Yemelyan Pugachev
Yemelyan Ivanovich Pugachev () (c. 1742 – ) was a Russian Cossack who led a great popular insurrection during the reign of Catherine the Great, claiming to be her late husband, Emperor Peter III. Alexander Pushkin wrote a notable history of the rebellion, "The History of Pugachev", and he recounted some of the events in his novel "The Captain's Daughter" (1836).
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.
