The Detroit Lions are a National Football League team based in Detroit, Michigan. The Lions compete in the National Football Conference (NFC) North division. The team plays its home games at Ford Field in downtown Detroit. The Lions were established as an NFL team in 1930 in Portsmouth, Ohio (as the Spartans) before moving to Detroit for the 1934 season. They won four NFL championships prior to the 1970 merger with the AFL, but have not won any since 1957 and have never competed in the Super Bowl.
