The Kazakh Soviet Socialist Republic, also known as Soviet Kazakhstan, the Kazakh SSR, KSSR, or simply Kazakhstan, was one of the constituent republics of the Soviet Union (USSR) from 1936 to 1991. Being located in northern Central Asia, the Kazakh SSR was created on 5 December 1936 from the erstwhile Kazakh ASSR, which was an autonomous republic of the Russian SFSR. It shared borders with its fellow Soviet republics of Russia, Kyrgyzstan, Turkmenistan and Uzbekistan, while also sharing an international border with the People's Republic of China.
At 2,717,300 square kilometres (1,049,200 sq mi) in area, it was the second-largest republic in the USSR, after the Russian SFSR. Its capital was Alma-Ata (today known as Almaty). During its existence as a Soviet Socialist Republic, it was ruled by the Communist Party of the Kazakh SSR (QKP). It was the most economically advanced of the central Asian Soviet Republics, having a significant base in mineral extraction and agriculture.
