What caused the Gallic Wars?
Regarding this, why did Julius Caesar write the Gallic Wars?
Since the Roman government disapproved of Caesar's undertakings, his literary aim in the Gallic War is to merely justify his actions of his annexation of Gaul (modern France) to Rome. To control a positive image in Rome, Caesar changes and conceals actual facts to make his actions appear just and necessary.
Subsequently, one may also ask, who won the Gallic Wars?
Rome's war against the Gallic tribes lasted from 58 BC to 50 BC and culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul (mainly present-day France and Belgium).
The Commentaries of Caesar on the Gallic War were known in Rome before the year 46 B.c.1 The enthusiastic praise of Cicero, so often quoted, was written then, but it indicates that the books had already been in circulation.
