Gaius Julius Caesar remains one of the most studied characters of antiquity. His personality, political career, and military campaigns have garnered numerous scholarly treatments, as have his alleged aspirations to monarchy and divinity. However, comparatively little detailed work has been done to examine his own personal religiosity and even less attention has been paid to his religion in the context of his military conquests. I argue that Caesar has wrongly been deemed irreligious or skeptical and that his conduct while on campaign demonstrates that he was a religious man. Within the Roman system of religion, ritual participation was more important than faith or belief. Caesar pragmatically manipulated the Romans' flexible religious framework to secure military advantage almost entirely within the accepted bounds of religious conduct. If strict observance of ritual was the measure of Roman religiosity, then Caesar exceeded the religious expectations of his rank and office. The evidence reveals that he was an exemplar of Roman religio throughout both the Gallic Wars (58-51BC) and the subsequent Civil Wars (49-45BC).
