The native peoples of America were a diverse set of indigenous peoples with unique cultures, dialects, and traditions on the eve of European arrival on the coasts of the Western Hemisphere. They lived in a variety of communities, from hunter-gatherers to agrarian, with complex social and political structures. They were proficient in a variety of skills, including weaving, ceramics, and metalworking, and they had a strong spiritual connection to the land and nature. Their numbers throughout North, Central, and South America were thought to be in the millions.
