The Little Rock Nine were a group of nine African American students enrolled in Little Rock Central High School in 1957. Their enrollment was followed by the Little Rock Crisis, in which the students were initially prevented from entering the racially segregated school by Orval Faubus, the Governor of Arkansas. They then attended after the intervention of President Dwight D. Eisenhower.

The U.S. Supreme Court issued its historic Brown v. Board of Education, 347 U.S. 483, on May 17, 1954. Tied to the Fourteenth Amendment to the U.S. Constitution, the decision declared all laws establishing segregated schools to be unconstitutional, and it called for the desegregation of all schools throughout the nation. After the decision, the National Association for the Advancement of Colored People (NAACP) attempted to register black students in previously all-white schools in cities throughout the South. In Little Rock, Arkansas, the school board agreed to comply with the high court's ruling. Virgil Blossom, the Superintendent of Schools, submitted a plan of gradual integration to the school board on May 24, 1955, which the board unanimously approved. The plan would be implemented during the fall of the 1957 school year, which would begin in September 1957.

By 1957, the NAACP had registered nine black students to attend the previously all-white Little Rock Central High, selected on the criteria of excellent grades and attendance. Called the "Little Rock Nine", they were Ernest Green (b. 1941), Elizabeth Eckford (b. 1941), Jefferson Thomas (1942–2010), Terrence Roberts (b. 1941), Carlotta Walls LaNier (b. 1942), Minnijean Brown (b. 1941), Gloria Ray Karlmark (b. 1942), Thelma Mothershed (1940–2024), and Melba Pattillo Beals (b. 1941). Ernest Green was the first African American to graduate from Central High School.

When integration began on September 4, 1957, the Arkansas National Guard was called in to "preserve the peace". Originally at orders of the governor, they were meant to prevent the black students from entering due to claims that there was "imminent danger of tumult, riot and breach of peace" at the integration. However, President Eisenhower issued Executive Order 10730, which federalized the Arkansas National Guard and ordered them to support the integration on September 23 of that year, after which they protected the African American students.

One of the plans created during attempts to desegregate the schools of Little Rock was by school superintendent Virgil Blossom. The initial approach proposed substantial integration beginning quickly and extending to all grades within a matter of many years. This original proposal was scrapped and replaced with one that more closely met a set of minimum standards worked out in attorney Richard B. McCulloch's brief. This finalized plan would start in September 1957 and would integrate one high school: Little Rock Central. The second phase of the plan would take place in 1960 and would open up a few junior high schools to a few black children. The final stage would involve limited desegregation of the city's grade schools at an unspecified time, possibly as late as 1963.

This plan was met with varied reactions from the NAACP branch of Little Rock. Militant members like the Bateses opposed the plan on the grounds that it was "vague, indefinite, slow-moving and indicative of an intent to stall further on public integration." Despite this view, the majority accepted the plan; most felt that Blossom and the school board should have the chance to prove themselves, that the plan was reasonable, and that the white community would accept it.

This view was short-lived, however. Changes were made to the plan, the most detrimental being a new transfer system that would allow students to move out of the attendance zone to which they were assigned. The altered Blossom Plan had gerrymandered school districts to guarantee a black majority at Horace Mann High and a white majority at Hall High. This meant that, even though black students lived closer to Central, they would be placed in Horace Mann, thus confirming the intention of the school board to limit the impact of desegregation. The altered plan gave white students the choice of not attending Horace Mann, but did not give black students the option of attending Hall. This new Blossom Plan did not sit well with the NAACP and, after failed negotiations with the school board, the NAACP filed a lawsuit on February 8, 1956.

This lawsuit, along with a number of other factors, contributed to the Little Rock School Crisis of 1957.
