What did the term "Concentration Camps" refer to during this era in relation to Native Americans?

The term "Concentration Camps" during this era in relation to Native Americans referred to areas where tribes were forcibly relocated and confined to specific regions. The U.S. government's policies in the 19th century, particularly during westward expansion, often involved the removal of Native American tribes from their ancestral lands. This was part of a broader effort to assimilate Native Americans into American society and make more land available for white settlers. These confined areas, sometimes referred to as reservations, were intended to control the Native population and limit their rights to their traditional territories. The use of "concentration" underscores the forced nature of these relocations, paralleling the term's usage in other historical contexts regarding confinement for control. This practice reflects the broader themes of displacement and oppression faced by Native Americans during this period of U.S. history, highlighting the government's role in subjugating indigenous populations for the benefit of expansionist policies.
