What happened
With most of Eurasia's overland trade routes now under Mongol control, merchants could travel between China, Central Asia, Persia, and Europe under a single set of rules and protections, a period historians call the Pax Mongolica. At Karakorum, the Mongol capital, merchants were drawn by the khan's practice of paying generous, often double-market prices for goods, and the city developed large regular markets trading everything from livestock to luxury goods. The empire also maintained an extensive postal and relay system, with stations set roughly every 25 to 30 miles along major roads, each offering lodging and fresh horses for envoys and travelers, a system later described in detail by Marco Polo.
Why it matters
By removing the many separate tolls, borders, and hostile territories that had previously fragmented the old Silk Road, the Mongols made long-distance Eurasian trade and travel dramatically more practical for a century, enabling figures from William of Rubruck to Marco Polo to cross the continent and report back on what they found. The same open routes would later carry the Black Death west from Central Asia.
How we know
The Pax Mongolica's effects on trade and the postal relay system are described in the World History Encyclopedia's articles on Karakorum and Marco Polo, drawing on Marco Polo's own travel account and Mongol administrative practice.
