Native Americans were the original inhabitants of North and South America, with some groups arriving over 40,000 years ago. There were hundreds of tribes across the Americas, each with their own distinct cultures, languages, religious beliefs, and housing/clothing styles adapted to the local environment. The arrival of European settlers devastated American Indian populations and ways of life through disease, conflict, and displacement from traditional lands. While most Native Americans now live off reservations, many tribes strive to preserve their cultural heritage.
