On what date did the Continental Congress establish the United States Marine Corps as a regular branch of service?

The United States Marine Corps was established as a regular branch of service by the Continental Congress on November 10, 1775. This date is significant as it marks the formal recognition of the Marines as a distinct and organized military force, specifically designed to serve as an elite fighting unit that would conduct ship-to-ship fighting, provide shipboard security, and assist in land operations.

The establishment of the Marine Corps was crucial during the American Revolutionary War, as the newly formed unit played a vital role in various military campaigns. November 10 is now celebrated annually as the Marine Corps Birthday, commemorating the long and storied history of this branch of the military.
