Two of the most significant military parades on Red Square were 1941 October Revolution Parade, when the city was besieged by Germans and troops were leaving Red Square straight to the front lines, and the Victory Parade in 1945, when the banners of defeated Nazi armies were thrown at the foot of Lenin's Mausoleum. The Soviet Union held many parades in Red Square for May Day (until 1969), Victory Day, and October Revolution Day, which consisted of propaganda, flags, labor demonstration, marching troops, and showing off of tanks and missiles. Individual parades have been held on Defender of the Fatherland Day (23 February 1925), the Day of Tankmen (8 September 1946), and the state funeral of Joseph Stalin (9 March 1953). On Victory Day in 1945, 1965, 1985, and 1990, there were Soviet military marches and parades as well, and since 1995, the annual Moscow Victory Day Parade has been held on the square, marking anniversary of the defeat of Nazi Germany in World War II.
