The Civil Rights Movement from 1954-1964 saw major developments in desegregation and voting rights. Key events included the Brown vs Board of Education Supreme Court ruling in 1954 declaring segregation unconstitutional, the Montgomery Bus Boycott led by Martin Luther King Jr in 1955-1956, the use of sit-ins and freedom rides to challenge segregation, and violence against advocates like the murder of Medgar Evers in 1963 which helped build support for new civil rights legislation.
