The Ordovices were one of the Celtic tribes living in the British Islands, before the Roman invasion of Britain. Its tribal lands were located in Wales between the Silures to the south and the Deceangli to the north-east. The Ordovices were conquered by the Roman governor Gnaeus Julius Agricola in the campaign of AD 77/78.

Gnaeus Julius Agricola

The name Ordo-vic- probably means "those fighting with a hammer". Irish Ord "hammer", Welsh Gordd "hammer" (with a G- prothetic), Breton Horzh "hammer" (with a H- prothetic).

Hill Fort

The Ordovices were farmers and shepherds but had a strong military tradition and lived in fortified strongholds and hillforts. They were among the few British tribes that resisted the Roman invasion. The resistance was mainly organized by the Celtic leader Caratacus, exiled in their lands after the defeat of his tribe in the Battle of the Medway. Caratacus became the warlord of the Ordovices and neighbouring Silures, and a Roman public enemy in the decade of 50. Following the Battle of Caer Caradoc, where governor Publius Ostorius Scapula defeated Caratacus, the Ordovices stopped being a threat to Rome, probably due to heavy losses.

Caractacus before Claudius

In the 70s, the Ordovices rebelled against Roman occupation and destroyed a cavalry squadron. This act of war provoked an equally strong response by Agricola, who, according to Tacitus, exterminated the whole tribe. No other mention of the tribe appears in the historical records, but in view of the terrain of the area occupied by the Ordovices it is questionable whether Agricola could have wiped out the entire population. The name of this tribe appears to be preserved in the place name Dinorwig ("Fort of the Ordovices") in North Wales.
