The Roman conquest of Wales began in AD 48 and was completed in 78, with Roman rule lasting until 383. Roman rule in Wales was a military occupation, save for the southern coastal region of South Wales east of the Gower Peninsula, where there is a legacy of Romanisation. The only town in Wales founded by the Romans, Caerwent, is located in South Wales. Both Caerwent and Carmarthen, also in southern Wales, would become Roman "civitates". During the occupation both the region that would become Wales and its people were a mostly autonomous part of Roman Britain.
