The San Francisco 49ers are a professional American football team based in San Francisco, California, playing in the West Division of the National Football Conference (NFC) in the National Football League (NFL). The team was founded in 1946 as a charter member of the All-America Football Conference (AAFC) and joined the NFL in 1949 after the two leagues merged. When owned by the DeBartolo / York families, the 49ers became known for having one of the NFL's greatest dynasties, winning five Super Bowl championships in just 14 years, between 1981 and 1994, with four of those championships in the 1980s. The Super Bowl teams were led by Hall of Famers Joe Montana, Jerry Rice, Ronnie Lott, Steve Young, and coach Bill Walsh. With five Super Bowl wins, the 49ers are tied with the Dallas Cowboys for the second-most Super Bowl wins.
