The Klu Klux Klan was founded by former Confederate Army officers in Tennessee in 1866.

Explanation:

The Ku Klux Klan is a racist and violent secret society, especially active in the southern United States. The clan was active as a unitary organization from 1865 to 1875 and from 1915 to 1944. Since 1950 there have been several independent groups under this name.

It was founded by several former Confederate officers in December 24, 1865, and its primary goal was to oppress the blacks in the south. Its acts of violence were initially directed against blacks and their protectors as well as against the numerous northern settlers who wanted to benefit from the reconstruction of the south after the Civil War. It was a paramilitary group that tried to achieve its political goals with terror and violence and was dissolved around 1870. The clan was re-established in 1915 as a nativist mass organization.
