Famine in Rome is causing unrest between the common people and the patricians (the aristocrats of Rome). The people particularly resent the arrogant Caius Martius, son of Volumnia, who makes no secret of the fact that he despises them. The citizens rise up against the patricians, whom they suspect of hoarding corn for themselves. They are rewarded with the creation of two people’s representatives, or tribunes, who are given new powers to sit in the Senate. War with the neighbouring Volscians halts the rioting, however, and, in the battle for the town of Corioli, Caius Martius leads the Roman army with such spectacular bravery that he is honoured with the title ‘Coriolanus’.
