22 March] 1873 – 20 April or 18 May 1919), often referred to mononymously as Amankeldı or Amangeldy, was a Kazakh revolutionary who was leader of the Central Asian revolt of 1916 in Kazakhstan.

Amankeldı Üderbaiūly İmanov was born on 3 April 1873 into a family of poor Qypşaq [ru][1] nomads in the Turgaysky Uyezd of the Turgay Oblast (now the Amangeldi District in Kostanay Region).

[3] It has been claimed by the Great Soviet Encyclopedia that İmanov supported imprisoned Kazakhs in the Russian capital of Saint Petersburg, but evidence has yet to emerge to prove this.

[4] He was first arrested by Tsarist authorities in 1896 for inciting Kazakh peasants to armed rebellion against beys, and either remained in prison until 1911[5] or was imprisoned several times between 1896 and 1908, having participated in the Russian Revolution of 1905.

[2] On 25 June 1916, Tsar Nicholas II issued an edict, termed "the requisition" (Russian: реквизиция, romanized: rekvizitsiya).

The Russian government delayed the requisition to 15 September 1916 amidst popular outcry, but it failed to stem the resentment, and an uprising under İmanov's leadership soon began.

[3] In the early days of the uprising, İmanov connected with several fellow revolutionaries in Turgay Oblast; alongside Alibi Dzhangildin, he showcased films to Kazakhs as incentive to join the revolt.

Originally, the testimony written in Älıby Jangeldin's diaries, that İmanov was killed by the authorities of the Alash Autonomy, was accepted as objective fact by Soviet historians.

This evolution was supported by the Soviet government, which painted İmanov as a member of the peasantry responsible for leading an anti-colonial uprising.
