Verified Answer :

The main goal of the Ku Klux Klan during Reconstruction was to "prevent African Americans from exercising their rights" since they wanted blacks to stay under whites. 

Answer:

The KKK was basically an organization in which white supremacists could join in order to interfere with African Americans’ rights, as they supported racism and thought whites were superior to African Americans. Because of this they didn’t like that African Americans were given rights.
