Octavian was left to decide where in Italy to settle the tens of thousands of veterans of the Macedonian campaign, whom the triumvirs had promised to discharge. The tens of thousands who had fought on the republican side with Brutus and Cassius could easily ally with a political opponent of Octavian if not appeased, and they also required land. There was no more government-controlled land to allot as settlements for their soldiers, so Octavian had to choose one of two options: alienating many Roman citizens by confiscating their land, or alienating many Roman soldiers who could mount a considerable opposition against him in the Roman heartland. Octavian chose the former. There were as many as eighteen Roman towns affected by the new settlements, with entire populations driven out or at least given partial evictions.
