The main reason for the rise in expansion in the U.S. was the pursuit of economic opportunities, driven by factors such as the availability of land, the promise of wealth through agriculture and resources, and the desire for new markets. Additionally, technological advancements in transportation, such as the railroad, facilitated movement and settlement in new territories. This expansion was also fueled by a belief in Manifest Destiny, the idea that Americans were destined to spread across the continent.
