The first military parade took place on 7 November 1919 on the first anniversary of the revolution. The parade in 1941 is particularly revered as it took place during the Battle of Moscow, during which many of the soldiers on the parade would be killed in action. In 1953, the parade took place as the first one to not be inspected by officers on horseback. The practice of foreign leaders began in 1957 with Mao Zedong attending that year's parade as part of a state visit, continuing throughout the next two decades with Ethiopian leader Mengistu Haile Mariam's attendance in 1980 and the leaders of Warsaw Pact and USSR-allied nations in 1967, 1977 and 1987. The 1989 parade was the first to have a drill routine by the massed bands take place. During the final parade in 1990, an assassination attempt was made on the life of President Mikhail Gorbachev, attempt to kill President by Alexander Shmonov, a locksmith from Leningrad. The two bullets he fired missed as he was tackled to the ground by crowds of demonstrators. The only time that a Soviet leader never attended a parade was in 1983 when Yuri Andropov did not attend the parade due to a sickness and his associate Konstantin Chernenko stood in for him.
