The Pittsburgh Steelers are a professional American football team based in Pittsburgh, Pennsylvania. The Steelers compete in the National Football League (NFL), as a member club of the league's American Football Conference (AFC) North division. Founded in 1933, the Steelers are the oldest franchise in the AFC.
In contrast with their status as perennial also-rans in the pre-merger NFL, where they were the oldest team never to win a league championship, the Steelers of the post-merger (modern) era are one of the most successful NFL franchises. Pittsburgh has won more Super Bowl titles (6) and both played in (16) and hosted more conference championship games (11) than any other NFL team. The Steelers have won 8 AFC championships, tied with the Denver Broncos, but behind the New England Patriots' record 10 AFC championships. The Steelers share the record for second most Super Bowl appearances with the Broncos, and Dallas Cowboys (8). The Steelers lost their most recent championship appearance, Super Bowl XLV, on February 6, 2011.
The Steelers, whose history traces to a regional pro team that was established in the early 1920s, joined the NFL as the Pittsburgh Pirates on July 8, 1933, owned by Art Rooney and taking its original name from the baseball team of the same name, as was common practice for NFL teams at the time. To distinguish them from the baseball team, local media took to calling the football team the Rooneymen, an unofficial nickname which persisted for decades after the team adopted its current nickname. The ownership of the Steelers has remained within the Rooney family since its founding. Art's son, Dan Rooney owned the team from 1988 until his death in 2017. Much control of the franchise has been given to Dan's son Art Rooney II. The Steelers enjoy a large, widespread fanbase nicknamed Steeler Nation. The Steelers currently play their home games at Heinz Field on Pittsburgh's North Side in the North Shore neighborhood, which also hosts the University of Pittsburgh Panthers. Built in 2001, the stadium replaced Three Rivers Stadium which hosted the Steelers for 31 seasons. Prior to Three Rivers, the Steelers had played their games in Pitt Stadium and Forbes Field.
