In the 1896 case of Plessy v. Ferguson, the Supreme Court ruled that the Louisiana legislature's law requiring separate but equal accommodations for black and white residents did not violate the Constitution. However, several later cases have expanded the scope of the Fourteenth Amendment's Equal Protection Clause, including Griswold v. Connecticut, Loving v. Virginia, Roe v. Wade, Lawrence v. Texas, Brown v. Board, and Sims v. Sims. These cases have challenged segregation and discrimination in various aspects of public life, such as education and access to services. Overall, the Fourteenth Amendment has been used to protect individuals from discrimination based on race, sex, and other characteristics.
