There are around 2.8 billion people in Europe, North and South America, Japan and India. A huge chunk of these people are middle class. Neither rich nor poor, the middle classes are able to obtain comfortable shelter, an adequate supply of food, clothing and basic utilities like electricity and sewer service, as well as education for their children and entertainment for themselves. But I wonder how many people in the middle classes know that they owe their existence… to a flea!
Well, not to a flea, exactly. But rather Yersinia pestis, a bacteria that piggybacked on the flea… which in turn piggybacked on rats in the holds of ships. You might have guessed that I’m talking about the Black Death (a.k.a. the bubonic plague) which happened in Europe and the rest of the world between 1347 – 1351. Little is known about the epidemic outside of Europe except that it was also found in the Middle East, India and China and killed around 75 million people worldwide – around 34 million of which were Europeans. Of course, most of us learned about the Black Death in high school, yet we were often never taught about what the disease actually meant at the time and what happened after the disease had run its course…. which is odd, because one of the most important things to come out of the Black Death was the middle class itself!
