Why were some Romans concerned by the changes that accompanied the expansion of Roman international power?

Answer 1

The expansion of Roman power via conquest of other peoples was a double edged sword for some of Rome's leaders. Rome's military conquests brought to Rome more wealth via taxation and tribute from Rome's new territories. It also increased Rome's supply of resources in farming, mining and other aspects of industry that Rome required. Conquest also brought in new slaves to support the Roman economy. In addition, some leaders of the conquered lands saw that allegiance to Rome protected them from other empires that posed a more severe threat then having Rome rule their lands. The down side of Rome's expansion meant that Roman government had a new area to rule and that placed a degree of complications for Rome. It also brought Rome into closer contact with powers like Carthage which posed a threat to Rome. It also meant that Rome's military forces had to be expanded and thus this cost money and training time. Internally, Rome's military now gave Roman generals such as Caesar, more power and influence in the government of Rome.
