The Plague of Justinian (AD 541â542) was a pandemic that afflicted the Eastern Roman Empire, including its capital Constantinople. At its peak, 5,000 people per day in Constantinople died from it, killing half the population. From there, the plague moved east and west, becoming antiquity's most lethal known pandemic.
Among the many causes of the fall of the Roman Empire was wars with Persians, which cost the empire much of its strength. But I believe there were other causes that were more â¦important, including civil wars and invasions of migrating Germanic peoples. For more information, please use the link below.
