How Did a Small Earthquake in Rural China Become the Disaster of Europe?

A rather insignificant earthquake occurred in one of the rural areas of China, but thousands of people, especially Europeans, would die from this earthquake.
Even small changes in the initial data of a system lead to large and unpredictable consequences in chaos theory. In the famous example of Edward N. Lorenz, who tries to explain the subject in the simplest way, it is said that the flapping of wings of a butterfly in the Amazon Forest can cause storms in the USA. For this reason, this situation is called the butterfly effect.

In our series of Butterfly Effect articles, we will explain how events that seem very mundane or very mundane can have big effects. From time to time we will go to the World Wars, and sometimes we will examine some events in different countries.

It all started with an earthquake in China

In 1288, the earthquake that took place in Fruili, located in the north of Italy, was regarded as the harbinger of the future dark days, death and disaster in Medieval Europe, where there were 27 superstitions per person. The earthquake that would trouble them was not the earthquake that happened in Fruili.

Tian Shen, one of the rural areas of China at that time, was also shaken by an earthquake during the same period. This earthquake is not something that will burn and be called a major disaster. The important thing is that this area is home to a large number of Chinese Black Mice.

There were plenty of fleas in the mice in the area. These fleas could carry the disease called Bubonic Plague. Both mice and fleas continued to live without worrying about this disease, as both species were immune to the bubonic plague.

Under normal conditions, mice were the target of fleas. Moreover, these little creatures could actually survive for 5 months without being fed. Although the mice fled after the earthquake, they faced another threat: the Mongols.

The Mongolian military order opposed the burning down of the land. Because the lands seized were of great importance for the future. For this reason, the Mongolian army passing through the Shin Zen region after the earthquake did not burn the crops and did not harm the environment. The rats that spread throughout the region also infested the army carrying ready meals.

The Mongols, who defeated every enemy they could see, were a community that knew how to fight rats. They solved the mouse problem in a short time. What bothered them would be the fleas, their enemies, which they are not easy to see.
