[History] How was order kept in Hellenistic societies?

[QuintusSertorius]

After some more reading, it would appear for scenario two the Friend would go first to the deuteroi class in Macedonia, then probably hire mercs to fill any shortfall in what he required. Could citizen-levies be raised in Macedonia?

For scenario three it would depend on where it was taking place. In Hellas or Ionia might there be courts with citizen-juries who could give judgement? Then in most other places the local satrap would perform the same role. Not sure about sentences, though.

On a more general point, what's a good read on Hellenistic society? Someone mentioned Peter Green's The Hellenistic Age in another thread, is it any good?
