What are two ways that white supremacy was restored in the south after the Civil War?

Two ways that white supremacy was restored in the South
after the Civil War were through governmental action and through
terrorism.

The terrorism was conducted by groups like the
Ku Klux Klan.  This group was created to try to frighten freed blacks and the white
supporters of Reconstruction governments.  The KKK used violence to try to prevent these
groups from exercising their political rights.

Partly
because of this, and partly because of Northern indifference, the Compromise of 1877 was
reached.  This compromise ended Reconstruction and allowed the South to have
self-government again.  Governments elected after this were uniformly white supremacist,
taking away the rights of black people to vote and to have equal
treatment.
