The American Legion commissioned the cross to commemorate the 49 servicemen that died overseas in World War I. The monument was designed by Washington, D.C. architect and artist John Joseph Earley, and was erected between 1919 and 1925. The Latin cross design was selected as it mirrored the cross structures used on the gravesites of soldiers buried after the war in Europe and other locations. United States Secretary of the Navy Josephus Daniels spoke at the monument's groundbreaking ceremony in September 1919, with a formal dedication ceremony in July 1925. The name "Peace Cross" was first used in the Washington, D.C., area in 1898 for a twenty-foot-tall cross erected on the grounds of Washington National Cathedral to mark the end of the Spanish–American War.
The cross was originally built on private lands, but the lands were turned over to the state's Maryland-National Capital Park and Planning Commission in 1961. The Commission has since overseen the maintenance of the memorial. The land has been heavily developed over the years, with a divided highway passing by it and the memorial on its median. The Commission installed nighttime illumination to avoid this becoming a safety hazard. Additionally, more war memorial structures have been erected in the same general area, creating the Veterans Memorial Park.
