How did the Americans change the Native Americans lives This is for a test it is CRUCIAL?

The arrival of Americans significantly altered Native American lives through processes such as land dispossession, forced relocation, and cultural assimilation. Many Native tribes were pushed off their ancestral lands due to expansionist policies and treaties that were often broken. Additionally, the introduction of new goods, diseases, and lifestyles disrupted traditional ways of living, leading to significant changes in their social structures and economies. Ultimately, these changes resulted in lasting impacts on Native American communities, including loss of autonomy and cultural identity.
