The sentences that tell methods whites used to keep blacks from exercising their rights are the following: they passed "black codes" after the Civil War that made free blacks little more than slaves, they formed hate groups, such as the Ku Klux Klan, to terrorize blacks, and they started a "separate but equal" policy to keep the races apart.
Although the abolition of slavery took effect after the Civil War, President Abraham Lincoln gave the Southern States leeway to proceed with their own Reconstruction process. White people in the South took their own measures and restricted the rights of black people in public places and public services, created the black codes, and violently attacked or intimidated African Americans through groups such as the Ku Klux Klan.
