Cambria - Latin name of Wales

"Cambria is a name for Wales, being the Latinised form of the Welsh name for the country, Cymru. The term was not in use during the Roman period. It emerged later, in the medieval period, after the Anglo-Saxon settlement of much of Britain led to a territorial distinction between the new Anglo-Saxon kingdoms and the remaining Celtic British kingdoms. Latin being the primary language of scholarship in Western Christendom, writers needed a term to refer to the Celtic British territory and coined Cambria based on the Welsh name for it. - Wikipedia"
