1871 Prohibition of the Ku Klux Klan in the United States
145 years ago, on October 12, 1871, U.S. President Ulysses Grant signed a law passed by Congress to ban the Ku Klux Klan, a racist organization that terrorized blacks and local authorities in the South. The law gave the president the power to revoke the right of personal immunity and resort to arms to uphold the laws, as "members of the Klan break into black homes to rob, rape, and kill law-abiding citizens." Nine counties in North and South Carolina were placed under state of siege.
