There were numerous rebellions against this bondage, most often in conjunction with Cossack uprisings, such as the uprisings of Ivan Bolotnikov (1606–07), Stenka Razin (1667–71), Kondraty Bulavin (1707–09) and Yemelyan Pugachev (1773–75). While the Cossack uprisings benefited from disturbances among the peasants, and they in turn received an impetus from Cossack rebellion, none of the Cossack movements were directed against the institution of serfdom itself. Instead, peasants in Cossack-dominated areas became Cossacks during uprisings, thus escaping from the peasantry rather than directly organizing peasants against the institution. Rich Cossacks owned serfs themselves. Between the end of the Pugachev rebellion and the beginning of the 19th century, there were hundreds of outbreaks across Russia, and there was never a time when the peasantry was completely quiescent.
