O n what direction did the united states expand?

The United States expanded predominantly westward across North America, driven by the belief in Manifest Destiny. This expansion included the acquisition of territories through treaties, purchases, and conflicts, such as the Louisiana Purchase, the annexation of Texas, and the Oregon Trail. The movement also extended southward and northward, influencing territories in present-day Mexico and Canada. Ultimately, this westward expansion shaped the nation's borders and its development as a continental power.
