Catherine reformed the administration of Russian guberniyas (governorates), and many new cities and towns were founded on her orders. An admirer of Peter the Great, Catherine continued to modernise Russia along Western European lines. However, military conscription and the economy continued to depend on serfdom, and the increasing demands of the state and of private landowners intensified the exploitation of serf labour. This was one of the chief reasons behind rebellions, including the large-scale Pugachev Rebellion of Cossacks, nomads, peoples of Volga and peasants.
