3. Before the Black Death, There Was Justinian’s Plague
The Black Death was history’s deadliest plague. Tragic and lethal as it was, Justinian’s Plague, 541 – 542 AD, gives it a run for its money in deadliness and long-lasting consequences. It was named after the Byzantine Emperor Justinian I, during whose reign it occurred – and who came down with it, but survived. Justinian’s Plague is history’s first known recorded pandemic, because it swept across three continents, Europe, Asia, and Africa.
Like the Black Death, Justinian’s Plague was caused by the Yersinia pestis bacterium. Also like the Black Death, Justinian’s Plague struck with a devastating initial outbreak, followed by several recurrences in succeeding years. By the time the last recurrence ended, Justinian’s Plague had killed an estimated 25 million to 100 million people.
2. Black Rats Carried the Plague Across the World of Late Antiquity
The strain of Yersinia pestis bacterium responsible for Justinian’s Plague originated near Central Asia, near the border between modern China and Kyrgyzstan. Like the Black Death, Justinian’s Plague was mainly bubonic, felling its victims with all the bubonic plague’s tragic horrors. It first struck China and northern India, made its way via trade routes to the Great Lakes region of Africa, then down the Nile to Egypt.
Like the Black Death, Justinian’s Plague was transmitted by infected fleas carried by black rats. Egypt was the Byzantine Empire’s granary, and from its seaports, ships laden with grain – and also rats hosting infected fleas – sailed across the Mediterranean. From Egypt, the plague rapidly spread to the rest of the Middle East, the Eastern Mediterranean, and Constantinople, which served as both capital and commercial center for the Byzantine Empire. From Constantinople, the plague swiftly spread through the rest of Europe.
1. Justinian’s Plague Ended the Classical Age, and Kick Started the Feudal Era
Justinian’s Plague hit Europe hard: an estimated 40% to 50% of the continent’s population perished during the pandemic’s tragic course and aftermath. However, not all parts of Europe were equally hard-hit. The plague followed the established trade routes, so ports and cities got the worst of it. By contrast, the countryside and the parts of Europe of the established trade routes got off relatively lightly.
That uneven death toll, heavy in the cities and relatively light in the countryside, transitioned Europe out of what was left of the Classical Age, and ushered in the Feudal Era. The Classical Age had been marked by a significant urban culture. Justinian’s Plague – on top of Justinian’s many wars – put paid to that, devastating the cities and an economy built around sustaining urban life. The center of power shifted from the cities to the countryside, and rural strongmen emerged as the founders of feudalism. One era and way of life ended, and another one began.
