Answer:
use of terrorism to prevent African Americans from voting.
Explanation:
Even after the End of the Civil War, many Southerners feel humiliated and there was a sense of dominance of the Republicans. Therefore these groups formed in the South to overthrow the Republicans by organizing violent methods to stop African Americans from voting. They were against the amalgamation of the races and want to restore the old cultural patterns in which the white enjoyed a superior status.
