Tomb Of The Unknown Soldier Around The World

The United Kingdom and France conducted services connected with their 'monumental' graves (as presumably newly conceived, and in any case approved, by their respective armies) on Armistice Day 1920 (the burial itself taking place later in January of the following year in France). In Britain, the Tomb of the Unknown Warrior was created at Westminster Abbey, while in France La tombe du soldat inconnu was placed in the Arc de Triomphe. The idea of a symbolic Tomb of the Unknown Soldier then spread to other countries. In 1921, tombs were unveiled in the United States, Portugal and Italy. Since then, other nations have followed the practice and installed their own tombs. In the United States, further tombs have subsequently been created in order to represent different wars seen as key in its history.
In Chile and Ukraine, a second tomb was unveiled to commemorate The Unknown Sailor.
The tombs typically contain the remains of a dead soldier who is unidentified (or "known but to God" as the stone is sometimes inscribed) and thought to be impossible ever to identify, so that he might serve as a symbol for all of the unknown dead wherever they fell. The anonymity of the entombed soldier is key to the symbolism of the monument: since his identity is unknown, it could theoretically be the tomb of anyone who fell in service of the nation in question, and therefore serves as a monument to all of their sacrifices. Much work goes into trying to find a certain soldier, and to verify that it is indeed one of the relevant nation's soldiers.
