The Arizona Cardinals are a professional American football team based in the Phoenix metropolitan area. The Cardinals 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 team was established in Chicago in 1898 as the Morgan Athletic Club, and joined the NFL as a charter member on September 17, 1920. The team moved to St. Louis in 1960 and played there until 1987. Before the 1988 season, the Arizona Cardinals moved west to Tempe, Arizona and played their home games for the next 18 seasons at Sun Devil Stadium on the campus of Arizona State University. In 2006, the team moved to their current home field in suburban Glendale, although their executive offices and training facility remain in Tempe. The Cardinals have won two NFL championships (in 1925 and 1947), both while the team were in Chicago. Since winning the championship in 1947, the team suffered many losing seasons, and currently holds the longest active championship drought of North American sports at 75 consecutive seasons. The team has also won five division titles since their 1947–48 NFL championship game appearances. The Arizona Cardinals have a total of 6 playoff appearances, 3 division titles and the one NFC championship since relocating to the Valley of the Sun in 1988.
