43 The Fall of the Roman Empire

From 376–382 CE, Rome fought a series of battles against invading Goths known today as the Gothic Wars. At the Battle of Adrianople, 9 August 378 CE, the Roman Emperor Valens was defeated, and historians mark this event as pivotal in the decline of the Western Roman Empire. Various theories have been suggested as to the cause of the empire’s fall but, even today, there is no universal agreement on what those specific factors were. Edward Gibbon has famously argued in his The History of the Decline and Fall of the Roman Empire that Christianity played a pivotal role, in that the new religion undermined the social mores of the empire which paganism provided. The theory that Christianity was a root cause in the empire’s fall was debated long before Gibbon, however, as Orosius argued Christianity’s innocence in Rome’s decline as early as 418 CE. Orosius claimed it was primarily paganism itself and pagan practices which brought about the fall of Rome.

Other influences which have been noted range from the corruption of the governing elite to the ungovernable vastness of the empire to the growing strength of the Germanic tribes and their constant incursions into Rome. The Roman military could no longer safeguard the borders as efficiently as they once had nor could the government as easily collect taxes in the provinces. The arrival of the Visigoths in the empire in the third century CE and their subsequent rebellions has also been cited a contributing factor in the decline.
