American Indian history encompasses the diverse experiences and cultures of the indigenous peoples of North America. Before European contact, various tribes, such as the Navajo, Sioux, and Iroquois, developed rich traditions, languages, and social structures. Their ways of life were deeply connected to the land and its resources. The arrival of Europeans in the 15th century led to significant changes, including colonization, displacement, and conflict. Treaties were often made and broken, resulting in loss of land and sovereignty for many tribes. Despite these challenges, American Indian communities continue to preserve their cultures and advocate for their rights today.
