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.

Tribes of Wales at the time of the Roman invasion. Exact boundaries are conjectural.
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).
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.
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.
The
Ordovician geologic period was first described by
Charles Lapworth in
1879 based on rocks located in the original lands of the Ordovices and was named after them.
