Gaul was a region of Western Europe first clearly described by the Romans, encompassing present-day France, Belgium, Luxembourg, and parts of Switzerland, the Netherlands, Germany, and Northern Italy. It covered an area of 494,000 km2 (191,000 sq mi). According to Julius Caesar, who took control of the region on behalf of the Roman Republic, Gaul was divided into three parts: Gallia Celtica, Belgica, and Aquitania.
Gallia Lugdunensis was a province of the Roman Empire in what is now the modern country of France, part of the Celtic territory of Gaul formerly known as Celtica. It is named after its capital Lugdunum, possibly Roman Europe's major city west of Italy, and a major imperial mint. Outside Lugdunum was the Sanctuary of the Three Gauls, where representatives met to celebrate the cult of Rome and Augustus.
In ancient times, Armorica or Aremorica was a region of Gaul between the Seine and the Loire that includes the Brittany Peninsula, extending inland to an indeterminate point and down the Atlantic Coast.
Gallia Aquitania, also known as Aquitaine or Aquitaine Gaul, was a province of the Roman Empire. It lies in present-day southwest France, where it gives its name to the modern region of Aquitaine. It was bordered by the provinces of Gallia Lugdunensis, Gallia Narbonensis, and Hispania Tarraconensis.
The Belgae were a large confederation of tribes living in northern Gaul, between the English Channel, the west bank of the Rhine, and the northern bank of the river Seine, from at least the third century BC. They were discussed in depth by Julius Caesar in his account of his wars in Gaul. Some peoples in southern Britain were also called Belgae and had apparently moved from the continent. T. F. O'Rahilly believed that some had moved further west and he equated them with the Fir Bolg in Ireland. The Roman province of Gallia Belgica was named after the continental Belgae. The term continued to be used in the region until the present day and is reflected in the name of the modern country of Belgium.
Gallia Belgica was a province of the Roman Empire located in the north-eastern part of Roman Gaul, in what is today primarily northern France, Belgium, and Luxembourg, along with parts of the Netherlands and Germany.
The Menapii were a Belgic tribe dwelling near the North Sea, around present-day Cassel, during the Iron Age and the Roman period.
The Lingones were a Gallic tribe of the Iron Age and Roman periods. They dwelled in the region surrounding the present-day city of Langres, between the provinces of Gallia Lugdunensis and Gallia Belgica.
The Volcae were a Gallic tribal confederation constituted before the raid of combined Gauls that invaded Macedonia c. 270 BC and fought the assembled Greeks at the Battle of Thermopylae in 279 BC. Tribes known by the name Volcae were found simultaneously in southern Gaul, Moravia, the Ebro valley of the Iberian Peninsula, and Galatia in Anatolia. The Volcae appear to have been part of the late La Tène material culture, and a Celtic identity has been attributed to the Volcae, based on mentions in Greek and Latin sources as well as onomastic evidence. Driven by highly mobile groups operating outside the tribal system and comprising diverse elements, the Volcae were one of the new ethnic entities formed during the Celtic military expansion at the beginning of the 3rd century BC. Collecting in the famous excursion into the Balkans, ostensibly, from the Greek point of view, to raid Delphi, a branch of the Volcae split from the main group on the way into the Balkans and joined two other tribes, the Tolistobogii and the Trocmi, to settle in central Anatolia and establish a new identity as the Galatians.
The Morini were a Belgic coastal tribe dwelling in the modern Pas de Calais region, around present-day Boulogne-sur-Mer, during the Iron Age and the Roman period.
The Aquitani were a tribe that lived in the region between the Pyrenees, the Atlantic ocean, and the Garonne, in present-day southwestern France in the 1st century BCE. The Romans dubbed this region Gallia Aquitania. Classical authors such as Julius Caesar and Strabo clearly distinguish the Aquitani from the other peoples of Gaul, and note their similarity to others in the Iberian Peninsula.
The Sequani were a Gallic tribe dwelling in the upper river basin of the Arar river (Saône), the valley of the Doubs and the Jura Mountains during the Iron Age and the Roman period.
Roman Gaul refers to Gaul under provincial rule in the Roman Empire from the 1st century BC to the 5th century AD.
The Pictones were a Gallic tribe dwelling south of the Loire river, in the modern departments of Vendée, Deux-Sèvres and Vienne, during the Iron Age and Roman period.
The Caletes or Caleti were a Belgic or Gallic tribe dwelling in Pays de Caux, in present-day Normandy, during the Iron Age and the Roman period.
The various names used since classical times for the people known today as the Celts are of disparate origins.
The Gauls were a group of Celtic peoples of mainland Europe in the Iron Age and the Roman period. Their homeland was known as Gaul (Gallia). They spoke Gaulish, a continental Celtic language.
The Sanctuary of the Three Gauls(Tres Galliae) (French: Sanctuaire fédéral des Trois Gaules) was the focal structure within an administrative and religious complex established by Rome in the very late 1st century BC at Lugdunum (the site of modern Lyon in France). Its institution served to federalise and develop Gallia Comata as an Imperial province under Augustus, following the Gallic Wars of his predecessor Julius Caesar. The distinctively Gallo-Roman development of the Imperial sanctuary and its surrounding complex are well attested by literary, epigraphic, numismatic and archaeological evidence.
Over the course of nearly four centuries, the Roman Republic fought a series of wars against various Celtic tribes, whom they collectively described as Galli, or Gauls. Among the principal Gallic peoples described as antagonists by Greek and Roman writers were the Senones, Insubres, Boii, and Gaesatae.
