Supreme Privy Council
After Peter's death, his wife Catherine I ascended the throne. But when she died in 1727, Peter's grandson, Peter II, was crowned tsar. In 1730, Anna Ivanovna, whose father Ivan V had been co-ruler with Peter, ascended the throne. The Supreme Privy Council, a government body established by Catherine I that put Anna on the throne, attempted to impose various conditions on her. In her struggle against those restrictions, Anna had the support of other nobles who feared oligarchic rule more than autocracy. Thus the principle of autocracy continued to receive strong support despite chaotic struggles for the throne.
