The Arizona Cardinals are a professional American football team based in the Phoenix metropolitan area. They compete in the National Football League (NFL) as a member of the National Football Conference (NFC) West division, and play their home games at State Farm Stadium in Glendale, a suburb northwest of Phoenix. The Cardinals' history can be traced back to the 1898 formation of the amateur Morgan Athletic Club in Chicago. The team has won two NFL championships, in 1925 and 1947, and has made one Super Bowl appearance, in 2009, which they lost to the Pittsburgh Steelers. The Cardinals opened the state-of-the-art University of Phoenix Stadium in 2006, where they found instant success in their new home winning multiple division titles. The team's winningest coach is Bruce Arians, with a record of 49-30-1.
