The Patriots hold the records for most Super Bowl wins (6, tied with the Pittsburgh Steelers), appearances (11), and losses (5, tied with the Denver Broncos). Generally unsuccessful prior to the 21st century, the team enjoyed a period of dominance under head coach Bill Belichick and quarterback Tom Brady from 2001 to 2019. The Brady–Belichick era, regarded as one of sports' greatest dynasties, would see the Patriots claim nearly every major Super Bowl record.
