Which country does Gaul belong to?

Gaul (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 once 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 present-day Spain.

Gaul is divided into three regions:

(1) Gaul in Shannan, or Inner Gaul, that is, the northern part of Italy between the southern Alps and the Rubicon River basin;

(2) Gaul in the north of the mountain, or outer Gaul, that is, the Alps pass through the northern shore of the Mediterranean and connect the vast area north of the Pyrenees, which is equivalent to France, Belgium, the Netherlands, Luxembourg, Switzerland and Germany (on the left bank of the Rhine). This area is also commonly called Gaul.

3) Nalpo Gaul.

Now this word is often used instead of France.
