Supreme Privy Council
Peter the Great had two wives, Yevdokiya Lopukhina (the daughter of a minor noble) and Marfa Skavronskaya (a Lithuanian peasant, renamed Catherine after her conversion to Orthodoxy). Catherine I's rise through Peter I's Table of Ranks, from a simple peasant to empress, embodied the Petrine spirit, making it seem as though Peter I literally “created” her. With the help of Aleksandr Menshikov (her advisor, ex-lover and leader of the palace guards), she gained the throne by emphasizing this connection to Peter I and her maternal nature. Due to her poor health, Menshikov did much of the ruling. With Catherine I's blessing, he created the Supreme Privy Council, which consisted of six or so members. It ultimately took over most of the functions of the Ruling Senate (an advisory body founded by Peter I to oversee judicial, financial and administrative affairs) Almost immediately, Catherine I appointed Peter II, the grandson of Peter the Great, as her successor and she died after only two years of ruling.
