The Impact of the Peloponnesian War on Athens

An outbreak of infectious disease brought down ancient Athens in the 5th century BC. The Cidides history of the Peloponnesian War gives a detailed description of this epidemic and its influence on the outcome of the war. In modern times, pandemics have had an important impact on Rome's development as a densely-populated empire. And first of all, the Antonine Plague brought Ramana to India; then you have a series of other pandemics over the next 500 years.
