At its height, the Mongol Empire covered a geographic expanse that stretched from East Asia to parts of Eastern Europe and the Middle East. Founded by Ghengis Khan, who died circa 1227 CE, it would later be divided into four Khanates, each acting independently of one another and pursuing their own separate agendas. The Khanates would eventually collapse in the fourteenth century.

What was the largest contiguous empire in history?

The Mongol Empire was the largest contiguous empire in history. Established by the famed conqueror Genghis Khan in the early thirteenth century ACE., it was based in modern Mongolia. At its height, the empire spanned most of modern Asia, from the Korean peninsula to the modern Middle East and the frontier of Europe.

Like most great empire-builders, the Mongols established their empire through a combination of military force and diplomacy. Their military success was based on the highly mobile and utterly terrifying cavalry forces that Genghis Khan and his successors deployed first against Chinese emperors and then against rivals in Central Asia along the Silk Road. By his death, Genghis Khan had mostly subjugated a series of Chinese rulers, conquered the Khwarezm Empire in Central Asia, and pushed to the modern-day Caucasus, near the borders of the Russian Empire.

Subsequent leaders added to the Great Khan's conquests and generally honored his policy of religious tolerance. The backbone of the empire was the Silk Road, the network of trade routes that linked China to the Middle East and Europe. Though their conquests cost hundreds of thousands of lives, the Mongols also fostered trade, established a census of the empire, and generally observed local customs.

The Mongol Empire declined and ultimately collapsed in the fourteenth century, but its sheer expanse permanently altered the cultural landscape of Asia. Moreover, successive emperors who claimed to be the heirs of the Mongols ruled over much of Central Asia for centuries.
