Answer:
The KKK hoped to maintain the supremacy of the white people in the postwar South.
Explanation:
"KKK" stands for "Ku Klux Khlan." The Radicals (Republicans) wanted to secure the rights of the former slaves during the Reconstruction period. However, some people greatly opposed to it and created an invisible empire (KKK) that targeted the African Americans. They tried to terrorize them in order to ensure that the whites were still the ones holding the supreme power over all.
