How did conflict on the American front tier increased tensions between the US and?

Conflict on the American frontier, particularly during the westward expansion, heightened tensions between the United States and Native American tribes, as the U.S. government sought to assert control over territories traditionally inhabited by Indigenous peoples. Violent confrontations, treaties that were often broken, and forced removals, such as the Trail of Tears, exacerbated these tensions. Additionally, the desire for land and resources led to further conflicts with neighboring countries, like Britain and Spain, over territorial claims and trade routes. This complex interplay of expansion and resistance significantly shaped U.S. relations with Indigenous populations and foreign nations.
