The Ku Klux Klan (KKK) is a white supremacist hate group founded in the United States in the aftermath of the Civil War, specifically in 1865. The Klan is known for promoting racism, anti-Semitism, and xenophobia, often using violence and intimidation to achieve its goals. Its members typically wear distinctive white robes and hoods, symbolizing their beliefs and anonymity. Throughout its history, the KKK has been involved in various acts of terrorism, including lynchings and bombings, particularly targeting African Americans and other minority groups. The organization has experienced several revivals, with its influence peaking in the 1920s and again in the 1960s during the Civil Rights Movement.
