The California event, commencing in 1848, involved a large-scale and rapid movement of people to a specific location following the discovery of a precious mineral. This period is frequently studied within the context of United States history courses, particularly Advanced Placement United States History. An example illustrating this phenomenon is the massive influx of prospectors and settlers into California following James W. Marshall’s discovery at Sutter’s Mill.

The increased population fueled rapid urbanization and infrastructure development, while also exacerbating tensions with indigenous populations and contributing to debates over slavery and statehood. Understanding this period provides crucial context for analyzing westward expansion, manifest destiny, and the lead-up to the Civil War.
