Marine Corps League
Mission The mission of the Marine Corps League is to promote the interest and to preserve traditions of the United States Marine Corps; strengthen the fraternity of Marines and their families; serve Marines, FMF Corpsmen, and FMF Chaplains who wear or who have worn the Eagle, Globe and Anchor; and foster the ideals of Americanism and patriotic volunteerism. History The Marine Corps League perpetuates the traditions and spirit of ALL Marines and Navy FMF Corpsmen, who proudly wear or who have worn the eagle, globe and anchor of the Corps. It takes great pride in crediting its founding in 1923 to World War I hero, then Major General Commandant John A. Lejeune. It takes equal pride in its Federal Charter, approved by An Act of the Seventy-Fifth Congress of the United States of America and signed and approved by President Franklin D. Roosevelt on August 4, 1937. The League is the only Federally Chartered Marine Corps related veterans organization in the country.
