Final answer:
The stabilization of American Indian settlements led to intensified relations and conflicts between Native American tribes and American settlers, creating an atmosphere of disagreement and often violence as settlers moved westward, resulting in government interventions and policy changes.
Step-by-step explanation:
With stabilization of the American Indian settlements, relations between the two races became more and more intense. This intensity created a conflictual relationship that had profound effects on Native tribes and their cultures.
As American settlers encroached on Native American land, the need for government intervention increased. The settlers viewed the Native tribes as an obstacle to expansion, which was considered vital to the nation's interests.
Consequently, the 'Indian problem' arose in the American West, leading to a series of violent confrontations known as the Indian Wars. Despite some Native victories, the outcome was invariably the structural transformation of tribal cultures and the forced relocation of tribes onto reservations.
Interracial relationships were also a part of this tumultuous period. The blending of Native Americans, Europeans, and Africans underscored the radical differences that existed between these groups, affecting their ability to come together.
Additionally, the Washington administration's policies toward Native Americans highlighted the tensions as white citizens and government officials saw them as impediments to white settlement, further exacerbating conflicts and leading to devastating outcomes for Native tribes.
