Which empire reopened and secured trade routes across Eurasia, enabling Pax Mongolica?

• A. Qin Dynasty
• B. Roman Empire
• C. Mongol Empire
• D. Mughal Empire

Answer: (C)

The idea being tested is how a single power can create safety and connectivity across long trade networks, making a peaceful era for commerce possible. The Mongol Empire did exactly that by uniting a vast stretch of Eurasia under one rule and prioritizing secure, reliable travel for caravans. They reduced banditry along the Silk Road, protected routes from China to Europe, and established a vast relay system that merchants could rely on. This enabled goods, ideas, and technologies to move much more freely across the continent, giving rise to the Pax Mongolica.

Other empires listed did not establish that continental-wide security and connectivity. The Qin Dynasty unified China but its impact was largely regional, not across Eurasia. The Roman Empire’s reach did not extend to East Asia, leaving Eurasian trade outside its sphere in practical terms. The Mughal Empire controlled parts of South Asia and adjacent regions, but it did not secure the broad Eurasian trade network in the way the Mongol Empire did.
