The Belgae (/ˈbɛldʒiː, ˈbɛlɡaɪ/) 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 Britain were also called Belgae and O'Rahilly equated them with the Fir Bolg in Ireland. 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".
