Peter III created two measures in 1762 that influenced the abolition of serfdom. He ended mandatory military service for nobles with the abolition of compulsory noble state service. This provided a rationale to end serfdom. Second, was the secularization of the church estates, which transferred its peasants and land to state jurisdiction. In 1775 measures were taken by Catherine II to prosecute estate owners for the cruel treatment of serfs. These measures were strengthened in 1817 and the late 1820s. There were even laws that required estate owners to help serfs in time of famine, which included grain to be kept in reserve. These policies failed to aid famines in the early nineteenth century due to estate owner negligence.
