When did the KKK form?
<|assistant|>
The Ku Klux Klan was founded in 1865 by ex-confederate soldiers in the aftermath of the American Civil War in order to oppose Reconstruction efforts and to restrict the rights of former slaves. The organization experienced its highest levels of success in the late 19th and early 20th centuries.
