The history of the United States Marine Corps (USMC) begins with the founding of the Continental Marines on 10 November 1775 to conduct ship-to-ship fighting, provide shipboard security and discipline enforcement, and assist in landing forces.
Marine Corps birthday Nov. 10 is the official birthday of the U.S. Marine Corps. The Marine Corps traces its roots back to the Second Continental Congress in 1775, which established a resolution stating that two Battalions of Marines be raised as forces to land with the fleet.
