Bro America's first blockbuster movie is about the Ku Klux Klan saving the day, specifically saving white women from "bad and evil" black men. The only thing is that I can't remember the name of the movie. But if you're interested in watching something quite interesting that came from the periods after the civil war, watch a movie called "the terror of tiny town". It's like the most racist movie you'll ever see about small people wrangling other small people and the good guys where white hats and the bad guys wear black. My history teacher said he loved it (honestly a little concerning yet funny at the same time).
