Segregation in sports in the United States was also a major national issue. In 1900, just four years after the US Supreme Court separate but equal constitutional ruling, segregation was enforced in horse racing, a sport which had previously seen many African American jockeys win Triple Crown and other major races. Widespread segregation would also exist in bicycle and automobile racing. In 1890, however, segregation would lessen for African-American track and field athletes after various universities and colleges in the northern states agreed to integrate their track and field teams. Like track and field, soccer was another which experienced a low amount of segregation in the early days of segregation. Many colleges and universities in the northern states would also allow African Americans on to play their football teams as well.
