What specific internal societal defects precipitated the ultimate collapse of the Roman Empire? Michael Grant, a noted classical historian, examines the multifaceted decline of Rome by moving beyond singular explanations. He utilizes a framework of thirteen distinct internal flaws to argue that the empire's disintegration was primarily a result of systemic social and political erosion that rendered the state vulnerable to external pressures.

Historians and students of classical antiquity frequently cite this work for its structured approach to a complex historical problem. Readers often note that Grant's prose remains accessible while providing a rigorous analytical framework for understanding the decline of a superpower.
