The document summarizes the main tribes that lived in Hispania (Roman Spain) during Roman times: the Tartars in the southwest, the Iberians in the east and south, and the Celtics in the center, west, and north. The Tartars developed in the first half of the first millennium BC and had a rich civilization that collapsed in the mid-first millennium. The Iberians settled in towns and had an agricultural economy and hierarchical society governed by chieftains, with refined art. The Celtics' economy also involved agriculture and livestock, and their polytheistic religion involved Druids and mythological creatures.
