Which U.S. military branch celebrated its 250th anniversary in 2025 after being founded on November 10, 1775?
Answer
United States Marine Corps
The United States Marine Corps celebrated its 250th anniversary in 2025 after being founded on November 10, 1775.
The Continental Congress authorized the formation of two battalions of Marines on November 10, 1775, during the American Revolutionary War. That date is commemorated annually as the Marine Corps birthday.
The 250th anniversary of the Marine Corps therefore fell in 2025, one year before America250’s national observance in 2026. The two anniversaries are related but mark different events: the Corps’ creation and the Declaration of Independence.
The Marine Corps is sometimes confused with the Continental Army, established earlier in 1775, or the modern Navy, whose institutional history has a different founding timeline.
