Name the commander who defeated the Polish invaders during the time of troubles.

It was Dmitry Pozharsky. In 1612, the situation in the country continued to be dire. The capital was still in the hands of the enemy, and the first militia could not succeed and failed. Thus, the second militia was assembled in Nizhny Novgorod. This time it was organized by Pozharsky and Minin. Their forces approached the city and by the end of 1612 they were able to drive the invaders out of Moscow. The turmoil ended, but the country was in complete ruin. Moreover, there was no king who was at the head of the country.
