The disappearance of the Black Death is due to natural selection and survival of the fittest.

We all know that Black Death was the symbol of death in Europe at that time, and it spread directly from Italy to Russia in just 6 years. In addition, the sanitary conditions at that time were extremely poor, and there was no way to suppress the spread of the plague. Therefore, the Black Death caused many deaths. As long as someone was infected, they basically received an invitation from the God of Death.

It is precisely because those infected people have weak body resistance that they are eliminated, and fewer and fewer people carry new disease sources. In addition, as time goes by, they have developed a sense of isolation. Those with weak constitutions who were infected were eliminated because of this, and those with better constitutions who were not infected took isolation measures in place. After the pathogens of the Black Death killed their original speed, they could not find the next one. The family can only be destroyed because of this. So the Black Death slowly ended.

The Black Death is naturally a disaster in European history, but this epidemic has caused the autocratic status of the European church to directly decline. More and more people have begun to believe in science and do not listen to those churches. According to rumors, Europe also moved directly from the darkness of the Middle Ages to the Renaissance, and the direction of the development of civilization in Europe and even the world was changed. While the Black Death took away people's lives, it also brought a bright culture to the entire world.

In addition, the spread of the Black Death is very strong. As long as one person is infected, basically the entire family will die. Therefore, many European nobles mostly inherit their inheritances from their relatives, so a few Heirs inherit the entire estate of most families and immediately become rich. The distribution of wealth can only be regarded as property in the eyes of people without brains, but among those with business acumen, it becomes capital that can be utilized. It is precisely because of the inheritance of property that European capitalism began to flourish.
