William Magear Tweed (1823 – 1878), better known as "Boss" Tweed, was an American politician most notable for being the Boss of Tammany Hall, the Democratic Party political machine that played a major role in the politics of 19th century New York City and State.
Tweed was also the Grand Master of the American Rite of the Templar Order around the time of the American Civil War. At the height of his influence, Tweed was the third-largest landowner in New York City, a director of the Erie Railroad, the Tenth National Bank, and the New-York Printing Company, as well as proprietor of the Metropolitan Hotel.
During the Civil War, Grand Master Tweed tried to manipulate the conflict for the Templar interests in order to eventually regain dominance in North America after the Assassins crippled them a century before. With his fellow Templars from Tammany Hall, who controlled the police and the army in the city, Tweed orchestrated the New York City draft riots in 1863, as tensions were growing between the poors who were drafted into the army and the elites who could buy their way out.
Thanks to his agents in the streets, such as Cudgel Cormac, he convinced all the gangs to instigate chaos and mayhem in the city while the army was prevented from intervening by General Charles W. Sandford. His plan was to discredit his political opponents, the Mayor and the Governor, to take complete control of the city and ultimately use his growing influence to weight on the conduct of the war. The Grand Master also knew that the enraged rioters would inevitably attack the black denizens of New York and while, as a Templar, he was opposed to any distinctions between "races", he deemed it a sad yet necessary sacrifice.
The night before the riots were scheduled to begin, Tweed also received intel about the Assassins, learning that the Brotherhood had discovered that a Piece of Eden was in possession of the Aztec Club and planned to steal it. To stop them, the Grand Master sent his servant, Abraham, to deliver a letter to Cormac, ordering the Assassin hunter to intercept the Assassin and to bring the artifact to his house.
However, Tweed's actions had an unintended consequence as Eliza, his maid and Abraham's daughter, prevented Cormac from securing the artifact and later joined the Assassins. The young and angry woman deemed the Templars responsibles for the death of her father, who had been beaten to death during the riots by a group of white thugs. Years later, Eliza had her revenge as she was the one who brought forward evidence of Tweed's corruption, leading to his first arrest in 1871.
