The Seattle Seahawks are a National Football League team based in Seattle, Washington. They are currently members of the Western Division of the National Football Conference (NFC), and joined the NFL in 1976 as an expansion team along with the Tampa Bay Buccaneers. Seattle is the only team to have played in both the AFC (American Football Conference) and NFC Championship Games. The Seahawks' only Super Bowl appearance was in 2006 for Super Bowl XL where they were defeated by the Pittsburgh Steelers.

On June 15, 1972, Seattle Professional Football Inc., a group of Seattle business and community leaders, announced its intention to acquire an NFL franchise for the city of Seattle, WA. Around two years later on June 4, 1974, the NFL gave the city an expansion franchise. On December 5, 1974, NFL Commissioner Pete Rozelle announced the official signing of the franchise agreement by Lloyd W. Nordstrom, representing the Nordstrom family as majority partners for the consortium. Nordstrom died of a heart attack before the Seahawks played their first game.
