What happened
In 1206 a Mongol confederation declared Temujin, who took the title Genghis Khan, universal ruler of the Mongol tribes, and over the following decades his armies and his successors' armies extended Mongol control across the Central Asian steppe, into northern China, and west toward Eastern Europe. By the time of Genghis Khan's death in 1227, the resulting empire ran from China's Pacific coast to Eastern Europe, and because the Silk Road's network of routes had fallen entirely under a single power's control, it became dramatically safer to travel than it had been under the fragmented, warring kingdoms that previously controlled separate stretches of it. National Geographic's educational resource on this period, known as the Pax Mongolica or "Mongol peace," credits Mongol administrative innovations, including a relay postal system and explicit safe-conduct guarantees for merchants, with lowering the practical risk and cost of overland trade across the entire route for the first time in its history.
Why it matters
A single political authority controlling the whole distance from China to Europe, something no earlier power on the Silk Road had achieved, is what let travelers like Marco Polo and Ibn Battuta make journeys of thousands of miles relying on official protection rather than negotiating passage separately with dozens of independent rulers.
How we know
National Geographic's education resource on the Pax Mongolica summarizes the political and administrative changes that followed Mongol conquest, based on the well-documented territorial expansion of the Mongol Empire after 1206 and the standard historical record of Mongol trade and postal administration.
