It is 113 BC Rome is a Republic, a small empire that clings to the rim of the Mediterranean. Though a democracy in name and spirit, a man must be rich and from the noble class to hold the highest offices, both political and military. The system has worked well for three centuries. But now a barbarian horde known as the Cimbri smashes through the northern imperial border. One humiliating defeat follows another, with losses of hundreds of thousands of Roman legionaries. Terror grips Rome and drives her into the arms of General Marius. Though he is a commoner, he has a brilliant military mind. To defeat the Cimbri, Marius will transform the Roman army and shake the Republic's political foundations to the core. It is a turning point for the Republic. Faced with the savage Cimbri, Rome must decide between dictatorship or annihilation.
