Answer:
violence broke out, and President Eisenhower sent in federal troops.
Step-by-step explanation:
The Brown v. Board of Education of Topeka was a landmark litigation or court case between Oliver Brown and the Board of Education in which the justices of the Supreme Court unanimously ruled (9-0) in 1954 that racially segregating children in public schools was unconstitutional because it violates the Equal Protection Clause of the Fourteenth Amendment (14th) of the Constitution of the United States of America.
Meanwhile, on the 4th of September, 1957, the first day of resumption of class activities at Central High School, the Governor of Arkansas, Orval Eugene Faubus invited the Arkansas National Guard to block all African-Americans (black) students from entering into the school.
In response to the court-ordered desegregation of Central High School in Little Rock, Arkansas violence broke out, and President Eisenhower sent in federal troops.
