In the first comprehensive history of the Horde, Marie Favereau shows that the accomplishments of the Mongols extended far beyond war. Favereau takes us inside one of the most powerful sources of cross-border integration in world history. The Horde was the central node in the Eurasian commercial boom of the 13th and 14th centuries and was a conduit for exchanges across thousands of miles. Its unique political regime - a complex power-sharing arrangement among the khan and the nobility - rewarded skillful administrators and diplomats and fostered an economic order that was mobile, organized, and innovative. From its capital at Sarai on the lower Volga River, the Horde provided a governance model for Russia, influenced social practice and state structure across Islamic cultures, disseminated sophisticated theories about the natural world, and introduced novel ideas of religious tolerance. The Horde is the eloquent, ambitious, and definitive portrait of an empire little understood and too readily dismissed. Challenging conceptions of nomads as peripheral to history, Favereau makes clear that we live in a world inherited from the Mongol moment.
