 The physical arrangement of the amphitheatre represented the order of Roman society: the emperor presiding in his opulent box; senators and equestrians watching from the advantageous seats reserved for them; women seated at a remove from the action; slaves given the worst places, and everybody else packed in-between. The crowd could call for an outcome by booing or cheering, but the emperor had the final say. Spectacles could quickly become sites of social and political protest, and emperors sometimes had to deploy force to put down crowd unrest, most notoriously at the Nika riots in the year 532, when troops under Justinian slaughtered thousands.
