It seems to me that the KKK had about three stretches of considerable power: in the south during Reconstruction; in the south with some considerable influence in Pennsylvania, the Midwest, and as far as Colorado, during the 1920s; and again mostly in the south in the 1950s and 1960s.
After Reconstruction, the KKK essentially won--no black votes, no black officials. In the 1920s, I think it reduced itself to absurdity, with a high official jailed under the Mann Act. And law enforcement, notably the FBI, had a good deal to do with the end of its 1960s power.
