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.
Military history of the Russian Empire
During the 1768–1774 war with the Ottoman Empire, Russia experienced a major social upheaval, the Pugachev Uprising. In 1773 a Don Cossack, Emel'yan Pugachev, declared himself as the re-emergent tsar Peter III. Other Cossacks, various Turkic tribes that felt the impingement of the Russian centralizing state, and industrial workers in the Ural Mountains, as well as peasants hoping to escape serfdom, all joined in the rebellion. Russia's preoccupation with the war enabled Pugachev to take control of a part of the Volga area, but the regular army crushed the rebellion in 1774.
