Industrial Revolution

Tammany Hall was the Democratic headquarters in New York City and it was also Boss Tweed's office.

Tammany Hall (Founded May 12, 1789 as the Tammany Society, and also known as the Society of St. Tammany, the Sons of St. Tammany, or the Columbian Order), was the Democratic Party political machine that played a major role in controlling New York City politics and helping immigrants (most notably the Irish) rise up in American politics from the 1790s to the 1960s. It usually controlled Democratic Party nominations and patronage in Manhattan from the mayoral victory of Fernando Wood in 1854 through the election of John P. O'Brien in 1932. Tammany Hall was permanently weakened by the election of Fiorello La Guardia on a "fusion" ticket of Republicans, reform-minded Democrats, and independents in 1934, and despite a brief resurgence in the 1950s, it ceased to exist in the 1960s.
