Established on 26 August 1920, it was initially called
Kirghiz ASSR (
Kirghiz Autonomous Soviet Socialist Republic) and was a part of the
Russian SFSR. On 15–19 April 1925, it was renamed
Kazak ASSR (subsequently
Kazakh ASSR) and on 5 December 1936 it was elevated to the status of a Union-level republic,
Kazakh Soviet Socialist Republic. In September 1920, the Ninth Soviet Congress of Turkestan called for the deportation of illegal settler colonists in the Northern parts of the country. The proposed land reform began in 1921 and lasted until 1927, targeting Russian settlers, Ukrainians and Cossacks in the region and from 1920 to 1922, Kazakhstan's Russian population dropped from approximately 2.7 to 2.2 million. On 19 February 1925,
Filipp Goloshchyokin was appointed First Secretary of the Communist Party in the newly created Kazakh Autonomous Socialist Soviet Republic. From 1925 to 1933 he ran the Kazakh ASSR with an iron grip, surprisingly with virtually zero interference from Moscow. He played a prominent part in the construction of the Turkestan-Siberia railway, which was constructed to open up Kazakhstan's mineral wealth. After
Joseph Stalin ordered the forced collectivization of agriculture throughout the Soviet Union, Goloshchyokin ordered that Kazakhstan's largely nomadic population was to be settled in collectivized farms. This, alongside the disastrous agricultural and scientific policies of
Trofim Lysenko, eventually culminated in the deadly
Kazakh famine of 1930–1933 in Kazakhstan which killed between 1 and 2 million people. Kazakhstani Korean scholar
German Kim assumes that one of the reasons for this deportation may have been Stalin's intent to oppress ethnic minorities that could have posed a threat to his socialist system or he may have intended to consolidate the border regions with
China and Japan by using them as political bargaining chips. Additionally, historian Kim points out that 1.7 million people perished in the
Kazakh famine of 1931–1933, while an additional one million people fled from the Republic, causing a labour shortage in that area, which Stalin sought to compensate by deporting other ethnicities there. The
Great Purge affected many Kazakh families, sometimes even decimating entire lineages. During the industrialization drives ordered by
Joseph Stalin and the shift of key industries from the
Eastern Front (World War II), Kazakhstan developed many oil wells, mines, steel plants and mineral refineries. However, the focus on heavy industry stunted the development of light industries that could manufacture consumer goods. In 1949, the
Turkestan–Siberia Railway was constructed in the Kazakh SSR which linked the country to Russia via rail. Thousands of kilometers of road were constructed throughout the country, linking the previously disconnected parts of the country and facilitating development. Many Kazakhs served with distinction in the
Great Patriotic War, with
Bauyrzhan Momyshuly,
Manshuk Mametova and
Sadyk Abdujabbarov becoming household names. (see
List of Kazakh Heroes of the Soviet Union) During the 1950s and 1960s, Soviet citizens were urged to settle in the
Virgin Lands of the Kazakh Soviet Socialist Republic. This was initiated by
Nikita Khrushchev to utilize potential land for cultivation and to boost agricultural production. During the 22-year tenure of
Dinmukhamed Kunaev, the Kazakh SSR saw further advancements in economic prosperity, energy production and industrialization. The immigration policies of the USSR led to a drastic influx of
Russians, eventually skewing the ethnic composition of the republic. With non-Kazakhs becoming the majority, the use of the Kazakh language declined and would only see a revival after the dissolution of the USSR. The
Russian language would become the
Lingua franca and dominant language. Other immigrant nationalities in the SSR included
Ukrainians,
Germans,
Kyrgyz, Belarusians,
Koreans,
Tatars, and
Uyghurs. Kazakhs mixed well with the immigrants and helped create an inclusive multi-ethnic state. On 25 March 1990, Kazakhstan held its first elections with
Nursultan Nazarbayev, the chairman of the Supreme Soviet
elected as its first president. Later that year on 25 October, it then declared sovereignty. The republic participated in a
referendum to preserve the
union in a different entity with 94.1% voting in favour. It did not happen when hardline communists in
Moscow took
control of the government in August. Nazarbayev then condemned the failed coup and prepared to declare independence. As a result of those events, the Kazakh SSR was renamed to the
Republic of Kazakhstan on 10 December 1991. It declared independence on 16 December (the fifth anniversary of
Jeltoqsan), becoming the last Soviet constituency to secede. Its capital was the site of the
Alma-Ata Protocol on 21 December 1991 that dissolved the Soviet Union and formed the
Commonwealth of Independent States in its place, which Kazakhstan promptly joined. The Soviet Union officially ceased to exist as a sovereign state on 26 December 1991 and Kazakhstan became an internationally recognized independent state. On 28 January 1993, the new
Constitution of Kazakhstan was officially adopted. ==Population dynamics==
