The Philadelphia Eagles are a professional American football team based in Philadelphia. The Eagles compete in the National Football League (NFL) as a member club of the league's National Football Conference (NFC) East division. In the 2017 season the team won Super Bowl LII, their first Super Bowl win in franchise history and their fourth NFL title overall, after winning the Championship Game in 1948, 1949, and 1960. The franchise was established in 1933 as a replacement for the bankrupt Frankford Yellow Jackets, when a group led by Bert Bell secured the rights to an NFL franchise in Philadelphia. Bell, Chuck Bednarik, Bob Brown, Brian Dawkins, Reggie White, Steve Van Buren, Tommy McDonald, Greasy Neale, Pete Pihos, Harold Carmichael, Sonny Jurgensen, and Norm Van Brocklin have been inducted to the Pro Football Hall of Fame. The team has had an intense rivalry with the New York Giants. This rivalry is the oldest in the NFC East and is among the oldest in the NFL. It was ranked by NFL Network as the number one rivalry of all-time, Sports Illustrated ranks it as the fourth-best rivalry in the NFL, and according to ESPN, it is one of the fiercest and most well-known rivalries in the American football community. They also have a bitter rivalry with the Dallas Cowboys, which has become more high-profile since the 1960s, as well as a historic rivalry with the Washington Redskins. Their rivalry with the Pittsburgh Steelers is another bitter rivalry known as the battle of Pennsylvania, roughly dating back to 1933. It mostly arises from the two teams' statuses as being from opposite ends of the same state. The team consistently ranks among the best in the league in attendance and has sold out every game since the 1999 season. In a Sports Illustrated poll of 321 NFL players, Eagles fans were selected as the most intimidating fans in the NFL.
