Summary
Highlights
An unknown British poet in the 8th or 9th century explored the ruins of the Roman-era city of Bath. His poem, 'The Ruin,' describes the decay of what were once magnificent structures, now crumbling and overgrown. The poem itself, partially damaged by fire, reflects the fragmented nature of the past it describes, prompting contemplation about the builders and their eventual departure.
Paul Cooper introduces his podcast, 'The Fall of Civilizations,' which examines societies that rose and then disappeared. This episode focuses not on an entire empire, but on the Roman province of Britannia, from its unexpected creation to its eventual, dramatic collapse. The episode aims to understand how such a civilization endured, its fatal flaws, and the aftermath of its downfall.
By the time 'The Ruin' was written, Roman Britain was a distant memory. The Roman Empire, at its peak in the 1st century BCE, saw Britain as a mysterious and terrifying land beyond the 'known world'. Julius Caesar's failed invasions in 55 and 54 BCE, and later attempts by Augustus and Caligula, highlighted the difficulty of conquering the island. Caesar's descriptions of the painted, long-haired Britons depicted them as fierce and unpredictable.
Emperor Claudius eventually succeeded in adding Britain to the Roman Empire, landing four legions (20,000 men). After a two-day battle on the Thames, British resistance was crushed. Claudius marked his victory by arriving with a war elephant, a terrifying display of Roman power. Roman troops then swept across the country, subduing tribes, but faced fierce resistance from the Picts and Maetae in Caledonia (Scotland). The Romans struggled against the Picts' guerrilla tactics, eventually stopping their advance and building Hadrian's Wall as the final frontier of their empire.
South of Hadrian's Wall, Roman Britain saw a period of restless peace. Early rebellions, like Boudicca's, were brutally suppressed. Roman cities like London and Colchester rose rapidly, bringing urban planning, architecture, and luxury goods. Britain exported precious metals, especially tin, vital for bronze. However, Britannia remained a costly possession, with more resources invested than gained. Rural areas were centers of rebellion, and unlike other colonies, native Britons were rarely integrated into leadership, leading to persistent unrest and vulnerability to external raids by Picts, Scots, and Saxons.
By the turn of the 2nd century, Rome's 'Pax Romana' was cracking due to plague, famine, and civil wars. Absolute power made the emperorship a prize, and generals in distant provinces like Britain often saw opportunities for themselves. Clodius Albinus, governor of Britain, was the first to make the 'Brittunculi error.' In 195 CE, he took all troops from Britain to march on Rome, leaving the province undefended. This led to economic collapse, widespread rebellion, and barbarian incursions. Emperor Septimus Severus eventually crushed Albinus, but the cycle of Britain being stripped of its defenders for imperial ambition began.
The centuries following Albinus's defeat were marked by military anarchy and frequent rebellions in Britain, including a decade of separation from the empire under Postumus and rule by self-proclaimed emperor Carausius. By 306 CE, Constantine the Great was crowned emperor in York before successfully marching on Rome. However, the Empire weakened, and in 367 CE, the 'Great Conspiracy' unfolded. Mutinous Roman soldiers on Hadrian's Wall allowed Picts to breach the defenses. Coordinated barbarian attacks by Attacotti, Scots, and Saxons devastated Britain and Gaul, leaving Rome's authority shattered and shaking Roman confidence to its core.
Economic decline in Roman Britain was rampant, with infrastructure failing and industries dwindling. Magnus Maximus, a distinguished general and devout Christian, became governor in 380 CE. He saw an opportunity to seize the imperial throne, particularly after the unpopular Emperor Gratian alienated Rome by associating with Scythian archers and suffered a devastating defeat to the Goths. Maximus, like Albinus, stripped Britain of its entire garrison in 383 CE to march on Rome. He defeated Gratian but eventually fell. His departure left Britain defenseless, leading to widespread rebellion, economic collapse, and the final abandonment of Roman sites in parts of the province.
The last governor to make the 'Brittunculi error' was a common soldier named Constantine III. In 407 CE, he was elected emperor by his troops, again taking all legions from Britain to campaign on the continent. This decision, amidst barbarian invasions and civil wars, forced Emperor Honorius to officially declare in 410 CE that Britain was on its own. Rome withdrew its remaining soldiers and administrators, ceasing tax collection and military support. This left the Britons to their own devices, leading to local warlords, adoption of Continental mercenary armies (Angles and Saxons), and a shift away from Roman culture and language.
After Rome's departure, British towns and villas fell into ruin. Private baths became stagnant ponds, and grand structures like London's basilica were dismantled for materials. The population of London dwindled, reverting to rural existence as the city was consumed by nature. Archaeological evidence shows abandoned wells being filled and ritualistic objects left, suggesting a superstitious fear of the past. The Anglo-Saxons, impressed by the ruins but also viewing them as haunted, built their settlements away from them. The monumental Roman structures, incomprehensible to the new inhabitants, were attributed to giants, marking the profound cultural shift and the end of Roman Britain.
