PThe Black Death was one of the most devastating pandemics in human history, resulting in the deaths of an estimated 75 to 200 million people and peaking in Europe in the years 1348–50 CE.   Although there were several competing theories as to the etiology of the Black Death, analysis of DNA from victims in northern and southern Europe published in 2010 and 2011 indicates that the pathogen responsible was the Yersinia pestis bacterium, probably causing several forms of plague.

The Black Death is thought to have originated in the arid plains of central Asia, where it then travelled along the Silk Road, reaching the Crimea by 1346.   From there, it was most likely carried by Oriental rat fleas living on the black rats that were regular passengers on merchant ships. Spreading throughout the Mediterranean and Europe, the Black Death is estimated to have killed 30–60% of Europe’s total population. All in all, the plague reduced the world population from an estimated 450 million down to 350–375 million in the 14th century.


The aftermath of the plague created a series of religious, social, and economic upheavals, which had profound effects on the course of European history. It took 150 years for Europe’s population to recover. The plague reoccurred occasionally in Europe until the 19th century.

This subject is very depressing.  The following from Monty Pythons should help relieve the depressing subject.

  1. I’ve always had a morbid fascination with the plague, primarily because, as you mentioned, it had such a profound influence on society, culture, and the arts at the time. Truly cataclysmic. The plague is still with us, and there’s no reason that it could not recur in a mutated form in future. We have antibiotics to treat it, but with the rise of resistant strains…who knows?

    OK-I LOVE Monty Python and I was thinking about this while reading your post and then there was the scene-lol It’s sad to think how devastating this was and I hope we never have to face this again. During that time-being clean was not their priority plus, due to fear of witchcraft, they killed a lot of cats especially black ones which did not help since the rat population exploded. I will now since Ring around the Rosy

    It’s unbelievable how many people in the entire world died from this leaving such a small percentage. It was apparently brought to the UK in bales of cloth containing infected fleas.

    Trust Monty Python to cheer us up with their irreverent but hilarious take on it.
