The San Francisco 49ers are called the "49ers" as a tribute to the prospectors who flocked to Northern California in 1849 during the California Gold Rush. These fortune seekers, known as "forty-niners," played a significant role in California's history by accelerating its economic growth and statehood. When the football team was founded in 1946, the name "49ers" was chosen to honor this era of adventurous gold miners. The team's colors, red and gold, also pay homage to the gold rush theme, and their mascot, Sourdough Sam, represents a gold prospector from that time.
