Лжедмитрий II
The combined Russo-Swedish forces set out from Novgorod late in 1609 and marched towards Moscow, relieving the Siege of Troitse-Sergiyeva Lavra on their way. They dispersed the supporters of False Dmitry II, who maintained an alternative court in Tushino near Moscow and challenged the authority of Vasily IV. In the aftermath, some of the Tushino boyars summoned Wladyslaw IV to lay his claim to the Russian throne, while Skopin-Shuisky was poisoned at the behest of his uncle and rival, Prince Dmitry Shuisky.
