Polish–Lithuanian occupation of Moscow significant person Stanisław Żółkiewski
The Polish-Lithuanian Commonwealth occupation of Moscow took place between 1610 and 1612 during the Polish–Russian War, when the Kremlin was occupied by a Polish-Lithuanian garrison under the command of Stanisław Żółkiewski and assisted by Russian boyars led by Mikhail Saltykov. The occupation coincided with Russia's Time of Troubles.
From March 1611 to the autumn of 1612, the Cossacks of Prince Dmitry Trubetskoy besieged Moscow and the Polish-Lithuanian forces there. The city was finally liberated by the Second People's Militia, and the date of the capture of Kitay-Gorod is celebrated in modern Russia as the Day of National Unity on November 4, alongside festivities in honour of Our Lady of Kazan.
