Tammanend or Tammanund, a pre-Revolutionary Indian chief of the Delaware tribe, was supposed to have signed the document of friendly relations with William Penn. Not much is known about him except that his name meant «affable». Patriots of the Revolution borrowed his name when they organized Tammany societies, all of which died out except Tammany Hall.
This society was designated a social club for New Yorkers, but it became politically oriented and attracted prominent politicians, including Aaron Burr. During the presidency of Andrew Jackson, the organization dominated New York politics, and it continued that domination until the first half of the twentieth century.
Tammany Hall was investigated many times on charges of political corruption, including bribery. It received a great deal of unfavorable publicity from the press, especially in the 1870s when led by W. M. Tweed, known as Boss Tweed, who fleeced the city of New York of over $100 million. The continued widespread corruption and specific nefarious incidents led to the figurative use of the name Tammany Hall for wholesale political or municipal malpractice.
