What organization wanted to keep African Americans from voting and fought the white rule?

The organization that sought to keep African Americans from voting and fought for white rule was the Ku Klux Klan (KKK). Founded in the aftermath of the Civil War, the KKK used intimidation, violence, and terror to suppress Black voter registration and participation, aiming to maintain white supremacy in the United States. Their efforts were part of broader systemic racism and discrimination during the Jim Crow era, which sought to disenfranchise African Americans and uphold segregation.
