The Mongols created the largest land-based empire in human history under the leadership of Chinggis Khan in the 1200s-1300s. The Mongols conquered Central Asia and Northern China initially, then expanded west into Islamic lands and Central Europe. The Mongol Empire was later divided into four khanates or kingdoms that continued expanding the empire into Western Europe, the Middle East, North Africa, and all of China. While the Mongols brought death and destruction during their conquests, the resulting "Mongol peace" led to increased trade and cultural exchange along revived Silk Roads for approximately 100 years.
