William Poole - The Real "Bill The Butcher" William Poole was a Nativist enforcer of The Native American Party, also known as The Know Nothing Party, which was a faction of the American Republican Party. The Know Nothing was a movement created by Nativists whom believed that the overwhelming immigration of German and Irish Catholic immigrants were a threat to republican values and controlled by the Pope in Rome. They were dubbed the Know Nothings by outsiders of their semi-secret organization. This had nothing to do with them knowing anything. It had to do with their reply when asked of the organization's activities, often stating, "I know nothing." Bill the Butcher was a leader of The Bowery Boys and known for his skills as being a good bare knuckle boxer. Poole's trade was that of a butcher, and was infuriated when many butchering licenses were being handed out to Irish immigrants. William Poole was born in Sussex County, New Jersey to parents of English protestant descent. His family moved to New York City in 1832 to open a butcher shop in Washington Market, Manhattan. Bill Poole trained in his father's trade and eventually took over the family store. In the 1840s, he worked with the Howard (Red Rover) Volunteer Fire Engine Company #34, Hudson & Christopher Street. Uunlike in the movie, William "The Butcher" Poole was shot in real life. However, he was shot at Stanwix Hall, a bar on Broadway near Prince. William Poole did not die in a glorious street battle against his Irish enemies. Instead, he died from the gun wound at his home on Christopher Street. His last words were: "Goodbye, boys. I die a true American." What was true in the movie was the conflict the real Bill The Butcher had with the Irish immigrant gang the Dead Rabbits. The Dead Rabbits were William Poole's The Bowery Boys most hated enemy, and the leader of the Dead Rabbit's was Bill The Butcher's most hated archenemy. .
