About The Gadsden Flag: The Gadsden flag is a historical American flag with a yellow field depicting a rattlesnake coiled and ready to strike. Positioned below the rattlesnake are the words "Dont tread on me". The flag is named after American general and statesman Christopher Gadsden, who designed it in 1775 during the American revolution. Since the Revolution, the flag has seen times of reintroduction as a symbol of American patriotism, a symbol of disagreement with government, or a symbol of support for civil liberties.
