Then came the black students' first day of school. The Governor of Arkansas called out soldiers from the Arkansas National Guard to prevent the black students from even entering the school. This was against a Supreme Court ruling, so President Dwight D. Eisenhower got involved. He took control of the Arkansas National Guard and ordered them to leave the school. Then he sent soldiers from the United States Army to protect the students. This was an important civil rights victory. It meant the federal government was willing to get involved and force states to end segregation in schools.
