Answer
Jim Crow Laws were legalized by the Supreme Court's ruling in Plessy v. Ferguson (1896). These laws enforced racial segregation in the southern U.S. until the landmark case Brown v. Board of Education in 1954. Jim Crow Laws mandated the separation of public facilities and accommodations based on race, including transportation, schools, restrooms, and restaurants. This legalized segregation perpetuated discrimination and unequal opportunities for African Americans.
