The Arizona Cardinals are a professional American football team. They currently are members of the Western Division of the National Football Conference in the National Football League. The Cardinals were founded in 1898, and are the oldest continuously run professional American football club 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 club then moved to St. Louis, Missouri in 1960 and played in that city through 1987. Other less commonly used nicknames were the "Gridbirds" or "Cardiac Cards". Before the 1988 NFL season, the team moved to Tempe, Arizona, a college town suburb 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, an eastern suburb.
