The Mangyshlak peninsula was overtaken in 1639 by
Kalmyks. Following the
Russian conquest of Turkestan, several administrative reforms were instituted on the peninsula by the Russian authorities. These included the confiscation of pastureland, the construction of military settlements, the construction of a residence for the
Junior jüz's leader, an increase in the
kibitka tax to ₽3.50, the inclusion of the territory into the
Uralsk Oblast, and restrictions on the freedom of the nomadic tribes of the Junior jüz to migrate. In 1870, in response to the aforementioned reforms, the
Adai rebellion took place on the Mangyshlak peninsula. The Russian Empire called upon
Cossack reinforcements from
Dagestan to quell the rebellion, defeating it and brutally suppressing the Adai tribes. As punishment for the rebellion, the kibitka tax on the Adai was increased for a period of two years and 90,000 sheep were confiscated from them. The rebellion's leaders, including , , , Erjan Qululy, and Ermaghambet Qululy, were all arrested and later died in Russian prisons. Upon the Soviet takeover of
Russian Turkestan, the territory of the
Transcaspian Oblast, which contained the Mangyshlak Peninsula, was initially assigned to the
Turkestan ASSR. In August 1920, at the request of Kazakh activists, Mangyshlak was transferred to the
Kazakh ASSR. == Cartography ==
