While initially aimed at fostering relationships with Native tribes through diplomacy during the expedition, increased interest in westward expansion led to policies that often disregarded tribal sovereignty. As settlers moved westward, treaties were frequently broken or ignored, resulting in displacement and conflict. This cycle of exploration followed by colonization contributed to systemic changes that profoundly affected Native American communities across the continent.
