After the conquest of Gaul by Julius Caesar, Tolosa did not participate in the uprisings against Rome during the Gallic wars and southern France would be the most Romanized part of France after the decline of the Roman Empire. Caesar established his camp on the Tolosa plain in 52 BC, conquering western Aquitania. With the conquest of Aquitania and Gaul, Tolosa was no longer a military outpost. Capitalizing on its position for trade between the Mediterranean and the Atlantic (both now under Roman control), the city grew rapidly.
