20th Century's Deadliest Disasters

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.
