In which region did Cartimandua surrender Caratacus to the Romans?

Cartimandua, the queen of the Brigantes tribe in what is now northern England, played a significant role during the Roman conquest of Britain. Caratacus was the leader of the Catuvellauni tribe and became a prominent figure in resisting Roman invasion. After facing defeat, Caratacus fled and sought refuge with Cartimandua. Her decision to surrender him to the Romans was pivotal, as it marked a significant moment in the Roman conquest of Britain, reinforcing Roman authority in the region.

The correct context for this event is Britain, known in Latin as Britannia. This adds to the historical significance of Cartimandua's actions, as it not only highlights tribal dynamics but also the complex interactions with Roman forces during their expansion. The other regions listed in the options do not pertain to the historical events involving Cartimandua and Caratacus, as these events specifically unfolded in Britain.
