Which U.S. State Is the "Volunteer State"?

Tennessee is the Volunteer State.

Origin

During the War of 1812, Tennessee Governor Willie Blount called for 3,500 volunteers to join General Andrew Jackson's campaign against the Creek Red Sticks and later the British at New Orleans. Over 30,000 Tennesseans enlisted—far exceeding the quota—earning the nickname.

Reinforced in the Mexican–American War (1846–48) when 30,000+ volunteered for 2,800 slots. The spirit of volunteer service remains central to state identity.
