After the death of Fedor III (r. 1676–82), there was confusion as to who would succeed to the throne, since the Miloslavskii and Naryshkin clans competed for power. At first, the healthy ten-year-old Peter (r. 1682–1725) was acclaimed tsar with his mother, Natalia Naryshkina, acting as regent. A month later, Sofiia, in the name of her sickly sixteen-year-old brother Ivan, claimed the crown. Sofiia spread rumors that the Naryshkins planned to kill Ivan, and the strel’tsy revolted to prevent the outrage. They butchered several Naryshkins and their allies, and terrorized Peter and his mother. A unique compromise was reached: Ivan V and Peter I would reign as co-tsars, with Sofiia ruling as regent.
