The United States Marine Corps was established on this day in 1775 during the Revolutionary War. Captain Samuel Nichols established the Continental Marines, the root of the modern Marine Corps, to serve as the muscle of the Continental Navy. It did not become the United States Marine Corps until 1798 when Congress created in preparation for conflict with post-revolutionary France.
Since their charged debut the Marine Corps have served in every American foreign armed conflict. Opening History has posters and photos relevant to the Marine Corps in World Wars I and II, along with other military history resources. The two images are from University of Minnesota Libraries and the Unitah County Library.
