Political map of Europe & the Mediterranean 30 April 47 AD (Roman Conquest of Britain): Following the capture of Camulodunon (43 AD), Claudius returned to the continent, leaving command in Britain (Roman conquest of Britain) to his general Aulus Plautius. Accepting the Iceni, Dobunni, and Brigantes as client states, Plautius consolidated the Roman hold in southern Britain by conquering the Catuvellauni heartland. Defeated, Caratacus, the last Catuvellauni king, fled to what is now Wales, where British tribes would continue to resist the invaders for several decades.
