 After the decline of the national organization, small independent groups adopted the name "Ku Klux Klan", along with variations.They had no formal relationships with each other, or connection to the second KKK, except for the fact that they copied its terminology and costumes.Beginning in the 1950s, for instance, individual Klan groups in Birmingham, Alabama, began to resist social change and blacks' efforts to improve their lives by bombing houses in transitional neighborhoods.
