Tamerlane: Sword of Islam, Conqueror of the World. Justin Marozzi

divine assistance was sought and victories celebrated. There were no temples, nor organised worship as it is understood today. Horses were often sacrificed to Tengri, and were killed and buried with a man when he died so he could ride on into the afterlife. Shamans, venerated figures in Mongol society, acted as mediators between the natural and supernatural worlds, falling into trances as their souls travelled to heaven or the underworld on their missions to assist the community. Clad in white, mounted on a white horse, resplendent with a staff and drum, the shaman enjoyed distinguished status among the nomads, distributing blessings to herds and hunters alike, healing the sick, divining the position of an unseen enemy and the location of the most favourable pastures. Religious tolerance has come to be inherently associated with the Mongols, for they demonstrated a remarkable open-mindedness towards the other faiths they encountered.

      Gibbon was much taken with this aspect of the Genghis legacy. ‘The Catholic inquisitors of Europe who defended nonsense by cruelty, might have been confounded by the example of a barbarian, who anticipated the lessons of philosophy and established by his laws a system of pure theism and perfect toleration,’ he wrote. So moved was the magisterial historian he even suggested that ‘a singular conformity may be found between the religious laws of Zingis Khan and of Mr Locke’. The Mongols proved less dogmatic than the monotheists who travelled through their lands, be they Christian, Muslim, Jew or Buddhist. In the course of their pouring west across Asia towards Europe, they came to accept the religion of the peoples they conquered, be it Buddhism in China or Islam in Persia and the Golden Horde of southern Russia. This did not prevent them clinging on to vestigial aspects of shamanism, however, one reason no doubt why the great powers of the Islamic world never ceased to consider Temur a barbarian rather than a true Muslim.

      If religion left only a light imprint on the Mongols, their contributions to culture were still less visible. Though their artistic achievements have been praised – they were talented carvers in bone, horn and wood, and produced handsome cups and bowls and elegant jewellery – theirs was not a literate world. An illiterate race prior to Genghis, they left virtually no written record of their time. The thirteenth-century Secret History of the Mongols, a document of questionable accuracy, is the only substantial survivor. An indication of their sophistication, however, is given by the yasa, an obscure body of laws codified by Genghis as head of a growing empire. It remains shadowy, because no complete code has ever been discovered. Historians have had to rely on the numerous references to it in the chronicles. According to Ata-Malik Juvayni, the thirteenth-century Persian historian of the Mongol empire, the yasa governed ‘the disposition of armies and the destruction of cities’. In practice it was an evolving set of regulations touching on all aspects of life in the horde, ranging from the distribution of booty and the provision by towns and villages of posting stations with horses and riders, to the correct forms of military discipline on the battlefield and how to punish a horse thief (the animal had to be returned to its owner with a further nine horses thrown in for good measure; failure to observe these terms could result in the thief’s execution). The yasa appear to have governed everything from religion (mandating toleration and freeing clergy of all taxation) to the uses of running water (prohibiting urination or washing in rivers, which were considered sacred).

      The descriptions of fourteenth-century Tatars reveal the obvious parallels with the thirteenth-century Mongols who had preceded them. In particular, observers remarked on their physical hardiness and legendary military skills. The Tatars, wrote Ruy Gonzalez de Clavijo, the Spanish ambassador sent to Temur’s court by Henry III of Castile in 1402, could withstand ‘heat and cold, hunger and thirst, more patiently than any other nation. When food is abundant, they gorge on it gluttonously, but when there is scarcity, sour milk tempered with boiling water suffices them … for their cooking fires they use no wood but only the dried dung of their herds, and it makes the fire for all purposes of roasting and boiling.’

      Fighting was in their blood. Famed for their skill as archers, they charged across the steppe on horseback, raining down arrows upon their enemies. ‘They were archers who by the shooting of an arrow would bring down a hawk from the hollow of the ether, and on dark nights with a thrust of their spearheads would cast out a fish from the bottom of the sea; who thought the day of the battle the wedding night and considered the pricks of lances the kisses of fair maidens.’ They were great hunters, too, forming circles many miles in diameter and then riding inwards, driving all the wild beasts before them to their slaughter. It was a sport which honed their military talents and filled their stomachs, celebrated with wine-drenched banquets that lasted deep into the night. By day they tended their animals, riding out to pastures to allow their horses, camels, goats and sheep to graze. This was the currency of everyday life, and when a man wanted a wife, he bought one with animals or grazing rights. If he was rich, he bought several. Polygamy thrived in the upper reaches of society.

      For ordinary men and women, the clothes were coarse and simple, long buckram jackets which protected the wearer from the elements. Silks, fine cloths and gold brocade were the preserve of the princes. In battle they made a formidable sight. Their enemies found them terrifying to behold. Amir Khusrau, an Indian poet who was captured by Temur’s hordes at the close of the fourteenth century, recalled their appearance with horror.

       There were more than a thousand Tatar infidels and warriors of other tribes, riding on camels, great commanders in battle, with steel-like bodies clothed in cotton; with faces like fire, with caps of sheep-skin, with heads shorn. Their eyes were so narrow and piercing that they might have bored a hole in a brazen vessel … their faces were set on their bodies as if they had no neck. Their cheeks resembled soft leather bottles, full of wrinkles and knots. Their noses extended from cheek to cheek, and their mouths from cheekbone to cheekbone … their moustaches were of extravagant length. They had but scanty beards about their chins … they looked like so many white demons, and the people fled from them in affright.

      Conflict between the Mongol khanates of Genghis’s successors, which held the lion’s share of Asia in an unforgiving grip, was the harbinger of conflict within them. In the late thirteenth century, serious strains began to emerge in the Chaghatay ulus. There were tensions between the settled nobility in the towns and villages, largely in Mawarannahr, which had embraced Islam, and the nomadic, military aristocracy to the east, which rejected it and clung on to their pagan beliefs. These aristocrats, for whom the settled life of the conquered peoples was anathema, came to refer scornfully to their neighbours as qurannas (half-breeds or mongrels), an insult returned by the western Chaghatays, who called them jete (robbers), or Jats. Within the ulus, the geographical divide between east and west – the Tien Shan, or Celestial Mountains, whose peaks soar more than twenty-three thousand feet – was as dramatic as the ideological gulf which separated them. Increasingly, both sides stared across it with hatred in their hearts. Tensions were further escalated by the system of privileges granted to the military by the khan. These imposed crippling burdens on the poorer members of the local population, who were forced to feed, clothe and arm the warriors.

      In 1266, the Chaghatay khan Mubarak chose to be enthroned in Mawarannahr, rather than in the nomad camp established by Chaghatay on the river Ili in south-eastern Kazakhstan, several hundred miles to the east, as was customary. For the military aristocracy, this symbolic ceremony, which expressed a preference for one way of life over another, represented a direct challenge to their traditions and authority. Worse, Mubarak was subsequently seduced by the siren calls of Islam, a conversion which sent seismic shocks across the heart of Central Asia and opened a growing chasm between East and West. A qurultay, an assembly of Mongol notables, was called in 1269 to determine the future of the ulus. In it, the warrior horsemen of the steppe prevailed, ruling against both settlement in the towns and the use of their cattle to tend agricultural land. Instead, the hordes would roam across the steppe and the mountains, grazing their hardy mounts on the pastures in accordance with the ancient ways. Mubarak was summarily dethroned. For the next fifty years, the pagan aristocrats held the ground.

      But the seeds of change planted by Mubarak continued to take root even after his ousting. The soil was fertile. The Mongol warlords who had accompanied Mubarak to Mawarannahr, who included the Barlas clan, Temur’s tribe, had by the opening of the fourteenth century converted to Islam and been Turkicised. The qurultay of 1269, however clear its conclusions, had not proved decisive. The
