Moral decadence did not contribute to the fall of the Roman Empire, but political instability that was most strongly reflected in a weakened army did, writes Hans Delbrück in volume 2 of
History of the Art of War
. The rise of sectionalism and the constant overthrowing of emperors left the empire without a secure superior authority demanding the loyalty of the legions and without the money to support them. Delbrück’s celebrated work traces the collapse of the Roman military system and its replacement with barbarian mercenaries by the fourth century, following the invasions by the Germanic peoples.
The Barbarian Invasions
opens with a discussion of the military organization of the early German tribes, compares it with that of the early Roman legions, and goes on to show how tactics and strategies changed after entire peoples such as the Goths, Vandals, and Burgundians migrated to Roman soil and formed an uneasy alliance with the Romans. It ends with an examination of the decline of the Germanic-Romanic military system in the Middle Ages and the rise of the feudal system.
