How did the little rock nine help integration?

the little rock nine were one of the first black students to go to an all white school in Little Rock Arkansas. by the end of the year, the 9 students dwindled down to 8, one had to transfer, and the others were stabbed, attacked, and bullied, but they did not give up on their goal, and Ernest Green became the first black to graduate Central High School. Unfortunately the school was closed down after that year.
