The American Legion will celebrate its 99th birthday on March 15. It is the day in 1919 when the first American Legion caucus, held by members of the American Expeditionary Force, convened in Paris.

A birthday speech is available here for posts to use during events that commemorate this anniversary. Remember to use the hashtag #LegionFamilyDinner when promoting your event.

American Legion posts across the country hold events – public, private or both – to commemorate this anniversary. For example, in 1939 for the Legion's 20th birthday, Battle Mountain Post 71 in Hot Springs, S.D., celebrated with a 40-pound birthday cake – 2 pounds for every year of The American Legion's history. Posts can upload recaps and photos of their birthday celebrations (and other community activities) online at

Members of The American Legion Amateur Radio Club will operate a special event station on March 10, at 1 p.m. EST to commemorate the Legion's birthday.
