How did the ancient Roman Republic end up with an empire? Was it merely a result of their defensive measures aimed at protecting themselves? Was it an offensive plan to conquer the Mediterranean World? Or was it simply inevitable given the nature of the Roman political and military system? Arguments have been made for all of these positions, and more, over the course of the twentieth century, and continuing into the twenty-first century.
