Ku Klux Klan (KKK)
Members of the Ku Klux Klan were responsible for hundreds of acts of violence in the decades since their start. During the height of the Civil Rights movement, KKK members firebombed churches and civil right leaders’ homes. The bombings killed prominent civil right leader Harry Tyson Moore and his wife, and four little girls in Birmingham, Alabama. The KKK also murdered James Chaney, Andrew Goodman and Michael Schwerner during Freedom Summer in 1964.
Over the years, the influence and membership of the KKK has waned as they have affiliated with more powerful and organized white supremacist groups. Today, the KKK has an estimated 5,000 to 8,000 members.
