The Seattle Seahawks are a professional American football team based in Seattle. The Seahawks compete in the National Football League (NFL) as a member club of the league’s National Football Conference (NFC) West, which they joined in 2002. The club entered the NFL as an expansion team in 1976. From 1977 to 2001, Seattle was assigned to the American Football Conference (AFC) West. They have played their home games at Lumen Field in Seattle’s SoDo neighborhood since 2002, having previously played home games in the Kingdome (1976–1999) and Husky Stadium (1994 and 2000–2001). The Seahawks are currently coached by Pete Carroll.
Seahawks fans have been referred to collectively as the “12th Man,” “12th Fan,” or “12s.” The team’s fans twice set the Guinness World Record for the loudest crowd noise at a sporting event within the span of a few months, first registering 136.6 decibels during a game against the San Francisco 49ers in September 2013, and later registering 137.6 dB during a Monday Night Football game against the New Orleans Saints that December. As the only NFL team based in the Pacific Northwest region of North America, the Seahawks attract support from the wider geographical area that includes some parts of the U.S. states of Alaska, Idaho, Montana, Oregon, and Utah, as well as the Canadian provinces of Alberta, British Columbia, and Saskatchewan.
The Seahawks have won 10 division titles and three conference championships, and are the only team to have played in both the AFC and NFC Championship Games. They have progressed to three Super Bowls, losing 21–10 to the Pittsburgh Steelers at Super Bowl XL, defeating the Denver Broncos 43–8 for their first championship at Super Bowl XLVIII, and losing 28–24 to the New England Patriots at Super Bowl XLIX. NFL players Kenny Easley, Walter Jones, Steve Hutchinson, Cortez Kennedy, and Steve Largent have been voted into the Pro Football Hall of Fame primarily or wholly for their accomplishments as Seahawks. In addition, players Dave Brown, Jacob Green, Dave Krieg, Curt Warner, Jim Zorn, and Matt Hasselbeck have been inducted into the Seahawks Ring of Honor along with head coaches Chuck Knox and Mike Holmgren, radio announcer Pete Gross, and franchise owner Paul Allen.
