Pugachev's Rebellion
Pugachev's Rebellion (Peasants' War 1773-75, Cossack Rebellion) of 1773-75 was the principal revolt in a series of popular rebellions that took place in the Russian Empire after Catherine II seized power in 1762. It began as an organized insurrection of Yaik Cossacks headed by Yemelyan Pugachev, a disaffected ex-lieutenant of the Imperial Russian Army, against a background of profound peasant unrest and war with the Ottoman Empire. After initial success, Pugachev assumed leadership of an alternative government in the name of the assassinated Tsar Peter III and proclaimed an end to serfdom. This organized leadership presented a challenge to the imperial administration of Catherine II.
Pugachev's Rebellion
By late 1774 the tide was turning, and the Russian army's victory at Tsaritsyn left 9,000-10,000 rebels dead. Russian General Panin's savage reprisals, after the capture of Penza, completed their discomfiture. By early September, the rebellion was crushed. Yemelyan Pugachev was betrayed by his own Cossacks when he tried to flee in mid-September 1774. He was beheaded and dismembered on 21 January 1775, in Moscow.
