Question: How many Super Bowls have the Saints won? Passage:The New Orleans Saints are a professional American football team based in New Orleans, Louisiana. They are a member of the South Division of the National Football Conference (NFC) in the National Football League (NFL). The NFL awarded the city of New Orleans the 16th franchise in the league in November 1, 1966, All Saints Day, five months after the 89th United States Congress approved the merger of the NFL with the American Football League (AFL) in June of that year. In January 1967, the team was given the current "New Orleans Saints" name, and began playing in their first season in September of that year. Since the franchise's creation, it has been based in New Orleans. The team's home games were originally played at Tulane Stadium from 1967 to 1974, it was demolished in 1979, when the team relocated its home games to its current stadium, the Mercedes-Benz Superdome (formerly Louisiana Superdome from 1975 to 2011).
