False Dmitry II
False Dmitry I quickly became unpopular, since many in Russia saw him as a tool of the Poles. On 17 May 1606, ten days after his marriage, Dmitry was killed by armed mobs during an uprising in Moscow after he was ousted from the Kremlin. Many of his Polish advisors were also killed or imprisoned during the rebellion. Vasili IV Shuysky, a member of the house of Shuysky and a relative of the Rurikids, seized power and was elected tsar by an assembly of his supporters. Shuysky was a weak ruler, not satisfying the Russian boyars, Commonwealth magnates, Cossacks, or the German mercenaries who held power in Russia's conflicts. A new impostor, False Dmitry II, soon came forward as the heir. Like his predecessor, False Dmitry II enjoyed the support of King Sigismund and the Polish–Lithuanian magnates.
