Ukraine ( , transliterated: lang: Ukrayina, ) is a country in Eastern Europe. It is bordered by Russia to the east; Belarus to the north; Poland, Slovakia, and Hungary to the west; Romania and Moldova to the southwest; and the Black Sea and Sea of Azov to the south. The city of Kiev (lang: Kyiv) is both the capital and the largest city of Ukraine.

Ukraine's modern history began with the East Slavs. From at least the 9th century, Ukraine was a center of the medieval East Slavic civilization. This state, known as Kievan Rus' became the largest and most powerful nation in Europe, but disintegrated in the 12th century. Ukraine was the home of the first modern democracy, which exhibited republican form, during the Khmelnytsky uprising in the 17th century. After the Great Northern War, Ukraine was divided among 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. After a chaotic period of incessant warfare and several attempts at independence (1917–21) following World War I and the Russian Civil War, Ukraine emerged in 1922 as one of the founding republics of the Soviet Union. The Ukrainian Soviet Socialist Republic's territory was enlarged westward shortly before and after World War II, and again in 1954 with the Crimea transfer. In 1945, the Ukrainian SSR became one of the co-founding members of the United Nations. Ukraine became independent again after the dissolution of the Soviet Union in 1991. This began a period of transition to a market economy, in which Ukraine was stricken with an eight year recession. But since then, the economy has been experiencing a stable increase with GDP growth averaging 24 percent annually.

Ukraine is a unitary state composed of 24 oblasts (provinces), one autonomous republic (Crimea), and two cities with special status: Kiev, its capital, and Sevastopol, which houses the Russian Black Sea Fleet under a leasing agreement. Ukraine is a republic under a semi-presidential system with separate legislative, executive, and judicial branches. Since the collapse of the USSR, Ukraine continues to maintain the second largest military in Europe, after that of Russia. The country is home to 46.2 million people, 77.8 percent of whom are ethnic Ukrainians, with sizable minorities of Russians, Belarusians and Romanians. The Ukrainian language is the only official language in Ukraine, while Russian is also widely spoken. The dominant religion in the country is Eastern Orthodox Christianity, which has heavily influenced Ukrainian architecture, literature and music.

History

Early history

Human settlement in the territory of Ukraine dates back to at least 4500 BC, when the Neolithic Cucuteni culture flourished in a wide area that covered parts of modern Ukraine including Trypillia and the entire Dnieper-Dniester region. During the Iron Age, the land was inhabited by Cimmerians, Scythians, and Sarmatians. Between 700 BC and 200 BC it was part of the Scythian Kingdom, or Scythia. Later, colonies of Ancient Greece, Ancient Rome, and the Byzantine Empire, such as Tyras, Olbia, and Hermonassa, were founded, beginning in the 6th century BC, on the northeastern shore of the Black Sea, and thrived well into the 6th century AD. The Goths stayed in the area but came under the sway of the Huns from the 370s AD. In the 7th century AD, the territory of eastern Ukraine was the center of Old Great Bulgaria. At the end of the century, the majority of Bulgar tribes migrated in different directions and the land fell into the Khazars' hands.
