A corrupt American politician who exemplified the idea of the "political machine"
William M. "Boss" Tweed was the boss of Tammany Hall, the Democratic Party headquarters in New York City. Tweed ran an organisation that helped immigrants in neighbourhoods, most notably the Irish, and rose in politics as his society expanded. He was lated convicted in 1877 for stealing an estimated 1-2$million in taxes through political corruption.
Tweed's system of local boss control of neighborhoods attracted working-class Irish in New York. With this support he could 'climb higher' and at the same time. His political machine played a major role in controlling New York City politics.
