410 CE
A year of profound psychological shock for the Roman world as Alaric and his Visigoths sacked the city of Rome, the first time the eternal city had fallen to a foreign enemy in nearly 800 years.
Conflict & Security
- Alaric and the Visigoths entered Rome on August 24 and sacked the city for three days, plundering wealth, seizing valuables, and taking hostages including the emperor's half-sister Galla Placidia.
- The sack was the first time Rome had been captured by a foreign enemy since the Gauls under Brennus had sacked the city in 390 BCE, a span of approximately 800 years.
- Although the physical destruction was relatively limited compared to later sackings, and churches were largely spared, the psychological impact on the Roman world was immense.
- Alaric and the Visigoths departed Rome after three days and marched south toward the Italian coast, intending to cross to Africa, but Alaric died later in the year near Cosenza in southern Italy.
- Roman Britain was effectively abandoned as Emperor Honorius reportedly told British communities to look to their own defense, marking the end of over three centuries of Roman rule in the island.
Geopolitics & Governance
- Emperor Honorius remained sheltered in the fortified capital of Ravenna, surrounded by marshes that made it virtually impregnable, while Rome was left largely undefended.
- The western Roman government under Honorius had executed the capable general Stilicho in 408, depriving the empire of its most effective military commander on the eve of the crisis.
Culture & Society
- The sack of Rome prompted intense theological debate, with pagans blaming Christianity for the abandonment of the old gods, and Saint Augustine beginning to write The City of God in response, arguing that the earthly city was always impermanent.
- Refugees from Rome fled across the Mediterranean, with many prominent Roman families relocating to North Africa, Palestine, and other provinces.
- The world population was approximately 212 million.
Climate & Environment
- Atmospheric carbon dioxide concentration was approximately 278 parts per million, as later confirmed by ice core analysis.
