jewish presence in Ukraine increased significantly. Later on in Ukraine was established new teaching of Judaism - Hasidism.

Ukraine (ⁱ/juːˈkreɪn/ yew-KRAYN; Ukrainian: Україна, transliterated: Ukrayina, [ukrɑˈjinɑ]; Russian: Украина; Crimean Tatar: Ukraina) is a country in Central and Eastern Europe. Ukraine borders the Russian Federation to the east and northeast, Belarus to the northwest, Poland, Slovakia and Hungary to the west, Romania and Moldova to the southwest, and the Black Sea and Sea of Azov to the south and southeast, respectively. It has an area of 603,628 km², making it the second largest contiguous country on the European continent, after the Russian Federation.

According to a popular and well established theory, the medieval state of Kievan Rus was established by the Varangians in the 9th century as the first historically recorded East Slavic state which emerged as a powerful nation in the Middle Ages until it disintegrated in the 12th century. By the middle of the 14th century, Ukrainian territories were under the rule of three external powers—the Golden Horde, the Grand Duchy of Lithuania, and the Kingdom of Poland. After the Great Northern War (1700–1721) Ukraine was divided between a number of regional powers and, by the 19th century, the largest part of Ukraine was integrated into the Russian Empire with the rest under Austro-Hungarian control. A chaotic period of incessant warfare ensued, with several internationally recognized attempts at independence from 1917 to 1921, following World War I and the Russian Civil War. Ukraine emerged from its own civil war, and on December 30, 1922 Ukrainian Soviet Socialist Republic became one of the founding republics of the Soviet Union. The Ukrainian SSR's territory was enlarged westward during the civil war shortly before, and after World War II, and further south in 1954 with the Crimea transfer. In 1945, the Ukrainian SSR became one of the founding members of the United Nations.

Vladimir Vladimirovich Putin (Russian: Влади́мир Влади́мирович Пу́тин; IPA: [vɫɐˈdʲimʲɪr vɫɐˈdʲimʲɪrəvʲɪtɕ ˈputʲɪn] ( listen); born 7 October 1952) is a Russian politician who has been the President of Russia since 7 May 2012. Putin previously served as President from 2000 to 2008 and as Prime Minister of Russia from 1999 to 2000, and again from 2008 to 2012. Putin also serves as chairman of United Russia and Chairman of the Council of Ministers of the Union of Russia and Belarus. He became acting President on 31 December 1999, when president Boris Yeltsin resigned in a surprising move. Putin won the 2000 presidential election; in 2004 he was re-elected for a second term lasting until 7 May 2008.

Because of constitutionally mandated term limits, Putin was ineligible to run for a third consecutive presidential term. After his successor Dmitry Medvedev won the 2008 presidential election, Putin was nominated by Medvedev to be Russia's Prime Minister; Putin took office on 8 May 2008 and a period of so-called "tandemocracy" followed. In September 2011, Putin and Medvedev agreed he should seek a third, non-consecutive term in the 2012 presidential election, which he won in the first round on 4 March 2012.
