It was near the 13 - 14th century, and people were going on with their normal lives in medieval London. But, far away, almost on the other side of the world in China, a plague had erupted. It was killing many people, and it soon spread through parts of Asia. People would return, telling the Europeans the story of a plague that killed many people. They named it the Black Death. It wasn’t very long until one of the travelers hadn’t been cautious enough, caught the black plague, and sailed home on the ships. But trades weren’t the only ones bringing in the deadly plague. The Mongols, who were known to move around and conquer territory decided to head for Europe next and they too, were suffering from the Black Death. The Mongols attacked Caffa, which is near the Black Sea. The Mongols decided that they would catapult their dead corpses that were victimized by the Black Death, over to the people of Caffa. This was one of the first ever recorded events of biological warfare. Soon, the people of Caffa were suffering from the Black Death too. Since Caffa was a trading city, many people would go back and forth with ships and trades to trade their goods. This made it very easy for the plague to infect more people as days and night swept by. But was the Black Death just some kind of spirit or bad air that floated around, infecting who it wanted? No, it was actually carried by fleas, which would stay in the rodent’s furs. That is why, when a human or rodent died of the plague, the flea could easily hop onto another victim to infect. It was easy for the rats and fleas to get around for multiple reasons: One, people would kill cats in belief that they worked with witches and the devil, making the rats thrive. Two, it was quite unhygienic in the towns, no one washed themselves, and it was very dirty. Three, people just didn’t know what they were dealing with. Some would think that it was God that sent down the plague as punishment for the people’s sins, leading people to believe that if they punished themselves, they would be forgiven for their actions. Christians would punished themselves by whipping themselves, drawing blood on themselves, and by many more gruesome ways, out displayed in public for everyone to see. It was quite a tough time. The Black Death affected society too. Children, they were orphaned after their parents passed away from the Black Death. They were at risks of dying, because of their malnutritioned states, unsanitary surroundings, and weak bodies. Most children had to work jobs then, because the people didn’t know about how a child’s mind developed. It did not only affect the children, but also the feudal system. This system usually consisted of monarchs at the top, followed by nobles, merchants, peasants, slaves, etc. But when the plague started killing many peasants, the nobles didn’t have anyone to work for them. This meant that the remaining peasants could ask for a higher salary, rebel against monarchs/nobles, or even move to another place to own their own place to earn money. The Black Death killing someone was not a pleasant sight to watch. The symptoms of this plague included: high temperatures, chills, coughing, vomiting, diarrhea, rapid heartbeats, infection of the respiratory system and bloodstream, and lastly, buboes. Buboes were swellings that were commonly found in the groins or armpits, growing up to the sizes of eggs. They started off red, but then would turn to an ugly purple or black. Some fake “doctors” thought that by bursting the buboes, the evil or dirty pus would come out, and it would be fine again. But that didn’t solve the problem. They were very painful, these symptoms and buboes, and people who got the Black Death would go through this agonizing pain for up to 4 days before dying. If a victim survived 5 days, there would be a very small chance that they would be able to make it out alive. But that was only a very few of them. The Black Death had taken the rest of the lives with him, counting almost up to 25 million, taking ¼ of the population. The Black Death has drastically changed our history and changed our view on how we see things. The Black Death, also known as Yersinia Pestis, still exists, but only in the deepest forests. And nowadays we have found more ways to keep off this bacterial plague.
