The Arizona Cardinals are a professional American football team with headquarters based in Tempe, AZ. They are currently members of the West division of the National Football Conference (NFC) in the National Football League (NFL). The Cardinals were founded in 1898, and are the oldest continuously run professional football team in the United States.
The team was established in Chicago in 1898 and was a charter member of the NFL in 1920. Along with the Chicago Bears, the club is one of two NFL charter member franchises still in operation since the league’s founding. (The Green Bay Packers were an independent team until they joined the NFL in 1921). The club then moved to St. Louis, Missouri in 1960 and played in that city through 1987 (sometimes referred to as the “Football Cardinals” or the “Big Red” to avoid confusion with the Major League Baseball St. Louis Cardinals). Other less commonly used nicknames were the “Gridbirds” (used only by a local newspaper columnist) or “Cardiac Cards” (used only to refer to the 1975 team). Before the 1988 NFL season, the team moved to Tempe, Arizona, a college suburb east of Phoenix, and played their home games for the next 18 years at Arizona State University’s Sun Devil Stadium. In 2006, the club began playing all home games at the newly constructed University of Phoenix Stadium in the northwestern suburb of Glendale, although the team’s training facility is in Tempe.
