Final answer:
The statement is true; the Mongol Empire's vast trade network, particularly the Silk Road, played a significant role in the spread of the bubonic plague, known as the Black Death, throughout Eurasia in the 14th century.
Step-by-step explanation:
By facilitating trade and communication throughout Eurasia, the Mongols indeed expedited the spread of the bubonic plague. This statement is true. The Black Death was greatly aided by the Mongol Empire's extensive trade routes, including the revitalization of the Silk Road.
These routes enabled not only the exchange of goods and culture but also inadvertently allowed diseases to spread across continents more rapidly. The bubonic plague, which initially impacted China, traveled along these routes to reach the Middle East and Europe, causing massive fatalities and societal changes.
The Black Death spread through Eurasia during the 14th century, resulting in an estimated 75 million deaths worldwide. It first afflicted the Mongol troops laying siege to the Genoese city of Caffa and was later transported to Europe via infected Genoese ships that docked in Sicily.
The Silk Roads played a critical role in enabling this widespread. With the Mongols' promotion of safe travels during the Pax Mongolica and increased movement of people, the pandemic was able to propagate and wreak havoc on a global scale.
