The Military Order of the World Wars (MOWW) is an American social organization of military officers of the United States and their descendants. It was created in 1919 as the Military Order of the World War at the suggestion of General of the Armies John J. Pershing as a fraternity for American military officers coming out of World War I. Two decades later, when the United States became involved in World War II, the conflict reference was pluralized to its current title of Military Order of the World Wars. Though the society's title has not been changed since 1945, it accepts additional members from other conflicts and non-conflict service, including those in current military service, retired military service, and former military service. It also accepts members who are lineal descendants from a qualifying officer and family members within two degrees of consanguinity as hereditary members.
