Explanation:
The Mongol conquest of central Asia and eastern Europe played a significant role in the spread of the bubonic plague, also known as the Black Death. The Mongols created one of the largest contiguous land empires in history, which facilitated trade and communication across vast distances. With their extensive network of trade routes, known as the Silk Road, the Mongols allowed for the movement of goods, ideas, and unfortunately, also diseases.

The bubonic plague is believed to have originated in western China and Mongolia, where it was likely transmitted by fleas on rodents, especially the black rat. As the Mongols expanded their empire and came into contact with different regions and populations, they unknowingly carried the infected fleas and rats along with them.

The movement of the Mongols introduced the plague to new areas, including central Asia and eastern Europe. The disease spread rapidly along the trade routes, as merchants, travelers, and armies unknowingly carried infected fleas with them. The Mongol conquest created favorable conditions for the plague to spread, as large populations were displaced, and people from various regions were brought into close proximity.

Eventually, the bubonic plague reached Europe, where it caused devastating epidemics and resulted in a significant number of deaths. The movement of the Mongols played a crucial role in allowing the disease to travel from its original epicenter in western China and Mongolia to Europe, with devastating consequences for the affected populations.

D It allowed the plague to travel from its origin in western China and Mongolia to Europe.
