San Francisco 49ers (AAFC)

The San Francisco 49ers are a professional American football team located in the San Francisco Bay Area. They compete in the National Football League (NFL) as a member of the league's National Football Conference (NFC) West division. The team currently plays its home games at Levi's Stadium in Santa Clara, California, located 45 miles (72 km) southeast of San Francisco in the heart of Silicon Valley. Since 1988, the 49ers have been headquartered in Santa Clara.

The team was founded in 1946 as a charter member of the All-America Football Conference (AAFC) and joined the NFL in 1949 when the leagues merged. The 49ers were the first major league professional sports franchise based in San Francisco. The name "49ers" comes from the prospectors who arrived in Northern California in the 1849 Gold Rush. The team is legally and corporately registered as the San Francisco Forty Niners, Ltd. The team began play at Kezar Stadium in San Francisco before moving across town to Candlestick Park in 1970 and then to Levi's Stadium in Santa Clara in 2014.

1946-1950

The San Francisco 49ers, an original member of the new All-America Football Conference (AAFC), were the first major league professional sports franchise based in San Francisco, and one of the first major league professional sports teams based on the Pacific Coast. The team joined the Los Angeles Rams of the rival National Football League as the first "big four"-sport playing in the Western United States in 1946, eventually becoming part of the NFL themselves in 1950.
