When you hear the word Gaul (pronounced gol) you can think France, for it was the name formerly used for that geographical area. A Frenchman is sometimes referred to as a Gaul. Before it was France, it was called Gallia by the Romans who with Caesar’s leadership, conquered the area. Caesar’s Gaul was populated mostly by the Celts. Back then, it held more territory than today’s France. Gaul encompassed Belgium, some of Germany, Switzerland and Holland. Northern Italy was included too, it was considered Gallia Cisalpina.
The Gaels, on the other hand, (pronounced gales) are the Gaelic branch of the Celts, particularly those that wound up in the Scottish Highlands. The Gaelic word for it is Gaidheal (also pronounced gale). To go back in time further, before Gael it was Goidel. The Goidels were a round-headed Alpine people who mixed with the darker-skinned, long-headed people who became the Celts.
