There had been some movements toward westward settlement in the 1840s, but that trend accelerated dramatically with the discovery of gold in California. James Marshall's finding of gold at Sutter's Mill in California in 1848 led to a "gold rush" in the decade that followed, with 1849 seeing a huge influx of people to California.
