The New Orleans Saints were founded by John W. Mecom Jr., David Dixon, and the city of New Orleans on November 1, 1966, the Saints joined the NFL as an expansion team in 1967. They are named after the jazz music heritage of New Orleans and the spiritual hymn "When the Saints Go Marching In".
The Saints were among the NFL's least successful franchises in their first several decades, where they went 20 consecutive seasons without a winning record or qualifying for the playoffs. They earned their first winning record and postseason berth in 1987, while their first playoff win would not occur until 2000, their 34th season. The team's fortunes improved amid the 21st century, which saw them become more consistent postseason contenders. Their greatest success to date came in the 2009 season, when they won Super Bowl XLIV, the team's first Super Bowl appearance. The Saints are one of two NFL franchises to win their sole Super Bowl appearance, along with the New York Jets, and the most recent to do so.
