On what date was the United States Marine Corps founded at Tun Tavern?

The United States Marine Corps was founded on November 10, 1775, at Tun Tavern in Philadelphia.

The Second Continental Congress authorized the creation of two battalions of Continental Marines during the Revolutionary War. The Marines served aboard Continental Navy ships and also took part in operations ashore, combining shipboard security, infantry fighting, and expeditionary duties.

Tun Tavern is traditionally remembered as the place where the first Marine recruits were gathered. The Corps later adopted November 10 as its birthday, and the date remains an important annual observance in the United States military.

The Marine Corps was founded before the United States formally declared independence. Its origins therefore belong to the Revolutionary War’s opening period, when Congress was building national military institutions while the colonies were still politically connected to Great Britain.
