Under Eisenhower’s leadership, the United States saw the end of the Korean War, the construction of the interstate highway system, and the beginnings of desegregation in the South. In 1957, he dispatched federal troops to Little Rock, Arkansas, to protect African American students after the desegregation of Central High School. It was the first time since Reconstruction that a president sent military forces into the South to enforce federal law. That same year, he signed a federal law granting protection for voting rights.
