Unity Day, Day of People's Unity (or National Unity Day; Russian: День народного единства) was celebrated in Russian Empire until 1917 and in Russia from 2005. Held on November 4 (October 26, Old Style), it commemorates the popular uprising which expelled the Polish-Lithuanian occupation force from Moscow in November 1612, and more generally the end of the Time of Troubles and foreign intervention in Russia in the Polish-Muscovite War (1605—1618).
