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.
Wozdwizhenskaya Fortress
The Wozdwizhenskaya Cossacks supported the Imperial government during the Pugachev's Rebellion in 1773—1775. The Fortress was completely destroyed by the bombardment of the Red Guards units in May 1918 for supporting the counterrevolution of Alexander Dutov against the Soviet authorities.
