The Belgae were a group of nations or tribes living in north-eastern Gaul, on the west bank of the Rhine, in the 1st century BC, and later also attested in Britain. Their name survives in modern Belgium. The name Belgae may come from the Proto-Celtic *belo which means "bright"and is allied to English word "bale" (as in "bale-fire"), the Anglo-Saxon "bael", the Lithuanian "baltas", meaning "white" or "shining" (from which the Baltic takes its name) and Slavic "belo/bilo/bjelo/..." meaning "white" (like town names Beograd, Biograd, Bjelovar, etc all meaning "white city") (See Beltane). Thus the Gaulish god-names "Belenos" (*Bright one) and "Belisama" (probably the same divinity, originally from *belo-nos = our shining one) may also come from the same source.
Julius Caesar in his De Bello Gallico divided the people of Gaul at the time of his conquests (58 - 51 BC) into three broad groups: the Aquitani, Galli (who in their own language were called Celtae) and Belgae, all of whom had their own customs and language. He noted that the Belgae, being furthest from the developed civilisation of Rome and closest to the Germanic people, were the bravest of all Gauls, because "merchants least frequently resort to them, and import those things which tend to effeminate the mind" (Commentarii_de_Bello_Gallico, I,1).
It is also said that the Belgae were descendants of Trebata, the legendary founder of Trier.
Tribes who belonged to the Belgae included the warlike and influential Bellovaci who took a leading role in the councils of the Belgae, the Suessiones with territories as well in Britannia, the warlike Nervii, the Atrebates, Ambiani, Morini, Menapii, Caleti, Veliocasses, Viromandui. The Remi were united with them as neighbors and allies, they reported to Caesar. Caesar says one tribe, the Atuatuci, were descended from the Germanic Cimbri and Teutones, and describes four other allied tribes, the Condrusi, Eburones, Caerosi and Paemani, as Germanic tribes (although Ambiorix, a later leader of the Eburones, has a Celtic name). Other tribes that may have been included among the Belgae were the Leuci, Treveri, Tungri and Mediomatrici. Posidonius includes the Armoricani in Brittany as well.
The Belgae attacked over the river, but were repulsed after a fierce battle. Realising they could not dislodge the Romans and aware of the approach of the Aedui to the lands of the Bellovaci, the Belgae decided to disband their combined force and return to their own lands. Whichever tribe Caesar attacked first, the others would come to its defence. They broke camp shortly before midnight. At daybreak, satisfied the retreat was not a trap, Caesar sent cavalry to harass the rearguard, followed by three legions, and many of the Belgae were killed.
Caesar next marched into the territory of the Suessiones and besieged the town of Noviodunum (Soissons). Seeing the Romans' siege engines, the Suessiones surrendered, and Caesar turned his attention to the Bellovaci, who had retreated into the fortress of Bratuspantium (between modern Amiens and Beauvais). They quickly surrendered, as did the Ambiani.
The Nervii, along with the Atrebates and Viromandui, decided to fight (the Atuatuci had also agreed to join them but had not yet arrived). They concealed themselves in the forests and attacked the approaching Roman column at the river Sambre. Their attack was so quick and unexpected that some of the Romans didn't have time to take the covers off their shields or even put on their helmets. The element of surprise briefly left the Romans exposed. However Caesar grabbed a shield, made his way to the front line, and quickly organised his forces. The two legions who had been guarding the baggage train at the rear arrived and helped to turn the tide of the battle. Caesar says the Nervii were almost anihilated in the battle, and it is effusive in his tribute to their bravery, calling them "heroes".
The Atuatuci, who were marching to their aid, turned back on hearing of the defeat and retreated to one stronghold, were put under siege, and soon surrendered and handed over their arms. However the surrender was a ploy, and the Atuatuci, armed with weapons they had hidden, tried to break out during the night. The Romans had the advantage of position and killed four thousand. The rest, about fifty-three thousand, were sold into slavery.
In 53 BC the Eburones, led by Ambiorix, along with the Nervii, Menapii and Morini, revolted again and wiped out 15 cohorts, only to be put down by Caesar. The Belgae fought in the uprising of Vercingetorix in 52 BC.
After their final subjugation, Caesar combined the three parts of Gaul, the territory of the Belgae, Celtae and Aquitani, into a single unwieldy province (Gallia Comata, "long-haired Gaul") that was reorganized by Augustus Caesar into its traditional cultural divisions. The province of Gallia Belgica was bounded on its east by the Rhine and extended all the way from the North Sea to Lake Constance (Lacus Brigantinus), including parts of what is now western Switzerland, with its capital at the city of the Remi (Reims). Under Diocletian, Belgica Prima (capital, Augusta Trevirorum, Trier) and Belgica Secunda (capital Reims) formed part of the diocese of Gaul.
A large number of coins of the Ambiani dating to the mid-2nd century BC have been found in southern Britain, and within memory of Caesar's time a king of the Suessiones called Diviciacus was not only the most powerful king of Belgic Gaul but also ruled territory in Britain. Commius of the Atrebates, Caesar's former ally, fled to Britain after participating in Vercingetorix's rebellion and either joined or established a British branch of his tribe. Based on the development of imagery on coins, it seems likely that, by the time of the Roman conquest, most of the tribes of south-eastern Britain were Belgic or at least ruled by a Belgic aristocracy.
The later civitates (administrative divisions) of Roman Britain included one bearing the name of the Belgae, whose towns included Magnus Portus (Portsmouth) and Venta Belgarum (Winchester).
It is possible that a branch of the Belgae also settled in Ireland, represented by the historical Builg and the mythological Fir Bolg.
