In 1611, Kuzma Minin and Dmitry Pozharsky formed a new army to launch an uprising against the Polish occupiers. The Poles eventually withdrew from Moscow in September 1612 after pillaging and burning the city. When news reached Sigismund he hurried with a relief force, but was unable to commence an attack. The war continued with little military action until 1618 when the Truce of Deulino was signed, which granted Poland new territories, including the city of Smolensk. The agreement marked the greatest geographical expansion of the Polish–Lithuanian Commonwealth until the loss of Livonia in 1629. However, Russia was able to retain independence and Michael Romanov was crowned Tsar in 1613. This established the Romanov dynasty which ruled Russia until the February Revolution in 1917. Sigismund's personal ambition of ruling the vast lands in the east as well as converting its populace to Catholicism ended in a fiasco. According to Alexander Gillespie, approximately five million Russians died between 1598 and 1613, the result of continuous conflict, civil war, instigated famine and Sigismund's politics.
