What brought the deadly pestilence from the Orient?

The deadly pestilence, commonly referred to as the Black Death, was brought to Europe primarily through trade routes, particularly the Silk Road, during the 14th century. It is believed to have originated in Central Asia and spread via fleas on rats that traveled on merchant ships. The rapid movement of people and goods facilitated the transmission of the disease, leading to widespread mortality across Europe. Additionally, poor sanitary conditions and limited medical knowledge exacerbated the outbreak's impact.
