One-Page Summary
Book IV, usually associated with the “Revolution” of Rome, turns from conquest toward the breakdown of the republican system itself. The central problem is that Rome has become too powerful and socially unequal for the old political structures to function as they once did. Wealth from empire transforms the economy, large estates and slave labor reshape society, and military service increasingly connects soldiers to individual commanders rather than to the state as an abstract institution. Mommsen follows the political struggles surrounding the Gracchi, Marius, Sulla, and the violent conflicts that gradually make constitutional compromise harder.
What makes the period tragic is that many protagonists believe they are defending the Republic even while their methods weaken it. Reformers use extraordinary measures because ordinary politics seems incapable of solving urgent problems; opponents respond with equally extraordinary force. The result is a cycle in which each attempt to restore order produces another precedent for concentrating power. The “revolution” is therefore not one event. It is a long erosion of the habits that made republican government possible.
