<Li> State Farm Stadium (2006--present) </Li> <P> The Arizona Cardinals are a professional American football franchise based in the Phoenix metropolitan area . The Cardinals compete in the National Football League (NFL) as a member of the league's National Football Conference (NFC) West division . The Cardinals were founded as the Morgan Athletic Club in 1898, and are the oldest continuously run professional football team in the United States . The Cardinals play their home games at State Farm Stadium, which opened in 2006 and is located in the northwestern suburb of Glendale . </P> <P> The team was established in Chicago in 1898 as an amateur football team and joined the NFL as a charter member on September 17, 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 a year after its creation in 1921 .) The club then moved to St. Louis 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 St. Louis Cardinals of Major League Baseball). Before the 1988 season, the team moved west to Tempe, Arizona, a college suburb east of Phoenix, and played their home games for the next 18 seasons at Sun Devil Stadium on the campus of Arizona State University . In 2006, the club moved to their current home field in Glendale, although the team's executive offices and training facility remain in Tempe . </P> <P> The franchise has won two NFL championships, both while it was based in Chicago . The first occurred in 1925, but is the subject of controversy, with supporters of the Pottsville Maroons believing that Pottsville should have won the title . Their second title, and the first to be won in a championship game, came in 1947, nearly two decades before the first Super Bowl . They returned to the title game to defend in 1948, but lost the rematch 7--0 in a snowstorm in Philadelphia . </P>
