1 The Klu Klux Klan
Ku Klux KlanBy far the most notorious organization on this list, the Klu Klux Klan has been wreaking havoc since 1865 with the end of the United States Civil War. Founded by Confederate veterans, the group sought to restore white supremacy by assaulting freed slaves and those that aided them. They assassinated prominent African Americans, including politicians, religious figures, and community leaders.Today, the Klu Klux Klan focuses on illegal immigrants, homosexuals, urban criminals, and African Americans. The Klan laid forth the groundwork for nearly every white supremacist group that exists today, and as such should be held accountable for their actions as well. This includes the murder and assault of thousands of individuals throughout their history, and frequent property crimes against minority households.
