Why did population decline in medieval Rome and Europe?

Following the fall of the Western Roman Empire, late antiquity and the Early Middle Ages were marked by severe population decline, counterurbanisation, and political fragmentation. Although Europe experienced a significant demographic recovery during the High Middle Ages, late medieval crises like the Black Death and recurring famines caused widespread depopulation across the continent.

What we know

• Widespread population decline and counterurbanisation began across former Roman territories in late antiquity and persisted into the Early Middle Ages. [3]
• Following the collapse of Western Roman authority, political control of Rome transitioned to the Papacy, leading to the establishment of the Papal States in the 8th century. [3, 5]
• European population levels expanded significantly starting around 1000 CE during the High Middle Ages, driven by agricultural innovations and warmer climate trends. [2, 3]
• The Black Death pandemic between 1347 and 1350 reduced the total population of Europe by approximately one-third to one-half. [3, 4]
