The New Orleans Saints are a professional American football team based in New Orleans, Louisiana. The Saints currently compete in the National Football League as a member of the league's National Football Conference South division. The team was founded by John W. Mecom Jr., David Dixon, and the city of New Orleans on November 1, 1966. The Saints began play in Tulane Stadium in 1967. The name "Saints" is an allusion to November 1 being All Saints' Day in the Catholic faith. New Orleans has a large Catholic population, and the spiritual "When the Saints Go Marching In" is strongly associated with New Orleans and is often sung by fans at games. The franchise was founded on November 1, 1966. The team's primary colors are old gold and black; their logo is a simplified fleur-de-lis. They played their home games in Tulane Stadium through the 1974 NFL season. The following year, they moved to the new Louisiana Superdome. For most of their first 20 years, the Saints were barely competitive, only getting to .500 twice.
