Military Power
The Roman military, like the legal administration, changed over time. As Rome first rose into the state of being an Empire, their military was made up of farmers and normal citizens, whose incentive to fight for their Empire was a payment which was only made through conquest. As the Empire progressed, and Rome was able to acquire more land and people, the military advanced to be more professional. Towards the end of the representative republic, the military consisted of still mostly commoners, though some full-time soldiers started to be employed. Once the Empire fully switched to be imperialistic, the military also switched to be made up of almost all full-time soldiers. The Roman military expanded its variety as it got more professional. Being based around the Mediterranean Sea, Rome created a very powerful navy, along with its original infantry. Though the navy worked separately from the army, it was seen to be an extension of the original foot-soldiers, which not only ensured a greater cooperation of the soldiers, but also unified the army as a whole and enabled them to fight on two different grounds while still being able to work towards the same goal
