Bibroci

54 BCE – 54 BCE (approx.)

British people named only once by Julius Caesar, among the groups that surrendered to him during his second invasion in 54 BCE.

Origins

Known only from Caesar's Gallic War, the Bibroci were one of five British peoples, with the Cenimagni, Segontiaci, Ancalites and Cassi, who sent envoys to surrender to him in 54 BCE after the Trinovantes had come under his protection.

Rule and society

Nothing is recorded of their government, rulers or way of life. Their territory is unknown; scholars have suggested places in the Thames valley or in Berkshire and Sussex, but no inscription or coin securely names them.

Decline and legacy

They vanish from the record after Caesar's account. Their land was presumably absorbed by larger neighbours such as the Atrebates (Britain) or the Catuvellauni before the Roman conquest of 43.

Few sources survive for this state; details are uncertain.
