Part 2/8:
Oakland's journey into the realm of major professional sports began in 1960 with the inception of the Oakland Raiders in the American Football League (AFL). The push for expansion into the West Coast by then Los Angeles Chargers owner Baron Hilton facilitated the Raiders' establishment. The team's initial instability, due to venue issues, was addressed when plans were secured for the construction of the Oakland Coliseum, opening in 1966 alongside the Coliseum Arena.
This period was a landmark for Oakland, transitioning from having no professional teams to hosting four major franchises in a short span:
The Oakland Raiders (NFL)
Oakland Athletics (MLB)
Golden State Warriors (NBA)
California Golden Seals (NHL)
