Where Was Ancient Gaul Located?

Gaul (Latin: Gallia) was the Roman designation for the Celtic-inhabited region of Western Europe roughly corresponding to:

• Modern France (entirety)
• Belgium (all)
• Western Germany west of the Rhine (Rhineland, Palatinate, Saarland)
• Northern Italy — Gallia Cisalpina (Po Valley, south of Alps)
• Switzerland (western & northern parts)
• Netherlands (southern, below Rhine)

Roman Administrative Divisions (after Caesar, 50s BCE)

• Gallia Cisalpina — N. Italy (incorporated into Italy 42 BCE)
• Gallia Narbonensis — Mediterranean coast (Provence, Languedoc); colonized 121 BCE
• Gallia Comata ("Long-haired Gaul") — rest of France/Belgium, divided by Augustus into:
• — Aquitania (SW France)
• — Lugdunensis (NW/Central France; capital Lugdunum = Lyon)
• — Belgica (N. France, Belgium, W. Germany; capital Durocortorum = Reims)

People & Culture

Celtic tribes (Arverni, Aedui, Sequani, Belgae, Parisii, etc.) — ironworking, oppida (hillforts), druidic religion, coinage, trade with Mediterranean. Conquered by Caesar 58–50 BCE (Commentarii de Bello Gallico). Romanized rapidly: Latin, cities, roads, villas, citizenship (212 CE Caracalla edict).

Modern legacy: "France" derives from Franks (Germanic), but French language, law, and territory owe more to Roman Gaul.
