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).
Pugachev's Rebellion
In 1773 Pugachev's army attacked Samara and occupied it. His greatest victory came with the taking of Kazan, by which time his captured territory stretched from the Volga to the Ural mountains. Though fairly well-organized for a revolt at the time, Pugachev's main advantage early on was the lack of seriousness about Pugachev's rebellion. Catherine the Great regarded the troublesome Cossack as a joke and put a small bounty of about 500 rubles on his head. But by 1774, the threat was more seriously addressed; by November the bounty was over 28,000 rubles. The Russian general Michelson lost many men due to a lack of transportation and discipline among his troops, while Pugachev scored several important victories.
