May Day, day commemorating the historic struggles and gains made by workers and the labour movement, observed in many countries on May 1. In the United States and Canada a similar observance, known as Labor Day, occurs on the first Monday of September.

In Europe May 1 was historically associated with rural pagan festivals (see May Day), but the original meaning of the day was gradually replaced by the modern association with the labour movement. In the Soviet Union, leaders embraced the new holiday, believing it would encourage workers in Europe and the United States to unite against capitalism. The day became a significant holiday in the Soviet Union and in the Eastern-bloc countries, with high-profile parades, including one in Moscow’s Red Square presided over by top government and Communist Party functionaries, celebrating the worker and showcasing Soviet military might. In Germany Labour Day became an official holiday in 1933 after the rise of the Nazi Party. Ironically, Germany abolished free unions the day after establishing the holiday, virtually destroying the German labour movement.
