The Ku Klux Klan became the largest and most powerful white supremacy group.
Step-by-step explanation:
White supremacy is the racialist idea that white people are superior to people of other cultures and therefore should be ruling over them. White supremacy has origins in the now-discredited theory of scientific segregation and often relies on pseudoscientific reasons.
The Ku Klux Klan started as a vigilante organization of previously associated soldiers trying to frighten once slaves and other blacks after the Civil War. The society recognizes itself today as a Christian “civil rights for whites” organization. Loyal White Knights are one of the greatest and most powerful Klan groups in the United States.
