What might be considered a primary driver for the desire to expand westward in the U.S.?

The desire to expand westward in the U.S. was largely driven by the search for resources and gold, particularly during the 19th century. This period, famously known as the Gold Rush, saw thousands of people migrate westward in hopes of striking it rich after gold was discovered in California in 1848. The allure of gold was not just about wealth; it was also connected to the promise of new opportunities and the chance to build a prosperous life in previously unoccupied territories.

Additionally, westward expansion was encouraged by the belief in Manifest Destiny, the idea that Americans were divinely ordained to expand across the continent. This mindset propelled efforts to access and exploit the vast natural resources available in the western lands, such as fertile farmland, timber, and minerals. Therefore, the pursuit of resources, especially gold, was a central motivating force behind this westward movement, aligning with a broader economic goal of growth and prosperity for the nation.
