What is "bucktails"

n. (plural of bucktail English)

The Bucktails (1818–1826) were the faction of the Democratic-Republican Party in New York State opposed to the canal policy of Governor DeWitt Clinton. It was influenced by the Tammany Society. The name derives from a Tammany insignia, a deer's tail worn in the hat. The name was in use as early as 1791 when a bucktail worn on the headgear was adopted as the "official badge" of the Tammany Society. The wearing of the bucktail was said to have been suggested by its appearance in the costume of the Tammany Indians in the vicinity of New York.
