This practice of emancipation – or manumission, to follow the Latin term – was such a distinctive feature of Roman culture that outsiders at the time remarked upon it and saw it as a powerful factor in Rome’s success. As one king of Macedon observed in the third century BCE, it was in this way that ‘the Romans have enlarged their country’. The scale was so great that some historians reckon that, by the second century CE, the majority of the free citizen population of the city of Rome had slaves somewhere in their ancestry.
