Why were the above carried out against Indian tribes?

Answer 1

The actions carried out against Indian tribes were largely driven by a combination of expansionist policies, economic interests, and a desire to assimilate Native American populations into Euro-American culture. As settlers moved westward, the U.S. government sought to acquire tribal lands for agriculture, mining, and settlement, often through treaties that were frequently broken. Additionally, there was a prevailing belief in Manifest Destiny, which justified the displacement of Native Americans as a means of spreading civilization. These factors collectively led to the systemic marginalization and often violent removal of Indigenous peoples from their ancestral lands.
