Final answer:
The confinement to reservations and the effort to assimilate Native Americans into American society were the primary results of the Indian Wars, leading to a seismic shift in Native American life and culture.
Step-by-step explanation:
The Result of the Indian Wars for American Indians
The result of the Indian Wars that forever changed life for American Indians was their confinement to reservations. The various conflicts known as the Indian Wars, including the Plains Wars, were essentially clashes over territory and sovereignty between expanding American settlers and the Native American tribes. During these conflicts, the federal government devised strategies and policies to forcibly relocate Native American tribes from their ancestral lands to reservations, drastically changing their way of life.
Government policies aimed at assimilation of Native Americans into American society had profound impacts on tribal cultures. These policies included promoting individual land ownership, Christian worship, and education for children in the English language - all cornerstones of Americanization efforts that undermined traditional Native American cultural practices.
These actions, coupled with military interventions by the U.S. Army, led to the loss of autonomy and traditional lifestyle for many tribes. Settlers' encroachment significantly disrupted Native American societies, leading to longstanding dependencies on governmental support and a permanent change in their societal structures.
