Explanation:

After the American Civil War ended, the 14th Amendment to the U.S. Constitution addressed citizenship rights and equal protection under the law to all people. The reason behind this amendment was to solve the issues concerning former slaves and reconstruct the South after the war. Although the amendment had the intention to guarantee freedom to former slaves, this premise totally faded by state laws and federal court decisions after the Reconstruction Era ended following the Compromise of 1877, an unwritten deal between Republicans and Democrats that resulted in a withdrawal of federal troops from all Southern states allowing slaveholders to be elected to office. Thus, the scenario was set to facilitate the entrance of the Separate-but-equal doctrine, which did not violate the 14th amendment but it never brought equal protection under the laws to all people. This unleashed a series laws called Jim Crow Laws that made a separation between white and African American populations like the separation of the educational system, bathrooms, public transportation, restaurants and other areas of the American life. These restricted areas to the African American were of lower quality, therefore the inequality was quite evident making racial segregation common.
