What was the mission of the ku klux klan?

The correct answer is: "to impose white supremacy in the US".

The Ku Klux Klan was a hate group from the United States which defended white supremacy and rejected inmigration flows through violent and terrorist actions (both physical assault and murder) against members of different racial groups and against anyone who tried to impede their activities.

KKK has been active during the different stages: first of all during the late 1860s, during the Reconstruction Era but died out soon in the early 1970s. It emerged again in the 1920s. Its final stage was in the 1950s as a response to the first manifestations of the Civil Rights movement.
