395 AD
On August 24, 395 AD, the Visigothic king Alaric crossed into Roman territory, beginning a series of raids that would culminate in the Sack of Rome in 410 AD. Though this initial incursion was repelled, it marked the beginning of the end for the Western Roman Empire. The Gothic Wars would rage for decades, weakening Rome's ability to defend itself.
The Catholic Church played a crucial role during this period of collapse. St. Augustine, writing in North Africa, composed his great work 'The City of God' in response to pagans who blamed Christians for Rome's troubles. Augustine argued that the earthly city was always fragile, but the City of God was eternalβa message that sustained the Church through centuries of turmoil.
St. Jerome, living in Bethlehem, wrote: 'While Rome was being sacked, I was weeping.' The fall of the Roman world order would ultimately create the conditions for the Church to become the central institution of European civilization.
