Explanation:

The NAACP’s legal strategy against segregated education culminated in the 1954 Supreme Court’s landmark Brown v. Board of Education decision. African Americans gained the formal, if not the practical, right to study alongside their white peers in primary and secondary schools. The decision fueled an intransigent, violent resistance during which Southern states used a variety of tactics to evade the law.

In the summer of 1955, a surge of anti-black violence included the kidnapping and brutal murder of fourteen-year-old Emmett Till, a crime that provoked widespread and assertive protests from black and white Americans. By December 1955, the Montgomery, Alabama, bus boycott led by Martin Luther King, Jr., began a protracted campaign of nonviolent civil disobedience to protest segregation that attracted national and international attention.

During 1956, a group of Southern senators and congressmen signed the “Southern Manifesto,” vowing resistance to racial integration by all “lawful means.” Resistance heightened in 1957–1958 during the crisis over integration at Little Rock’s Central High School. At the same time, the Leadership Conference on Civil Rights led a successful drive for passage of the Civil Rights Act of 1957 and continued to press for even stronger legislation. NAACP Youth Council chapters staged sit-ins at whites-only lunch counters, sparking a movement against segregation in public accommodations throughout the South in 1960. Nonviolent direct action increased during the presidency of John F. Kennedy, beginning with the 1961 Freedom Rides.

Hundreds of demonstrations erupted in cities and towns across the nation. National and international media coverage of the use of fire hoses and attack dogs against child protesters precipitated a crisis in the Kennedy administration, which it could not ignore. The bombings and riots in Birmingham, Alabama, on May 11, 1963, compelled Kennedy to call in federal troops.

On June 19, 1963, the president sent a comprehensive civil rights bill to Congress. The March on Washington for Jobs and Freedom on August 28 roused public support for the pending bill. After the president’s assassination on November 22, the fate of Kennedy’s bill was in the hands of his vice president and successor, Lyndon B. Johnson, and the United States Congress.
