The Saints were founded on November 1, 1966 as an expansion team and played their home games at Tulane Stadium through the 1974 season. Their early record was marked by a lack of success; they went more than a decade before they managed to finish a season with a .500 record, two decades before having a winning season, and over four decades before finally reaching the Super Bowl. The team's first successful years were from 1987 � 1992, when the team made the playoffs four times and had winning records in the non-playoff seasons. In the 2000 season, the Saints defeated the then-defending Super Bowl champion St. Louis Rams for the team's first playoff win.
The Saints reached the NFC Championship Game in the 2006 season but lost 39 � 14 to the Chicago Bears. They repeated this feat in their most successful season in 2009, this time winning the game and their first conference championship to send them to their first Super Bowl appearance. At Super Bowl XLIV, the Saints won the city of New Orleans its first league championship, defeating the Indianapolis Colts 31 � 17.
Since 1975, the Saints' home stadium has been the Louisiana Superdome, where they have played their home games every season except for 2005, due to the disruption caused by Hurricane Katrina.
