The document summarizes key events and organizations in the US civil rights movement from the late 19th century to the 1960s. It discusses the Supreme Court ruling in Plessy v. Ferguson that legalized "separate but equal" facilities, the 1954 Brown v. Board of Education ruling that deemed racial segregation in public schools unconstitutional, and influential civil rights organizations and protests like the Montgomery Bus Boycott, March on Washington, and Freedom Rides that fought against racial segregation and discrimination. The movement faced resistance but achieved several important victories through nonviolent protest and new civil rights laws that banned discrimination and expanded voting rights.
