The first decision to hold Victory Day parades was taken by Soviet dictator Joseph Stalin himself after the country lost an estimated 27 million people defending its territory and the Eastern Front.
The tradition has been given extra fanfare by President Vladimir Putin, an ardent nationalist whose patriotic fervour has helped him win strong backing from the middle class.
The Victory Day parades have expanded during Putin's 13 years in power to include heavy intercontinental missiles and Tu-95 bombers that can easily reach the shores of the United States.
"We will always remember that it was specifically Russia, the Soviet Union, that undermined the abhorrent, bloody, supercilious plans of the Nazis and kept them from controlling the world," Putin said at the nationally televised ceremony.
