E. D. Nixon and Rosa Parks lead the Montgomery bus boycott.

Edgar Daniel Nixon, known as E. D. Nixon, was an American civil rights leader and union organizer in Alabama who played a crucial role in organizing the landmark Montgomery bus boycott there in 1955. The boycott highlighted the issues of segregation in the South, was upheld for more than a year by black residents, and nearly brought the city-owned bus system to bankruptcy. It ended in December 1956, after the United States Supreme Court ruled in the related case, Browder v. Gayle (1956), that the local and state laws were unconstitutional, and ordered the state to end bus segregation.

Rosa Louise McCauley Parks was an American civil rights activist. She is best known for her refusal to move from her seat on a bus in Montgomery, Alabama, in defiance of Jim Crow racial segregation laws, in 1952, which sparked the Montgomery bus boycott. She is sometimes known as the "mother of the civil rights movement".

The Montgomery bus boycott was a political and social protest campaign against the policy of racial segregation on the public transit system of Montgomery, Alabama. It was a foundational event in the civil rights movement in the United States. The campaign lasted from December 5, 1955—the Monday after Rosa Parks, an African-American woman, was arrested for her refusal to surrender her seat to a white person—to December 20, 1956, when the federal ruling Browder v. Gayle took effect, and led to a United States Supreme Court decision that declared the Alabama and Montgomery laws that segregated buses were unconstitutional.
