Sophia Alekseyevna (September 17 (27), 1657 - July 3 (14), 1704) was a regent of Russia (1682-1689) who allied herself with a singularly capable courtier and politician, Prince Vasily Galitzine, to install herself as a regent during the minority of her brothers, Peter I and Ivan V. The activity of this "bogatyr-tsarevna" (as Sergey Solovyov called her) was all the more extraordinary, as Muscovite women usually kept themselves aloof from politics. Wikipedia
