Did the KKK only aim to attack African -Americans? Yes or no?Explain?

No.While African Americans were the primary target of the Ku Klux Klan's terror and violence, they also targeted other groups they deemed undesirable. These included, but were not limited to, white Republicans (especially during Reconstruction), Jewish people, Catholic people, immigrants, and those suspected of being communists or socialists. The Klan's ideology was based on white supremacy and nativism, leading them to persecute anyone who didn't fit their narrow definition of an acceptable American.
