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.
Aquitaine, archaic Guyenne or Guienne, is a historical region of Southwestern France and a former administrative region. Since 1 January 2016 it has been part of the administrative region of Nouvelle-Aquitaine. It is situated in the southwest corner of metropolitan France, along the Atlantic Ocean and the Pyrenees mountain range on the border with Spain; for most of its written history Bordeaux has been a vital port and administrative centre. It is composed of the five departments of Dordogne, Lot-et-Garonne, Pyrénées-Atlantiques, Landes and Gironde. Gallia Aquitania was established by the Romans in ancient times and in the Middle Ages, Aquitaine was a kingdom and a duchy, whose boundaries fluctuated considerably.
Gascony was a province of the southwestern Kingdom of France that succeeded the Duchy of Gascony (602–1453). From the 17th century until the French Revolution (1789–1799), it was part of the combined Province of Guyenne and Gascony. The region is vaguely defined, and the distinction between Guyenne and Gascony is unclear; by some they are seen to overlap, while others consider Gascony a part of Guyenne. Most definitions put Gascony east and south of Bordeaux.
Gascon is the vernacular Romance variety spoken mainly in the region of Gascony, France. It is often considered a variety of Occitan, although some authors consider it a different language.
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.
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 Vascones were a pre-Roman tribe who, on the arrival of the Romans in the 1st century, inhabited a territory that spanned between the upper course of the Ebro river and the southern basin of the western Pyrenees, a region that coincides with present-day Navarre, western Aragon and northeastern La Rioja, in the Iberian Peninsula. The Vascones are often considered ancestors of the present-day Basques to whom they left their name.
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.
Bigorre is a region in southwest France, historically an independent county and later a French province, located in the upper watershed of the Adour, on the northern slopes of the Pyrenees, part of the larger region known as Gascony. Today Bigorre comprises the centre and west of the département of Hautes-Pyrénées, with two small exclaves in the neighbouring Pyrénées Atlantiques. Its inhabitants are called Bigourdans.
Couserans is a former county of France located in the Pyrenees mountains. Today Couserans makes up the western half of the Ariège département, around the towns of Saint-Girons and Saint-Lizier. A small part of Couserans is also in the extreme south of Haute-Garonne, just across the border from Ariège.
The Aquitanian language was the language of the ancient Aquitani, spoken on both sides of the western Pyrenees in ancient Aquitaine and in the areas south of the Pyrenees in the valleys of the Basque Country before the Roman conquest. It probably survived in Aquitania north of the Pyrenees until the Early Middle Ages.
The Duchy of Gascony or Duchy of Vasconia was a duchy located in present-day southwestern France and northeastern Spain, an area encompassing the modern region of Gascony. The Duchy of Gascony, then known as Wasconia, was originally a Frankish march formed to hold sway over the Basques. However, the duchy went through different periods, from its early years with its distinctively Basque element to the merger in personal union with the Duchy of Aquitaine to the later period as a dependency of the Plantagenet kings of England.
Novempopulania was one of the provinces created by Diocletian out of Gallia Aquitania, which was also called Aquitania Tertia.
The Tarbelli were an Aquitani tribe dwelling in the present-day regions of Labourd and Chalosse, in the west of Aquitania, during the Iron Age.
The Cocosates or Cocosates Sexsignani were an Aquitani tribe dwelling in present-day Landes during the Iron Age.
Gallia Celtica, meaning "Celtic Gaul" in Latin, was a cultural region of Gaul inhabited by Celts, located in what is now France, Switzerland, Luxembourg and the west bank of the Rhine River in Germany.
The Sotiates were a Gallic-Aquitani tribe dwelling in the region surrounding the modern town of Sos (Lot-et-Garonne) during the Iron Age and the Roman period.
The Auscii or Ausci were an Aquitani tribe dwelling around present-day Auch during the Iron Age.
The Bigerriones or Begerri were an Aquitani tribe dwelling in present-day Bigorre during the Iron Age.
