700 BCE - 1497 CE - Long before European contact, North America was home to vibrant civilisations. From the Ancestral Puebloans, Hohokam, and Mogollon in the Southwest to the Adena, Hopewell, and Mississippian cultures of the Eastern Woodlands, these societies thrived. In the Arctic, the Dorset and Thule peoples adapted to the harsh northern climate, leaving behind remarkable legacies.
