What if the world went through a pandemic just like COVID-19 in the Middle Ages?

In many ways COVID-19 was lucky, in the sense that it first appeared in China, a large industrial country with a lot of resources to dedicate to fight it, and in the second most powerful country today. It also appeared in 2020, at a time when due to world interconnectedness, at a time when we have many powerful tools available to fight it, at a time when we have a large supply of food and medicine. Imagine a world in which something like COVID-19 had happened in the 14th century, a time in which we were in the Middle Ages and long distance travel was either non-existent or very slow. No need to imagine anything, such a pandemic happened then and is famously known as the black death, it is said that it killed 50% of the population in Europe and 50 to 100 million deaths. The time in which this pandemic occurred is not comparable to the times we live in, everything was more difficult.<br><br>The results of the pandemic were disastrous, it is said that it took Europe more than 150 years to recover the population level it had before the pandemic began, it is said that the feudal system collapsed, Europe entered in what is called the late Middle Ages, a stage of great economic, cultural and population crisis, the Catholic Church lost a lot of power, it was at a very low level, it lost many faithful and much wealth, many conflicts in Europe and wars with Muslims began to take place. Imagine a world in which the black death had occurred in the 14th century, it is a possibility (it was also a real possibility).
