French language
In ancient times, the Celts lived in what is now France. In those days, the land was called Gaul (Latin: Gallia).  The Romans conquered Gallia and divided it into provinces. Because the Romans spoke Latin, the local people learned Latin and began to speak it. Their own language, Gaulish, tended to be spoken less often, although Breton is a language still spoken today in the part of France called Brittany, that came from the old Celtic language.
