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