When did the New England Patriots win their first Super Bowl?
The New England Patriots won their first Super Bowl under coach Bill Belichick in February 2002. In 1986 the franchise went to their first Super Bowl, but the Chicago Bears decimated them by a score of 46-10. In 1997 the Patriots went back to the Super Bowl, but were defeated by Brett Favre and the Green Bay Packers by a score of 35-21. And in 2004, the franchise established itself as a legitimate dynasty in the eyes of many pundits by winning its third Super Bowl in four years against the Philadelphia Eagles. Source nfl.com
