Roman Expansion

Roman expansion seemed to develop ad hoc; had some imperial ambitions, they didn't have a clear plan of doing so, and no grand plan or scheme for taking over the world. It seemed to happen and grow naturally out of their desire for security; though some would say instances like Siege of Saguntum shows clear Roman abuse of secutrity for their imperial ambitions (wanted to wage war on Carthage, Saguntum was a good excuse).

Not a clearly defined bureaucratic procedure to deal with conquered territories, and no plan to pay for it. Having to figure out after the fact, how to we (1) fund and (2) logistically manage this expansionism.
 * leads to a growing bureaucracy
 * permanent foreign military garrisons very expensive (moving away from "buy your own gear and fight if you can, come home during the winter" to a professional, government sponsored service)
 * Rise of the Publicani  :
 * tax collectors, getting money from (1) conquered peoples and (2) those who leased land (primarily farmers) from the Roman govt.
