Why were federal troops sent to Little Rock Arkansas in 1957?

Federal troops were sent to Little Rock, Arkansas, in 1957 to enforce the integration of Central High School, following a court order that mandated the admission of nine African American students, known as the Little Rock Nine. The governor of Arkansas, Orval Faubus, opposed this integration and deployed the National Guard to block the students' entry. President Dwight D. Eisenhower responded by federalizing the National Guard and sending troops to ensure the students could safely attend the school, highlighting the federal government's commitment to uphold civil rights. This event became a significant moment in the Civil Rights Movement, symbolizing the struggle against segregation.
