The Pacific Coast played a central role in the California Gold Rush by serving as a hub for trade, travel, labor, and expansion.

During the California Gold Rush (1848-1855), the Pacific Coast was integral in facilitating trade and travel, acting as the main entry point for thousands of prospectors and settlers. Cities like San Francisco became bustling ports for those traveling to the goldfields. Additionally, the coast provided essential labor for mining operations, with many workers arriving from various regions. The Gold Rush also fueled westward expansion, as settlers moved to California, leading to rapid growth and the establishment of new towns and infrastructure across the region.
