The Arizona Cardinals are a professional American Football team based in Glendale, Arizona. The Cardinals are members of the Western division of the National football conference in the NFL. The Cardinals were founded in 1898 and are the oldest continuously run professional American football club in the United States. The franchise’s lone NFL championship game victory came in 1947 while they were based in Chicago, and came two decades before the first Super Bowl game was ever played. The club’s other NFL championship occurred in 1925, eight years before the league began holding a championship game, and is a controversial title to this day. The mush contested title was believed to belong to the Pottsville Maroons but was given to the Cardinals instead in what is called the 1925 NFL Chapionship controversy. In the six plus decades since winning the championship in 1947, the Cardinals have qualified for the playoffs only six times and have won only won five playoff games. Three of which were achieved during their run in the 2008-09 NFL playoffs in which they reached Super Bowl XLIII.
