Kazakhstan, officially the Republic of Kazakhstan (Қазақстан Республикасы), is a contiguous transcontinental country in Central Asia, with its smaller part west of the Ural River in Eastern Europe. Kazakhstan is the world’s largest landlocked country by land area and the ninth largest country in the world; its territory of 2,727,300 km² is larger than Western Europe.
It has borders with Russia, China, Kyrgyzstan, Uzbekistan, and Turkmenistan, and also adjoins a large part of the Caspian Sea. The terrain of Kazakhstan includes flatlands, steppe, taiga, rock canyons, hills, deltas, snow-capped mountains, and deserts. With 17 million people (2013 estimate) Kazakhstan has the 62nd largest population in the world, though its population density is less than 6 people per km².
The capital is Astana, where it was moved from Almaty in 1997.
The territory of Kazakhstan has historically been inhabited by nomadic tribes. This changed in the 13th century, when Genghis Khan occupied the country. When his ruling family fought for power, power generally switched back to the nomads. By the 16th century, the Kazakhs emerged as a distinct group, divided into three jüz (ancestor branches occupying specific territories).
The Russians began advancing into the Kazakh steppe in the 18th century, and by the mid-19th century all of Kazakhstan was part of the Russian Empire. Following the 1917 Russian Revolution, and subsequent civil war, the territory of Kazakhstan was reorganised several times before becoming the Kazakh Soviet Socialist Republic in 1936, a part of the Soviet Union.
Kazakhstan was the last of the Soviet republics to declare independence following the dissolution of the Soviet Union in 1991; the current President, Nursultan Nazarbayev, has been leader of the country since 1990.
Russia currently leases approximately 6,000 km² of territory enclosing the Baikonur Cosmodrome space launch site in south central Kazakhstan, where the first man was launched into space as well as Soviet space shuttle Buran and the well-known space station Mir.
