Hello.

The Southern Christian Leadership Conference is an African American civil rights organization which first president was Martin Luther King. Its main purpose was to "gain full equality for African Americans". For example, they wanted to end with segregation in bus systems in the South, and later on expanded its focus to all kinds of segregation. Also I would choose "organize a large march on Washington" since this organization played a major role in the March on Washington for Jobs and Freedom, there Martin Luther King gave an speech.

Hope this helps.
