The Plague of Athens was a devastating epidemic which hit the city-state of Athens in ancient Greece during the second year of the Peloponnesian War (430 BC), when an Athenian victory still seemed within reach. It is believed to have entered Athens through Piraeus, the city’s port and sole source of food and supplies.
The city-state of Sparta, and much of the eastern Mediterranean, was also struck by the disease. The plague returned twice more, in 429 BC and in the winter of 427/6 BC. Modern historians disagree on whether the plague was a critical factor in the loss of the war. However, it is generally agreed that the loss of this war may have paved the way for the success of the Macedonians and, ultimately, the Romans.
The disease has traditionally been considered an outbreak of the bubonic plague in its many forms, but re-considerations of the reported symptoms and epidemiology have led scholars to advance alternative explanations. These include typhus, smallpox, measles, and toxic shock syndrome.
