The Cowboys Redskins rivalry is a sports rivalry between two professional American football teams in the National Football League (NFL), the Dallas Cowboys and the Washington Redskins. Sports Illustrated has called it the top NFL rivalry of all time and "one of the greatest in sports". The two franchises have won 31 combined division titles and ten NFL Championships, including eight combined Super Bowls.The rivalry started in 1960 when the Cowboys joined the league as an expansion team. During that year they were in separate conferences, but played once during the season. In 1961, Dallas was placed in the same division as the Redskins, and from that point on, they have played each other twice during every regular season.
