Gangs of New York(2002)|The Dead Rabbits vs The Natives

At the beginning of the movie Gangs of New York, two gangs come together for a brutal fight:
The Dead Rabbits - led by "Priest" Vallon. This gang represented Irish immigrants and fought against the discrimination they faced, advocating for the rights of the newcomers.
The Natives - led by Bill "The Butcher" Cutting. They were anti-immigrant and represented the interests of those born in America, defending their claim to the city.
This battle symbolizes the deep conflict between immigrants and native-born Americans in 19th-century New York.
