Early trading kingdom at the mouth of the Guadalquivir Valley in southwestern Spain, site of a semi-mythical city referred to by ancient writers as a source of gold, silver, tin, and lead. Tartessos, in fact, was the late Bronze Age society that included the mines of the Río Tinto in its territory. There is strong circumstantial evidence in the Huelva hoard, for trading with Sardinia, Sicily, Cyprus, the Phoenicians, France, Brittany, and Ireland c 800-550 BC. It has given its name to the Tartessian culture of the early 1st millennium BC which is essentially Phoenician with Etruscan and Greek admixture and whose influence in Spain, on the civilized Iberians of the east coast and the less advanced peoples of the center and north, was considerable.
