Report of The Joint Committee to Inquire into the Conditions of Affairs in the Late Insurrectionary States, vols. 1–5, 1871
The Joint Committee that investigated the Ku Klux Klan released its report in 1871. The thirteen volumes described Klan violence against African Americans in seven Southern states. It persuaded President Ulysses S. Grant to launch a vigorous campaign against the Ku Klux Klan, nearly destroying the organization as it was then constituted.

The Ku Klux Klan
After the Thirteenth Amendment abolished slavery in 1865, those opposed to freedom for African Americans found other means of control. Southern states implemented restrictive laws known as Black Codes, and armed vigilantes formed the Ku Klux Klan and used violent intimidation. Several congressional committees investigated the Klan, and Congress passed the Enforcement Act of 1870 to protect freedmen against violence. A Joint Committee to Inquire into the Conditions of Affairs in the Late Insurrectionary States formed in 1871 and exposed the Klan’s tactics, hastening a decline that lasted until the 1920s.
