Civil Rights laws aim to guarantee equal treatment and political participation for all citizens regardless of race. The Supreme Court struck down the "separate but equal" doctrine in Brown v. Board of Education in 1954, reversing the earlier Plessy v. Ferguson decision. Subsequent Civil Rights Acts in 1964 and 1965 banned discrimination in public accommodations, employment, and voting. The Nineteenth Amendment gave women the right to vote. Later court cases and laws extended civil rights protections to other groups such as prohibiting sexual harassment and advancing LGBTQ rights.
