Is Gaul a region or a country?

Gaul (French: Gaule Latin: Gallia) refers to France, Belgium, northern Italy, southern Netherlands, western Switzerland and the west bank of the Rhine River in Germany. In English, the word Gaul (French: Gaulois) may also refer to the residents living in that area. But more often, the word refers to those who use Gaul (a branch of Celtic language family), which is widely distributed in Europe and even extended to central Anatolia in Roman times. Gallia is a Roman word for Gaul.

In ancient Rome, Gauls were widely distributed in Europe and divided into two ethnic groups. In addition to the Gauls living in France, some people lived in the plains of northern Italy, and some Gauls immigrated to Spain today.

In order to rule Rome, Vercingetorix (72-64 BC), the tribal leader of Gaul, led the Gaul uprising, which was defeated by Caesar, surrendered and sentenced to be hanged.
