Origin

Old English Breoton, from Latin Brittones Britons, superseded in Middle English by forms from Old French Bretaigne (from Latin Brit(t)annia). It became a largely historical term until revived in the mid 16th century, as the possible union of England and Scotland became a subject of political concern.
