Ivan VI Antonovich, also known as Ioann Antonovich, was Emperor of Russia from October 1740 until he was overthrown by his cousin Elizabeth Petrovna in December 1741. He was only two months old when he was proclaimed emperor and his mother, Anna Leopoldovna, named regent, but the throne was seized in a coup after little more than a year. Ivan and his parents were imprisoned far from the capital, and lived out their lives in captivity. Born: August 23, 1740 Died: July 15, 1764 In office: October 28, 1740 – December 6, 1741 Wiki link
