Gaul was divided by Augustus into Roman provinces. Many cities were founded during the Gallo-Roman period, including Lugdunum (present-day Lyon), which is considered the capital of the Gauls. These cities were built in traditional Roman style, with a forum, a theatre, a circus, an amphitheatre and thermal baths. The Gauls mixed with Roman settlers and eventually adopted Roman culture and Roman speech (Latin, from which the French language evolved). The Roman polytheism merged with the Gallic paganism into the same syncretism.
