The Seven Boyars were a group of Russian nobles who deposed Tsar Vasily Shuisky on 17 July 1610 and later that year, after Russia lost the Battle of Klushino, acquiesced to the Polish entry into Moscow. The seven were Princes Fedor Mstislavsky (the leader of the group), Ivan Mikhailovich Vorotynskii, Andrei Vasilevich Trubetskoi, Andrei Vasilevich Golitsyn, Boris Mikhailovich Lykov-Obolenskii, and Boyars Ivan Nikitich Romanov and Fedor Ivanovich Sheremetev. Due to the Polish advance into Russia, the Bolotnikov rebellion of 1606 to 1607, and other unrest during the Time of Troubles of 1598 to 1613, Shuisky ((r. 1606 – 1610)) was never very popular, nor was he able to effectively rule outside of the capital itself. The seven deposed him and he was forcibly tonsured as a monk in the Chudov Monastery in the Kremlin. (Stanisław Żółkiewski later carried Shuisky off to Poland, where he died in prison at Gostynin near Warsaw in 1612.) On 27 August 1610, the seven agreed to accept Władysław, the eldest son of the King of Poland, as Tsar of Russia. The Poles entered the city on 21 September. While some consider the rule of the Seven in Moscow to have lasted only from about June 1610 until the arrival of the Poles in September, others regard their rule to have lasted until the Poles were driven from Moscow by the popular movement headed by Kuzma Minin, Prince Dmitry Pozharsky, and Prince Dmitry Troubetskoy in 1612. Their power to act after September 1610, however, was rather nominal.
