The Dallas Cowboys joined the NFL in 1960 as an expansion team. Since their inception, they have been one of the most decorated teams in the National Football League. They have appeared in the Super Bowl 8 times and have won 5 times. Their 5 Super Bowls is good enough to put them at second all time (tied with New England and San Francisco) just behind the Pittsburgh Steelers. The Cowboys are also the only NFL team in history to have 20 straight winning seasons (1966-1985).
