The Grand Strategy of the Roman Empire
From the First Century CE to the Third, Revised and Updated Edition

At the height of its power, the Roman Empire encompassed the entire Mediterranean basin. Rome prospered for centuries while successfully resisting attack, fending off everything from overnight robbery raids to full-scale invasion attempts by entire nations on the move. How were troops able to defend the Empire's vast territories from constant attacks? And how did they do so at such moderate cost that their treasury could pay for an immensity of highways, aqueducts, amphitheaters, city baths, and magnificent temples?

In The Grand Strategy of the Roman Empire, seasoned defense analyst Edward N. Luttwak reveals how the Romans were able to combine military strength, diplomacy, and fortifications to effectively respond to changing threats. Rome's secret was not ceaseless fighting, but comprehensive strategies that unified force, diplomacy, and an immense infrastructure of roads, forts, walls, and barriers. Finally, as barbarians began to penetrate the empire, Rome filed large armies in a strategy of "defense-in-depth," allowing invaders to pierce Rome's borders.
