During the industrialization of the Soviet Union in the 1930s, the central regions of the Kazakh SSR developed large coal and metallurgic industries, as well as large collective farms.[8] On December 28, 1940, the Supreme Soviet of the Kazakh SSR passed a decree creating the Osakarov District. At the time of the decree, the newly formed district comprised nearly 40 collective farms and a handful of villages. These farms largely grew various cereals, but were also home to cattle, sheep, horses, pigs, and poultry farming. Upon the outbreak of World War II, over 6,000 people in the district went to fight on the Eastern Front, 7 female Komsomol brigades took up work in their absence, and the district's furniture and record factory were converted into producing various equipment parts and linens for the front line effort. As part of the Virgin Lands campaign, a number of new farms were formed in the district during the 1950s and 1960s.
In 1993, 2002, and 2004, a number of villages in the district were had their names changed from Russian-derived names to Kazakh-derived names.
