The changing of the guard is an incredibly beautiful and spectacular ceremony that has been fixed in the Russian military charters and articles since the reign of Peter the Great, although similar ceremonies were conducted during the reign of Grand Duke Ivan the III. The recreation of the details of the ceremony required a huge amount of work on the part of military historians. The first parade changing of the guard in the Moscow Kremlin in the modern era, after a break of almost 80 years, took place on April the 16th, 2005.
