How did the Ku Klux Klan most often suppress the rights of others?

according to what i read on a book the Ku Klux Klan was made when South America losed the War with Norht America and the North America made liberty to the black slaves (ahem do not mind the racism), after that the slaves became like some kind of rogues and began attaking and robbing people, some robbed for food to sustain family and others because they want to, then there is when the Ku Klux Klan (also known as KKK) came and attaked or killed those freed black slave wiping them out.
