As nine black students walked toward the front doors of Little Rock Central High School in 1957, accompanied by federal troops from the 101st airborne division, each step they took defied social norms and challenged discrimination.

Last night, almost a half of a century later, Carlotta Walls LaNier, the youngest of the students known as the "Little Rock Nine," retold her courageous story to an eager crowd of about 500 in Eisenhower Auditorium. LaNier provided the keynote address for the Martin Luther King Jr. evening celebration.

LaNier spoke fondly of King and his accomplishments.

"He was a visionary. He believed in equality for all people," she said. "He was a deeply spiritual man who set the pace for social change."

She also described him as a brave and inspirational person, without whom civil rights progress might not have been possible. "He gave us hope. He gave us a promise for a better tomorrow," she said.

LaNier also spoke of her struggle with racist classmates and teachers and described stories of her abuse. She recounted the solidarity she and the other nine students shared, and the pride they now have for overcoming discrimination.

She also showed an emotional video of the group receiving the highest civilian award, the Congressional Gold Medal, from President Clinton in 1999.

LaNier closed her address by expressing her pride for the civil rights progress the nation has made. She discussed her own involvement in the Little Rock Nine Foundation, which provides students with scholarships and mentoring programs, and encouraged students to also stand strong in the battle for equality.

The ASHE Theatre Company, the Orchesis, Tapestry and NOMMO dance companies and Essence of Joy also provided vocal and dance performances at the celebration.
