The black death, or Bubonic Plague, came from a bacterium now known as Pasteurella pestis. It was carried by fleas who, in turn, attached to rats on merchant ships coming from the East of Europe. These rats then transmitted the disease, which also was contagious to humans. All it took was for one human to get bitten by a rat or flea and he or she would have the bubonic plague.

How did the europeans know anthrax wasnt the black death?

Because, Anthrax and the Bubonic plague, also known as Black Death are two different types of diseases. African mammals were often infected with Anthrax, and the spores could have easily reached Europe through air currents. This evidence suggests that Anthrax was present at the time of the Black Death and was responsible for or at least contributed to the great many deaths the plague caused. But whether or not it was the cause of the Black Death, or simply aided the Bubonic Plague in some capacity in making people sick, remains unclear.

Was the black death a natural disaster?

The Black Death, also known as the bubonic plague, was not a natural disaster in the traditional sense. It was caused by the bacterium Yersinia pestis, which was transmitted to humans through fleas on rodents. While the initial outbreak was a result of natural processes, such as the interaction between humans, rodents, and fleas, the spread of the disease was exacerbated by factors such as trade routes and lack of medical knowledge and infrastructure. Therefore, the Black Death was a natural epidemic rather than a natural disaster.
