Why is San Francisco's football team called the 49ers?

Answer 1

• The "49ers" was the nickname given to the gold miners in California. They received that nickname because of the year that gold was discovered at Sutter's mill which began the gold rush.
• The team was named after the age of the actual 49'ers, citizens of the USA who flocked out West in the years surrounding 1849 to prospect for gold. The transient homesteaders were often referred to as 49'ers and helped build the West. As they came and stayed, railroads were built, cities went up and the West became the new frontier.
