Historic Moments Of The Civil Rights Movement

A black student, Nathaniel Steward, 17, recites his lesson on May 21, 1954, at the Saint-Dominique school in Washington, D.C. The school was among the first to hold integrated classes of black and white students following Brown v. Board of Education, the Supreme Court decision outlawing school segregation.

Lawyers Thurgood Marshall (center), George E.C. Hayes (left), and James Nabrit celebrate the Supreme Court's decision in Brown v. Board of Education on May 17, 1954. The ruling declared racial segregation in schools to be unconstitutional. In 1967, Thurgood Marshall became the first African-American to be appointed to the Supreme Court.

Emmett Till, a 14-year-old from Chicago, was visiting family in Mississippi when he was kidnapped, brutally beaten, shot, and dumped in a river. His two white attackers, who said that they had killed Till because he whistled at a white woman, were acquitted by an all-white jury. The case became a cause célèbre of the civil rights movement.

Civil rights activist Rosa Parks, pictured with Dr. Martin Luther King Jr. in 1955. Parks was arrested for refusing to give up her seat on a bus to a white passenger. Her act of civil disobedience marked the beginning of the Montgomery Bus Boycott, a protest campaign against segregation on public transport in the state of Alabama.

Rosa Parks sits with a journalist in the front of a bus in Montgomery, Alabama, in 1956, after the U.S. Supreme Court ruled segregation illegal on the city's transport system. The court case was the result of the bus boycott initiated by Parks and fellow activists.

Nine black children are escorted by U.S. paratroopers outside a school in Little Rock, Arkansas, on September 25, 1957. U.S. President Dwight D. Eisenhower had ordered government troops to protect the children from angry protesters as they began attending a white-majority school. The state's governor, Orval Faubus, had ordered the state militia to bar the children from entering the school.

The campaign continued under new leadership after King's assassination in April 1968.
