The scale of Rome's fall is staggering. The city shrank from feeding roughly one million people to perhaps just 30,000 over a few centuries. Aqueducts fell silent, forums filled with mud, and the population of Roman Britain collapsed entirely. Archaeologists actually see this in the soil, where coins and pottery simply stop appearing and all evidence of occupation vanishes from the layers.
