How did the enforcement of jim crow laws after the civil war affect the lives of minority groups?

After the Civil War, the Jim Crow law affected the lives of minority groups in that it marginalized black Americans. It was based on black codes which were strict laws ruling how freed slaves would work and for how much salary. The codes also took voting rights away from black people, controlled how they traveled, how they lived, reduced them to servitude and got hold of the kids for labor services. This law was enforced for one hundred years, until 1968.
