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. The Belgae gave their name to the Roman province of Gallia Belgica and, much later, to the modern country of Belgium; today "Belgae" is also Latin for "Belgians".
- All Gaul is divided into three parts, one of which the Belgae inhabit, the Aquitani another, those who in their own language are called “Celts,” in our language “Gauls,” the third. All these differ from each other in language, customs and laws. The river Garonne separates the Gauls from the Aquitani; the Marne and the Seine separate them from the Belgae. Of all these, the Belgae are the bravest, because they are furthest from the civilization and refinement of [our] Province, and merchants least frequently resort to them, and import those things which tend to effeminate the mind; and they are the nearest to the Germans, who dwell beyond the Rhine, with whom they are continually waging war; for which reason the Helvetii also surpass the rest of the Gauls in valor, as they contend with the Germans in almost daily battles, when they either repel them from their own territories, or themselves wage war on their frontiers.

- They did not allow traders to come amongst them; they permitted no wine or any other luxuries to be imported, because they believed that these weakened the spirit and reduced courage.

- The whole race which is now called both Gallic and Galatic is war-mad... Although not otherwise simple... And therefore, if roused, they come together all at once for the struggle, both openly and without circumspection, so that for those who wish to defeat them by stratagem they become easy to deal with.

- When Caesar inquired of them what states were in arms, how powerful they were, and what they could do, in war, he received the following information: that the greater part of the Belgae were sprung, from the Germans, and that having crossed the Rhine at an early period, they had settled there, on account of the fertility of the country, and had driven out the Gauls who inhabited those regions; and that they were the only people who, in the memory of our fathers [i.e. as far as we can remember], when all Gaul was overrun, had prevented the Teutones and the Cimbri from entering their territories; the effect of which was, that, from the recollection of those events, they assumed to themselves great authority and haughtiness in military matters.

- Driven off from all parts; the corn not only was being consumed by so great numbers of cattle and men, but also had fallen to the earth, owing to the time of the year and the storms; so that if any had concealed themselves for the present, still, it appeared likely that they must perish through want of all things, when the army should be drawn off. And frequently it came to that point, as so large a body of cavalry had been sent abroad in all directions, that the prisoners declared Ambiorix had just then been seen by them in flight, […] but he rescued himself by [means of] lurking-places and forests, and, concealed by the night made for other districts and quarters, with no greater guard than that of four horsemen, to whom along he ventured to confide his life.
