Roman society was characterised by the client-patron relationship. The patron was a rich man who dispensed favours to his clients who were poor people or educated young men who had not yet made headway in their careers. The sort of favour the patron dispensed for the poor were cash hand-outs, errands and odd jobs. The favours for the educated young men were either employing their skilled services or helping to promote their careers. The clients, in their turn, were expected to give their patrons their loyalty and political support. Poor clients were often very dependent of their patron due to high levels of unemployment. Their livelihood depended on the favours of the patron.
