Practically nothing in the history of the United States has suffered from myth-making and misunderstanding as much as the history of race relations and racist violence. The history Ku Klux Klan is no exception. This is ironic. In its various incarnations, the KKK was supposed to be a secret organization. But historians know a great deal about it, and have analyzed it deeply. We explain the three periods of KKK, how each version of the Klan was different, but also how each version had one crucial thing in common -- hate. Listen, learn, and contemplate.
