Gaul (Transalpine)(see map: The Roman empire (western provinces)) comprised the area from the Pyrenees and the Mediterranean coast of modern France to the English Channel, and the Atlantic to the Rhine and the western Alps. As a geopolitical entity, it emerged in the 1st cent. bc and lasted into the 5th cent. ad. Augustus divided Gaul into four provinces: Narbonensis, Lugdunensis, Aquitania, and Belgica.
