In the decades after its adoption, the equal protection clause was cited by a number of African American activists who argued that racial segregation denied them the equal protection of law. However, in 1896, the U.S. Supreme Court ruled in Plessy v. Ferguson that states could constitutionally provide segregated facilities for African Americans, so long as they were equal to those afforded white persons. The Plessy v. Ferguson decision, which announced federal toleration of the so-called “separate but equal” doctrine, was eventually used to justify segregating all public facilities, including railroad cars, restaurants, hospitals, and schools. However, “colored” facilities were never equal to their white counterparts, and African Americans suffered through decades of debilitating discrimination in the South and elsewhere. In 1954, Plessy v. Ferguson was finally struck down by the Supreme Court in its ruling in Brown v. Board of Education of Topeka.
