Nine African-American students enter the all white Central High School in Little Rock, Arkansas, under heavily armed guard. In 1954, the U.S. Supreme Court ruled that racial segregation in public educational facilities was unconstitutional. In 1957, the first major confrontation over this decision came when African-American students attempted to integrate Central High School. Governor Orval Faubus surrounded the school with Arkansas National Guard troops, and a showdown with federal officials ensued. On September 24, President Dwight Eisenhower sent 1,000 U.S. troops to Little Rock. The next day, the African-American students entered the school for the first time. The episode served as a catalyst for the integration of other segregated schools in the United States.
