21. What precedent motivated US officials to propose a tomb for an American Unknown?
From Quiz Tombs of Unknown Soldiers
Answer:
Similar Tombs had already been started by England and France
As early as 1916, discussions in Great Britain and France sought ways to memorialize the staggering numbers of their unknown dead. The Tomb concept took hold, and planning began in both countries shortly after the Armistice. The US took notice, and began its own review. Army Chief of Staff General Peyton March was somewhat cool about the idea, explaining that Army Graves Registration might eventually identify all US unknowns, thus rendering the Tomb useless. But the project was completed, and the American Unknown was interred on 11 November 1921, the third anniversary of the Armistice.
The concept of national tombs spread through following years; at least 40 Tombs/Memorials to Unknown Soldiers were built around the world in countries as far-flung as Egypt, Venezuela, Namibia, and Ukraine. Brazil's Monument and Tomb of the Unknown Soldier of World War II is in faraway Pistoia, Tuscany, Italy. Lesser known Tombs in the US include the Tomb of the Unknown Revolutionary War Soldier in Philadelphia Pennsylvania, and the Tomb of the Unknown Confederate Soldier in Biloxi Mississippi.
