Catherine took power after a conspiracy deposed her husband, Peter III (1728–1762), and her reign saw the high point in the influence of the Russian nobility. Peter III, under pressure from the nobility, had already increased the authority of the great landed proprietors over their muzhiks and serfs. In spite of the duties imposed on the nobles by the first prominent "modernizer" of Russia, Tsar Peter I (1672–1725), and despite Catherine's friendships with the western European thinkers of the Enlightenment (in particular Denis Diderot, Voltaire and Montesquieu) Catherine found it impractical to improve the lot of her poorest subjects, who continued to suffer (for example) military conscription. The distinctions between peasant rights on votchina and pomestie estates virtually disappeared in law as well as in practice during her reign.

In 1775 Catherine decreed a Statute for the Administration of the Provinces of the Russian Empire. The Statute sought to efficiently govern Russia by increasing population and dividing the country into provinces and districts. By the end of her reign, there were fifty provinces, nearly 500 districts, more than double the government officials, and they were spending six times as much as previously on local government. In 1785 Catherine conferred on the nobility the Charter to the Nobility, increasing further the power of the landed oligarchs. Nobles in each district elected a Marshal of the Nobility who spoke on their behalf to the monarch on issues of concern to them—mainly economic ones. In the same year, Catherine issued the Charter of the Towns which distributed all people into six groups in order to control the power of nobles and create a middle estate. Each of these charters had major flaws and Catherine seemingly could not gain the reform she had long desired for her country, after her death this was made even more obvious through her son Paul.
