The document discusses key events and figures in the civil rights movement from 1954 to 1956. It covers the Brown v. Board of Education Supreme Court ruling that declared segregated public schools unconstitutional, the murder of Emmett Till, and the Montgomery bus boycott led by Martin Luther King Jr. and the Montgomery Improvement Association. The boycott lasted over a year and resulted in the desegregation of public buses in Montgomery, increasing King's national profile and support for nonviolent protest as an effective tactic.
