Kazakhstan officially the Republic of Kazakhstan is a transcontinental country mainly located in Central Asia with a smaller portion west of the Ural River in Eastern Europe. It covers a land area of 2,724,900 square kilometres (1,052,100 sq mi), and shares land borders with Russia in the north, China in the east, and Kyrgyzstan, Uzbekistan, and Turkmenistan in the south while also adjoining a large part of the Caspian Sea in the southwest. Kazakhstan does not border Mongolia, although they are only 37 kilometers apart.
The territory of Kazakhstan has historically been inhabited by nomadic groups and empires. In antiquity, the nomadic Scythians inhabited the land and the Persian Achaemenid Empire expanded towards the southern territory of the modern country. Turkic nomads, who trace their ancestry to many Turkic states such as the First and Second Turkic Khaganates, have inhabited the country throughout its history. In the 13th century, the territory was subjugated by the Mongol Empire under Genghis Khan. By the 16th century, the Kazakh emerged as a distinct group, divided into three jüz. The Russians began advancing into the Kazakh steppe in the 18th century, and by the mid-19th century, they nominally ruled all of Kazakhstan as part of the Russian Empire. Following the 1917 Russian Revolution, and subsequent civil war, the territory of Kazakhstan was reorganised several times. In 1936, it was made the Kazakh Soviet Socialist Republic, part of the Soviet Union. Kazakhstan was the last of the Soviet republics to declare independence during the dissolution of the Soviet Union in 1991. The first president of Kazakhstan was characterised as an authoritarian, and his government was accused of numerous human rights violations, including suppression of dissent and censorship of the media. Human Rights Watch says that "Kazakhstan heavily restricts freedom of assembly, speech, and religion." Other human rights organisations regularly describe Kazakhstan's human rights situation as poor.
Kazakhstan is the most dominant nation of Central Asia economically, generating 60% of the region's GDP, primarily through its oil and gas industry. It also has vast mineral resources, and is officially a democratic, secular, unitary, constitutional republic with a diverse cultural heritage. Kazakhstan is a member of the United Nations (UN), WTO, CIS, the Shanghai Cooperation Organization (SCO), the Eurasian Economic Union, CSTO, OSCE, OIC, CCTS, the Turkic Council and TURKSOY.
