31 mar 1957 ano - 1957: Central High School, Little Rock, Kansas (After the federal district court ruled that the high school must be desegregated, Governor Orval Faubus deployed the National Guard in order to bar the entry of the nine blackstudents that were set to attend. Annoyed by what he saw as Faubus' dereliction of duty, having disobeyed the court ruling, President Eisenhower used his authority as Commander-in-chief to send 10,000 paratroopers to the school to ensure its integration.)
