The Immortal Regiment is a massive civil event in major cities in Russia and around the world every 9 May during the Victory Day celebrations. It is also a public non-profit organization, created in Russia on a voluntary basis with the aim of "immortalizing" the memory of home front workers, armed forces service personnel, partisans, personnel of resistance organizations, and personnel of law enforcement and emergency services. It involves people carrying on the memory of war veterans, with participants carrying pictures of relatives and/or family friends who served in the country's labor sector, paramilitary units, the Soviet Armed Forces and law enforcement organizations during the Second World War.

Victory Day is a holiday that commemorates the Soviet Union victory over Nazi Germany in 1945. It was first inaugurated in the 15 republics of the Soviet Union following the signing of the German Instrument of Surrender late in the evening on 8 May 1945. The Soviet government announced the victory early on 9 May after the signing ceremony in Berlin. Although the official inauguration occurred in 1945, the holiday became a non-labor day only in 1965.
