Definition
The Tammany Society, also known as Tammany Hall, was a New York City political organization with significant influence from the late 18th century through the mid-20th century. Initially a fraternal society, it evolved into a dominant political machine. It used patronage, and sometimes corruption, to maintain control. Think of it as a historical example of power dynamics, like a simplified version of the politics in "House of Cards," but on a local level.
