Smallpox and measles were common diseases as well as the bubonic plague that took a tool on the population; in Rome, for example, a smallpox outbreak along with other epidemic diseases and war decreased the population by one-fourth of the previous size. In China the spread of disease occurred at a later time but had similar effects. Additionally, economic issues may have contributed to the fall of the Roman Empire and the Han dynasty.

To begin their attack on Rome, Attila and his army attacked the Germanic peoples causing them to seep into the Roman empire for safety. Little resistance faced Attila and his army and they eventually led to western half of the empire destroyed.
