Long before A.D. 476, the Roman Empire was plunged into a devastating crisis. The legions were no longer invincible, powerful new enemies were attacking the borders, one emperor after another was slain by conspirators, and traditional values were not enough to guide the bewildered and frightened populace. It seemed as if Rome, the city that had civilized the world, was on the point of inexorable collapse. At that precise moment three remarkable figures arose to lead the Empire on the path towards recovery: Gallienus, Aurelian and Diocletian. Drawing upon historical sources and modern theories of international relations, the author presents the strategic-military, economic and ideological measures that the empire implemented to overcome the Crisis of the Third Century. Reading his work, we do not only gain knowledge of the period; we are also able to extract possible lessons for the major empire of our times, the United States of America. "The Resurgence of Rome" is an authentic journey through one of the most crucial moments in our history.
