The Continental Marines (Active November 10, 1775 - June 1785) was the primary naval infantry force of the American Colonies during the American Revolutionary War of 1775 - 1783 to fight against the British Empire.
The main purposes of these Marines were to act as guards for the Commanding officers, engage in close quarters ship-to-ship combat, and lead amphibious shore parties.
The Continental Marines were established on November 10, 1775, in the Tun Tavern in Philadelphia, Pennsylvania, when the Continental Congress ordered the creation of the two Battalions of Marines.
Their first and only Commandant was Captain Samuel Nicholas and their first barracks was located in Philadelphia, PA.
It was during World War I of the 20th Century that the nickname "Leathernecks" was adopted into widespread use, which referred to the collars of the uniforms that the American Marines wore during the Revolutionary period.
