The Pittsburgh Steelers are a professional American football team based in Pittsburgh, Pennsylvania. They are members of the Northern Division of the American Football Conference (AFC), in the National Football League (NFL).
The Steelers are the oldest and most championed franchise in the AFC. The team has appeared in six Super Bowls and is, along with the San Francisco 49ers and Dallas Cowboys, one of three teams to have won the Super Bowl five times. They have appeared in thirteen Conference Championship Games, and have hosted more conference championship games than any other NFL franchise. They are the only team in NFL playoff history to win a Super Bowl after being seeded sixth in the playoffs, winning three consecutive games on the road followed by a Super Bowl victory in Detroit on February 5, 2006 against the Seattle Seahawks.
Originally named the Pittsburgh Pirates, the team, along with the Philadelphia Eagles and the now-defunct Cincinnati Reds football team, joined the NFL as 1933 expansion teams, after Art Rooney, Sr. paid a $2,500 fee. However the Steelers are the heirs to the first ever pro-football team, Pittsburgh being the city to host the world's first pro game in the 1890's, a franchise that would still be in existence today if not for the strict state blue-laws preventing any activity during the Sabbath (NFL Sundays) up until 1933.
The team was renamed the Steelers in 1941 after the city's prominent steel industry to reflect the "blue-collar worker" ethic of the many Pittsburgh fans as well as to avoid confusion with the major league baseball team with the same name.
