Ivan V of Russia supreme ruler and Tsar of all of Russia. The struggle for power within the family had finally ended, and Peter was left to bring Russia into a new age of westernization. In 1730, more than 30 years after Ivan's death, his second surviving daughter Anna, Duchess of Courland was invited to the throne of Russia by the country's privy council. She ruled for more than 10 years, and was succeeded by Ivan's infant great-grandson Ivan VI, but a palace coup engineered in 1741, by Ivan's niece Elizabeth, resulted in the throne passing finally to the progeny of Peter the Great.
