The Miami Dolphins are a professional American football team based in the Miami metropolitan area. The Dolphins compete in the National Football League as a member of the league's American Football Conference East division. The club plays its home games at Hard Rock Stadium, located in the northern suburb of Miami Gardens, Florida. The Dolphins are the oldest professional sports team in Florida. Of the four AFC East teams, Miami is the only team in the division that was not a charter member of the American Football League. The Dolphins were founded by attorney-politician Joe Robbie and actor-comedian Danny Thomas. They began play in the AFL in 1966. The region had not had a professional football team since the days of the Miami Seahawks, who played in the All-America Football Conference in 1946, before becoming the first incarnation of the Baltimore Colts. For the first few years, the Dolphins' full-time training camp and practice facilities were at Saint Andrew's School, a private boys boarding prep school in Boca Raton. Miami joined the NFL as a result of the 1970 AFL–NFL merger. The team played in its first Super Bowl in Super Bowl VI, losing to the Dallas Cowboys, 24–3.
