1921 Persian coup d'état

<p>1921 Persian coup d'état, known in <a href="/facts/Iran/24yukge8">Iran</a> as 3 Esfand 1299 coup d'état , refers to several major events in <a href="/facts/Qajar_Persia/qSYcpC8f">Qajar Persia</a> in 1921, which eventually led to the deposition of the <a href="/facts/Qajar_dynasty/sz5ulL0k">Qajar dynasty</a> and the establishment of the <a href="/facts/Pahlavi_Iran/WqU7j2W8">Pahlavi dynasty</a> as the ruling house of Iran in 1925.
</p><p>The events began with a <a href="/facts/Coup_d%27%C3%A9tat/eUK9HBw7">coup</a> by the <a href="/facts/Persian_Cossack_Brigade/Ma1dL4Xf">Persian Cossack Brigade</a> headed by <a href="/facts/Reza_Shah/3c5dNTrb">Reza Khan</a> on 22 February 1921. The precise level of <a href="/facts/United_Kingdom/kuPAILt2">British</a> involvement in the coup remains a matter of historical debate, but it is almost certain that <a href="/facts/Edmund_Ironside,_1st_Baron_Ironside/vdvcLlGo">Edmund Ironside</a> provided advice to the plotters. With this coup <a href="/facts/Zia_ol_Din_Tabatabaee/JX1BG95Q">Ziaoddin Tabatabaee</a> took over power and became prime minister. The coup was largely bloodless and faced little resistance. With his expanded forces and the Cossack Brigade, Reza Khan launched successful military actions to eliminate separatist and dissident movements in <a href="/facts/Tabriz/9aPM2trV">Tabriz</a>, <a href="/facts/Mashhad/2kYE0xWa">Mashhad</a> and the <a href="/facts/Jungle_Movement_of_Gilan/sRwFanvK">Jangalis</a> in <a href="/facts/Gilan_province/C0czQyXI">Gilan</a>. The <a href="/facts/Simko_Shikak_revolt_(1918%E2%80%931922)/55CH598J">campaign</a> against <a href="/facts/Simko_Shikak/SF6P8YmC">Simko</a> and the <a href="/facts/Kurds/kV90PCdW">Kurds</a> was less successful and lasted well into 1922, though eventually concluding with Iranian success.
