The social conditions of the Middle Ages contributed to the spread of the Black Death due to the unsanitary conditions of the time.
The Black Death was a pandemic that occurred during the Middle Ages in which, according to studies, 70% of the population of Europe died. This pandemic was transmitted through the bite of the rat flea and produced rashes on the skin of the infected.
During the Middle Ages, kingdoms were small towns where people congregated to buy goods and access some services. Therefore, this agglomeration of people made it much easier for fleas to infect several people.
On the other hand, at that time the sewage and waste treatment systems were primitive, so the rats reproduced easily, being the mechanism of spread of this disease. On the other hand, trade also contributed to the rapid spread of the plague as rats slipped onto transport and their fleas subsequently infected people elsewhere.
