President Truman signs Executive Order 9981, which states, "It is hereby declared to be the policy of the President that there shall be equality of treatment and opportunity for all persons in the armed services without regard to race, color, religion, or national origin."
The Supreme Court rules on the landmark case Brown v. Board of Education of Topeka, Kans., unanimously agreeing that segregation in public schools is unconstitutional. The ruling paves the way for large-scale desegregation. The decision overturns the 1896 Plessy v. Ferguson ruling that sanctioned "separate but equal" segregation of the races, ruling that "separate educational facilities are inherently unequal." It is a victory for NAACP attorney Thurgood Marshall, who will later return to the Supreme Court as the nation's first black justice.
Fourteen-year-old Chicagoan Emmett Till is visiting family in Mississippi when he is kidnapped, brutally beaten, shot, and dumped in the Tallahatchie River for allegedly whistling at a white woman. Two white men, J. W. Milam and Roy Bryant, are arrested for the murder and acquitted by an all-white jury. They later boast about committing the murder in a Look magazine interview. The case becomes a cause célèbre of the civil rights movement.
(Montgomery, Ala.) NAACP member Rosa Parks refuses to give up her seat at the front of the "colored section" of a bus to a white passenger, defying a southern custom of the time. In response to her arrest the Montgomery black community launches a bus boycott, which will last for more than a year, until the buses are desegregated Dec. 21, 1956. As newly elected president of the Montgomery Improvement Association (MIA), Reverend Martin Luther King, Jr., is instrumental in leading the boycott.
