Events of Little Rock nine were a part of the protests that led to end of segregation in schools.
Explanation:
The Little Rock Nine was a group of Black students who were to be enrolled to the school which is Little Rock Central High school in 1957.
This enrollment was followed by widespread controversy and led to the Little Rock crisis wherein some of the students were not allowed to enter the racially segregated school.
The students were prevented by the Governor of Arkansas but they eventually had to give in and let them study there.
