The Silures were a powerful and warlike tribe or tribal confederation of ancient Britain, occupying what is now south east Wales and perhaps some adjoining areas. They were bordered to the north by the Ordovices; to the east by the Dobunni; and to the west by the Demetae.

The British Iron Age is a conventional name used in the archaeology of Great Britain, referring to the prehistoric and protohistoric phases of the Iron Age culture of the main island and the smaller islands, typically excluding prehistoric Ireland, which had an independent Iron Age culture of its own. The Iron Age is not an archaeological horizon of common artefacts but is rather a locally-diverse cultural phase.
