The network of terror cells that sprang up during Reconstruction went by many names, including the White League, the White Knights, the Knights of the White Camellia, and—the most famous of all—the “Circle of Brothers,” otherwise known as the Ku Klux Klan. It was insurrection, ethnic cleansing, and terrorism with a little bit of guerrilla warfare mixed in for good measure. To enforce their goals, the loose confederation of historically white fraternities all had one common strategy: killing as many Black people as possible and overthrowing the government that had enabled their freedom.
