History of the Marine Corps Birthday
The Marine Corps Was Established in 1775
On November 10, 1775, the Second Continental Congress authorized the formation of two battalions of Marines to serve during the Revolutionary War. This act laid the foundation for what would eventually become the modern United States Marine Corps.
The Birthplace of the Continental Marines
Tun Tavern in Philadelphia is widely associated with the early recruitment of Continental Marines. Historical accounts vary in detail, but the location is closely tied to Marine Corps lore as the symbolic birthplace of the Corps. The first Marines were recruited during the Revolutionary War for service alongside the Continental Navy.
From Continental Marines to U.S. Marine Corps
The Continental Marines of the Revolutionary War era eventually evolved into the modern United States Marine Corps, a transformation shaped by decades of organizational change, new missions and an expanding role within the U.S. military.
Why Is the Marine Corps Birthday November 10?
November 10, 1775, marks the date the Continental Congress authorized the formation of the Continental Marines. That date became the Marine Corps’ recognized founding day, and Marines have continued to commemorate it annually ever since.
It’s important to note that while the Marine Corps traces its roots to 1775, the modern institution underwent later organizational changes rather than operating as one continuous, unbroken entity from that founding moment.
