Sigismund's invasion of Russia (1609–1618)

Sigismund's major goals were achieving stability of government, combating Protestantism, and expanding Poland's territory. While the Russians were embroiled in a civil war known as the Time of Troubles, Sigismund saw an opportunity to invade Russia and take power. Sweden also became involved, but never made a firm alliance with any one side.
