False Dmitriy I
The Time of Troubles included a civil war in which a struggle over the throne was complicated by the machinations of rival boyar factions, the intervention of regional powers Poland and Sweden, and intense popular discontent, led by Ivan Bolotnikov. False Dmitriy I and his Polish garrison were overthrown, and a boyar, Vasily Shuysky, was proclaimed tsar in 1606. In his attempt to retain the throne, Shuysky allied himself with the Swedes, unleashing the Ingrian War with Sweden. False Dmitry II, allied with the Poles, appeared under the walls of Moscow and set up a mock court in the village of Tushino.
