On Nov. 11, 1921, a casket bearing an unknown soldier from World War I was placed on a horse-drawn caisson from the Capitol and taken on a procession through Washington, D.C., across the Potomac River into Virginia and to a state funeral held at the Tomb of the Unknown Soldier in Arlington National Cemetery.
During the 100 years since, one unknown service member each from World War II, the Korean War and Vietnam War were laid to rest there, representing service, valor, sacrifice and mourning.
On this centennial anniversary of the tomb’s creation, here’s a look through historical photos at the meaning behind the memorial dedicated to service members who gave their lives for their country.
