The Pittsburgh Steelers are a professional American football team based in Pittsburgh. The Steelers compete in the National Football League (NFL) as a member of the American Football Conference (AFC) North division. Founded in 1933, the Steelers are the seventh-oldest franchise in the NFL, and the oldest franchise in the AFC.
In contrast with their status as a perennial losing franchise in the pre-merger NFL, where they were the oldest team never to have won a league championship, the Steelers of the post-merger (modern) era are among the most successful NFL franchises, especially during their dynasty in the 1970s.
