Although it is the name of Genghis Khan that is synonymous with the great conquests of Asia and the attacks on lands far beyond, the Mongol leader died in 1227 after the initial phase of empire building in China and Central Asia had been carried out, but before the dramatic attacks on Russia and the Middle East and the invasion that brought Europe to its knees. It was his son Ögödei who oversaw the expansion that massively increased the extent of Mongol lordship, masterminding campaigns that extended into the Korean peninsula, Tibet, Pakistan and northern India – as well as in the west.
