When I first visited the complex of Buddhist cave grottoes, dating from the fifth to the 14th century, at Bezekilk in Xinjiang province, China, I was struck by the destruction wreaked on them by Muslims whose religion proscribes figurative images of human beings. Eyes had been gouged out and figures lacerated with knives. When and by whom had the vandalism of these exquisite and colourful portraits been done? I later learnt that the Buddhist Uyghurs of the Kingdom of Qocho and Turfan, in which Bezekilk was situated, were converted to Islam by conquest during a holy war at the hands of the Muslim Chagatai Khizr Khwaja. Not easy information to assimilate.
The activities of Genghis Khan and the Mongol hordes are widely known but not always in detail. What dynasties did they sweep away on their destructive paths of pillage and conquest? Many of the dynasties they conquered were under the influence of Islam. Yet in their turn, these Muslims had overcome Sogdian princedom resistance in the ninth century. Central Asian history can be confusing for the non-specialist.
Into this confusion steps Christoph Baumer with a masterly third volume in his four-volume series on Central Asia, covering the Age of Islam and the Mongols. With his consummate academic and archaeological professionalism, Baumer cuts through the historical smokescreen and gives a detailed and authoritative account appropriate for both scholar and layman alike.
He explains that prior to the eighth century, Islam had established itself in Central Asia through a combination of Iranian book and Turkish sword. Turkic-Muslim dynasties were established and Islam offered these new dynasties an ideological method of breaking down borders between warring clans and tribes.
By the mid-11th century, science, scholarship and the arts flourished as this newly established Central Asian hegemony spread to other parts of the Muslim world.
