(5) CRISIS OF THE THIRD CENTURY (235 – 284 AD)

 

Before the Fall came the Crisis…

With the Decline and Fall of the Roman Empire deserving first special mention, is it any surprise that the Crisis of the Third Century, that dress rehearsal of the fall, is far behind?

The Crisis of the Third Century – also known as the Military Anarchy or Imperial Crisis – had much the same scope as the decline and fall. Indeed, the Crisis of the Third Century was part of the decline, even if the empire narrowly forestalled its fall for another two centuries. Many of the fundamental problems of the empire from the Crisis endured to the fall, even when in muted form.

Narrowly forestalled its fall, that is, as in the empire “nearly collapsed under the combined pressure of repeated foreign invasions, civil wars, and economic disintegration” – “at the height of the crisis, the Roman state had split into three distinct and competing polities”, the so-called Gallic Empire and Palmyrene Empire vying with the central Roman Empire in its western and eastern provinces respectively.

Indeed, had it collapsed – or fragmented – it is hard to imagine the eastern half of the empire enduring in quite the same durable form as it did two centuries later. For one thing, the empire was divided into thirds rather than halves – with what was to become the eastern empire, that is, apart from the Palmyrene Empire, more resembling a quarter than half, albeit not unlike the eastern empire after it had rebounded from Arab conquests. It also lacked the capital founded by Constantine – Constantinople, with its nigh impenetrable defenses against all but the most overwhelming siege – or indeed the seat of imperial government founded as its own distinctive new Roman empire.

Although mind you, the eastern empire pulled off its own near miraculous recovery from crises – note that plural, crises – to rival that of the third century, like it looked back at the classical empire’s direst crisis and said hold my beer.

Two things saved the classical empire in the Crisis of the Third Century, even if it went from classical to late empire.

The first was that, as fearsome as the foreign invasions were, they lacked the ability or even intent to conquer territory or form their own states within the empire, rather than raiding it for plunder albeit on a larger scale than ever before. Even the Sassanid Persian Empire – the closest adversary the Roman Empire had to a rival peer state – for all its successes only raided Roman provinces and moved its border slightly away from its capital.

The second was a series of soldier emperors or barracks emperors – mostly the so-called Illyrian emperors originating from that region as the then heartland of the Roman army – who managed to hold the line and turn the tide to restore the empire, “an accomplishment many historians regard as about as unlikely and impressive as any of Rome’s Golden Age achievements in building the empire in the first place”.

Foremost among them of course was Aurelian – Restitutor Orbis or Restorer of the World, who reunited the empire by defeating the rival Palmyrene and Gallic Empires – but he built on the achievements of the emperors who came before him, Claudius Gothicus and arguably also Gallienus, and had successors who consolidated his achievements, notably Probus and the emperor who is credited with finally ending the Crisis, Diocletian.

At the core of the Crisis was the political instability of imperial succession (and usurpation) suggested by the other names used for the Crisis (Military Anarchy and Imperial Crisis).

Tacitus had observed that the ‘secret of the empire’ had been exposed with the succession crisis after Nero in the first century – “that emperors could be made elsewhere than in Rome”, a secret that excited “all the legions and their generals”.

Despite this observation, those legions and their generals had mostly followed the various imperial dynastic successions for the first two and a half centuries of empire – its founding Julio-Claudian dynasty, the Flavian dynasty, the adoptive succession of the Five Good Emperors, and the Severan dynasty.

In the Crisis, however, the legions and their generals had become very excited indeed – as one so-called barracks emperor succeeded another, usually by usurpation. And that’s just the line of imperial succession generally regarded as legitimate – beyond that there were literally countless usurpers, some of which we are still discovering through archaeology or coins.

Indeed, it often seems from the Crisis that where even the most minor commanders of a legion or legions had even the barest degree of military success (or were just left outside or stranded by the ebbing tide of imperial authority), they would proclaim themselves as emperor – or their legions would.

Not surprisingly, with Roman commanders and their legions marching either to advance their own imperial claims or against those of others, that saw them abandon the defense of the empire’s borders.

That was compounded by drain on population by the Cyprian Plague that raged through the empire, and which struck military barracks or manpower particularly hard – indeed the capture of Emperor Valerian by the Persians, the first time an emperor was captured by foreign forces, was attributed to his army being laid waste by plague.

The population decline of the empire also compounded its economic instability, characterized by the collapse of its currency and trade.

Through the gaping holes left in the imperial borders poured the empire’s recurring foreign enemies to raid it – further compounding the empire’s economic decline as the empire’s problems became an intense feedback loop as each problem cranked up the others.

Foremost in notoriety as the empire’s recurring enemies were the German barbarian tribes – who had grown in military capability (and relative population) through two centuries of contact with the empire, although they were not yet as capable as they were when they brought about the fall (and mostly replaced those Roman commanders and their legions vying within the empire).

The capabilities of the Germans were increased by forming new tribal coalitions or confederations – particularly the Franks, who raided across the Rhine through Gaul as far as Spain, and the Alemanni, who raided through the Alps into Italy, even threatening the city of Rome itself (the first external threat the city had faced for centuries) and giving Aurelian himself pause, inflicting his only defeat before he rallied to victory against them.

And across the Danube came the Germans who were ultimately to do more than anyone else to bring about the fall of the empire – the Goths, raiding as far as Greece and even Asia Minor because they managed to get themselves a fleet and there’s nothing worse than barbarians with boats.

All these German raiders paled in comparison to the Sassanid Persians – which as I noted was the only state on Rome’s borders that came close to being Rome’s peer – as they raided deep into Rome’s eastern provinces, particularly Syria.

As was typically the case, Rome’s worst enemy was itself as it fractured into three rival empires fighting among themselves. The core empire remained around Italy, fortunately including the Illyrian military heartland of the empire and its breadbasket in north Africa – but it lost its western provinces to the Gallic Empire led by usurpers, and its eastern provinces to the Palmyrene Empire, essentially a client state that had loyally led the defense against the Sassanid Persians but had gone rogue under its queen Zenobia.

Fortunately, along came Aurelian – breathing two centuries of life into the empire before the fall.
