During what period did the Jim Crow Laws become prominent in the United States?

The Jim Crow Laws became prominent in the United States during the Post-Reconstruction period, specifically in the late 19th century following the end of Reconstruction in 1877. This era was marked by the widespread establishment of laws and policies that enforced racial segregation and disenfranchised African Americans, especially in the Southern states. The aftermath of the Civil War and the Reconstruction era saw a backlash from many white Southerners against the advancements that had been made towards African American rights. As a result, Jim Crow Laws were adopted to maintain white supremacy and control over the Black population, institutionalizing inequalities through segregation in public facilities, schools, and transportation, as well as legal restrictions that limited voting rights.

Jim Crow Laws were fundamentally a response to the social and political changes brought about by Reconstruction and the civil rights progress made during that time. Thus, recognizing the context and timeline of these laws makes it clear that their prominence is firmly rooted in the Post-Reconstruction period.
