The "Ku Klux Klan" name was used by numerous independent local groups opposing the civil rights movement and desegregation, especially in the 1950s and 1960s. During this period, they often forged alliances with Southern police departments, as in Birmingham, Alabama; or with governor's offices, as with George Wallace of Alabama. Several members of Klan groups were convicted of murder in the deaths of civil rights workers in Mississippi in 1964 and of children in the bombing of the 16th Street Baptist Church in Birmingham in 1963.
