Context paragraphs:
Glenn E. Smiley: Glenn Smiley (April 19, 1910 – September 14, 1993) was a white civil rights consultant and leader.  He closely studied the doctrine of Mahatma Gandhi and became convinced that racism and segregation were most likely to be overcome without the use of violence, and began studying and teaching peaceful tactics.  As an employee of the Fellowship of Reconciliation (FOR), he visited Martin Luther King, Jr. in Montgomery, Alabama in 1956 during the Montgomery bus boycott where Smiley advised King and his associates on nonviolent tactics, and was able to convince King that nonviolence was a feasible solution to racial tension.  Smiley, together with Bayard Rustin and others, helped convince King and his associates that complete nonviolence and nonviolent direct action were the most effective methods and tools to use during protest.  After the Civil Rights Movement, Smiley continued to employ nonviolence and worked for several organizations promoting peace in South American countries.  Just three years before him 1993 death, Smiley opened the King Center in Los Angeles.

Women's Political Council: The Women's Political Council, founded in Montgomery, Alabama, was an organization that was part of the Civil Rights Movement that was formed to address the racial issues in the city.  Members included Mary Fair Burks, Jo Ann Robinson, Irene West, Thelma Glass, and Uretta Adair.  The WPC was the first group to officially call for a boycott of the bus system during the Montgomery Bus Boycott, beginning in December 1955.  The group led efforts in the early 1950s to secure better treatment for Black bus passengers, and in December 1955 it initiated the thirteen month bus boycott.  They helped organize communications to get it started, as well as to support it, including giving people rides who were boycotting the buses.  The African Americans of Montgomery upheld the boycott for more than a year.

E. D. Nixon: Edgar Daniel Nixon (July 12, 1899 – February 25, 1987), known as E. D. Nixon, was an African-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.

Septima Clark's work was commonly under appreciated by Southern male activists.  She became known as the "Queen mother" or "Grandmother" of the Civil Rights Movement in the United States.  Martin Luther King, Jr. commonly referred to Clark as "The Mother of the Movement".  Clark's argument for her position in the Civil Rights Movement was one that claimed "knowledge could empower marginalized groups in ways that formal legal equality couldn't."

As president of the SCLC, he led the Poor People's Campaign in Washington, D.C. during 1968.  Abernathy also served as an advisory committee member of the Congress on Racial Equality (CORE).

The campaign lasted from December 5, 1955—the Monday after Rosa Parks, an African American woman, was arrested for refusing to surrender her seat to a white person—to December 20, 1956, when a federal ruling, "Browder v. Gayle", took effect, and led to a United States Supreme Court decision that declared the Alabama and Montgomery laws requiring segregated buses to be unconstitutional.

Alabama Chapter of the Communist Party USA: The Alabama Chapter of the Communist Party USA (CPUSA) was one of the most influential political bodies organizing poor African-Americans in the South during and after the Great Depression.  Started with just two members, the Alabama chapter CPUSA was established in Birmingham Alabama in 1928, and remained active until it was forced underground by Ku Klux Klan (KKK) and police repression, and was disbanded when it was outlawed in 1951.  During the height of Jim Crow and the Great Depression, the Alabama CPUSA organized some of the poorest African-American communities in the country, and was successful in leading organization drives in multiple industries including the Sharecroppers' Union, mine, mill, and industrial workers, as well as leading numerous campaigns to organize unemployed workers.  The Alabama CPUSA also played a vital role in organizing African-Americans during a period where many activists would later become leaders of the emerging Civil Rights Movement.  Ashbury Howard, who later was a significant leader in Alabama during the Civil Rights Movement, and Rosa Parks, who would later commit an act of civil disobedience launching the Montgomery Bus Boycott, were both trained and active with the Alabama CPUSA.
