Gaul (Latin Gallia, French Gaule) is the name given by the Romans to the territories where the Celtic Gauls (Latin Galli, French Gaulois) lived, including present France, Belgium, Luxemburg and parts of the Netherlands, Switzerland, Germany on the west bank of the Rhine, and the Po Valley, in present Italy.
As early as 1000 BC much of this fertile land now called France was occupied by the Celtic Gauls. The powerful Romans arrived, defeated the Gauls by 52 BC, and subsequently Rome ruled for almost 500 years. As the Roman Empire faded, France was overrun by a series of barbarian invaders and shattered into varied factions.
