Explain the importance of jim crows laws and how these laws contributed to segregation

Jim Crow laws were a revised form of the slave codes that were used to regulate enslaved people prior to 1865. The Jim Crow system relied on the doctrine of separate but equal, which was affirmed in Plessy v. Ferguson in 1896. These laws governed all aspects of interaction between African Americans and whites and extended to the social, economic, and political spheres. African Americans were denied basic civil rights (all of the nonpolitical rights of a citizens) as well as political rights (citizenship and the right to vote). They also endured segregated facilities in all aspects of public life from restaurants to educational institutions.
