Hmm, there were several triggering events that promoted westward expansion of the United States. Victory in war over Mexico (1848) gave the US new lands in the west. A treaty with Britain (also in 1848) gave the US sole possession of some formerly disputed Oregon territory lands also. Plus, in 1848, gold was discovered in California (land newly in US possession after that Mexican war treaty), so that prodded westward expansion too.
