U.S. Marine Corps

United States Marine Corps

The Marine Corps was founded in 1775 in Philadelphia when the Second Continental Congress passed a resolution creating two battalions of Marines to serve with naval vessels. Its mission was to serve as an infantry unit aboard naval vessels with a responsibility to conduct both offensive and defensive combat during boarding actions and defending the ship's officers from mutiny.

America's first amphibious assault landing occurred early in the Revolutionary War when the Marines gained control of two British installations in the Bahamas.

Following the Revolutionary War and the formal re-establishment of the Marine Corps in 1798, Marines saw action in the quasi-war with France and in Santo Domingo. In 1805, the Marines took actions against the Barbary pirates along the "Shores of Tripoli" by capturing the city of Derna, the first time the U.S. flag ever flew over a foreign conquest.

The United States Marine Corps has served in nearly every conflict in United States history. By the early 20th century, the Marine Corps would become one of the dominant theorists and practitioners of amphibious warfare. Its ability to rapidly respond on short notice to expeditionary crises has made and continues to make it an important tool for U.S. foreign policy
