Russian Turkestan
In the 13th century Kazakhstan was under the dominion of the Mongol Empire, and remained in the sphere of Mongol successor states for 300 years. Portions of the country began to be annexed by the Russian Empire in the 16th century, the remainder gradually absorbed into Russian Turkestan beginning in 1867. The modern Republic of Kazakhstan became a political entity during the 1930s Soviet subdivision of Russian Turkestan.
