The Gadsden flag is a historical American flag with a yellow field depicting a timber rattlesnake coiled and ready to strike. Beneath the rattlesnake are the words "Dont Tread on Me" [sic]. Some modern versions of the flag include an apostrophe in the word "don't". Originating in the American Revolution, the flag has in modern days become a symbol of American right-libertarianism, and later the Tea Party movement.
