In 1846, in Lower Manhattan’s Five Points, a territorial war between the “Natives” (those born in the United States) and recently arrived Irish Catholic immigrants, is coming to a head in Paradise Square. The Natives are led by Bill “the Butcher” Cutting, a Protestant nativist. The leader of the Irish gang, the Dead Rabbits, is known as “Priest” Vallon. The gangs meet in a bloody battle, concluding when Cutting kills Vallon, witnessed by Vallon’s young son, Amsterdam. Cutting declares the Dead Rabbits outlawed but orders Vallon’s body be buried with honor. Amsterdam seizes the knife used to kill his father, races off, and buries it along with a medal his father gave him depicting St. Michael the Archangel.
In September 1862, Amsterdam Vallon returns to New York. Arriving in Five Points, he reunites with an old friend, Johnny Sirocco, who introduces Amsterdam to Cutting. Amsterdam finds many of his father’s old loyalists are now under Cutting’s control: Happy Jack Mulraney is a corrupt city constable in Cutting’s pocket, and the racist McGloin is one of Cutting’s lieutenants. Amsterdam works his way into Cutting’s inner circle, and learns that each year, on the anniversary of the Five Points battle (February 16), Cutting leads the city in saluting the victory over the Dead Rabbits. Amsterdam makes plans to kill Cutting during this ceremony, in order to exact public revenge, later meeting Jenny Everdeane, a successful and discreet pickpocket and grifter. His interest in her is dampened, however, once he learns she was Cutting’s ward and still enjoys Cutting’s affections. Amsterdam becomes a part of Boss Tweed’s empire. After so long of having these connections, he then attempts to assasinate The Butcher, but fails. And has to recover after being brutally mutilated. Once he does recover, he assumes leadership over the Dead Rabbits, and leads them to victory over another battle with The Natives.
Now to divulge on the term “gang”. Between current society, and the old society. Currently now, the term “gang” is depicted as a bunch of thugs, set on crimes and nothing good. They also have territories. And leaders, with ranks and such. Kind of like how it was back then. But it’s much different from then now.
Back then, it seems to have been more of a clan, and it’s set on heritage. But they weren’t hell bent on crime like they currently are now. They’re as corrupt as they ever were, and they bribed the police and the city ranks. But they’re usually neutral, but against another clan, they’re very hostile. And defensive.
