The events of the Little Rock crisis.

We are talking about the terrible segregation times in the southern states of the United States. Specifically, in Little Rock, Arkansas, in 1957. The Little Rock Crisis started when nine African American students were prevented from entering the public school premises in Little Rock Central High School. State governor Orval Faubus gave the order. The decision made the news and generated consternation in many citizens. The decision tarnished the reputation of the state to the degree that President Dwight Eisenhower had to intervene to resolve the issue and the students could get access to the school.
