Polish–Lithuanian–Muscovite Commonwealth
After this, Russia entered the Time of Troubles. Because of this, the Polish-Muscovite War began between the Commonwealth and the Tsardom. While this war secured Russian independence, it also had Russia give up some territories to Poland-Lithuania. Because of the war, many weird things also happened to the Russian throne, including Władysław IV Vasa, a Polish prince, (unofficially) becoming Tsar of Russia.
