The Corieltauvi were a Celtic tribe living in Britain prior to the Roman conquest, and thereafter a civitas of Roman Britain. Their territory was in what is now the English East Midlands. They were bordered by the Brigantes to the north, the Cornovii to the west, the Dobunni and Catuvellauni to the south, and the Iceni to the east. Their capital was called Ratae Corieltauvorum, known today as Leicester.

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.
