their lips which are as sweet as the berries of the breasts.’

      Cities were razed and depopulated, prisoners slain or ordered to march as a shield before the army, in full battle formation. Even cats and dogs were killed. Marching through Azerbaijan, the invaders sacked the Christian kingdom of Georgia in 1221, flattening the capital of Tiflis (Tbilisi). Through the Caucasus and the Crimea and along the Volga they advanced, routing Bulgars, Turks and Russian princes as they hugged the northern shores of the Caspian Sea. Another siege was mounted against Urganch, homeland of the shahs. After seven months of resistance, the city was stormed. Artisans, women and children were gathered to one side and enslaved. The remaining men were put to the sword. Each of Genghis’s soldiers was ordered to execute twenty-four prisoners.

North of the Oxus the Mongols fell upon the ancient city of Termez, where legend has it that a woman begged to be spared the massacre, telling her captors she had swallowed a pearl. Her stomach was ripped open and the gem removed, prompting Genghis to order his men to disembowel every single corpse. Balkh, the fabled former capital of the Bactrian empire, collapsed before the Mongol onslaught, followed by the city of Merv, where the forces of Tuli, another of the warlord’s sons, reportedly slew seven hundred thousand.^* Herat, Nishapur and Bamiyan likewise folded. In the dying months of 1221, Jalal ad-din, who had led the resistance to the Mongols after the ignominious flight of his father Mohammed, was defeated at the battle of the Indus, which marked the end of the campaign. In 1223, Genghis returned east. He died four years later, ruler of an empire which spanned an entire continent from China to the gates of Europe.

      Though none of his successors was possessed of such savage genius, the Mongol conquests Genghis initiated were vigorously expanded by his sons and grandsons. The territories he had won were distributed according to custom. Tuli, the youngest son, received his father’s seat in Mongolia. Jochi, the eldest, received lands farthest away from Karakorum, west of the Irtish river in what later became the regions of the Golden Horde, the Russian khanate which is discussed in Chapter 2. Ogedey, the third son and future Great Khan, or royal leader above all his brothers, was given the ulus (domain) of western Mongolia. Genghis’s second son Chaghatay received Central Asia as his inheritance. It became known as the Chaghatay ulus, the western half of which formed the Mawarannahr in which Temur grew up.

      By 1234, Ogedey’s conquest of the Chin empire was complete. The 1240s and 1250s saw Mongol rule spreading west across southern Russia into eastern Europe under the leadership of Genghis’s fearsome grandson Batu, founder of the Golden Horde. At the same time, another grandson, Hulagu, was conquering his own territories by the sword, establishing an empire which included Georgia, Armenia and Azerbaijan in the west, Baghdad and the Fertile Crescent in the south, and ranged as far east as Khorasan, eastern Persia. Founder of the Ilkhanid dynasty of Persia, Hulagu was helped in his conquests by Mongol troops belonging to his brother Great Khan Mönke, together with detachments from both Batu and Chaghatay. United, the khanates proved invincible.

      History suggests it is easier to carve out an empire than preserve it, and the fate of Genghis’s successors proved no exception to the rule. With the death of Great Khan Mönke in 1259, the great age of Mongol conquest ground to a close. In 1260, the Mongol army was defeated at the battle of Ain Jalut by the Egyptian army under Baybars, who became the first Mamluk sultan later that year. Africa closed her doors forever to the pagan invaders from the east. The Sung empire of southern China fell to Genghis’s famous grandson Kubilay in 1279, but by that time the Mongol empire had been torn apart by infighting for two decades. Instead of uniting to extend their dominions in the west, the Golden Horde and the Ilkhanid dynasty had embarked in 1262 on a long series of wars over the pasturages of Azerbaijan and the Caucasus. At the same time in the east, the house of Tuli was disintegrating as Kubilay and his brother Arigh Boke fought a four-year civil war for the imperial throne. As the thirteenth century drew to a close, the Chaghatay ulus found itself at war with the three other Genghisid dynasties. The empires which the Ruler of the Universe had bequeathed to his sons were at each other’s throats.

      Genghis had been dead for more than a hundred years by the time of Temur’s birth, but the legacy of the Mongol conquests still hung over this land of desert, steppe and mountain. Many of the practicalities of daily life had undergone little transformation, and nomadism remained dominant in most of the regions Genghis had conquered. As John Joseph Saunders wrote in his classic account of the period, The History of the Mongol Conquests (1971), ‘Nomadic empires rose and fell with astonishing swiftness, but the essential features of the steppes remained unchanged for ages, and the description by Herodotus of the Scythians of the fifth century before Christ will apply, with trifling variations, to the Mongols of the thirteenth century after Christ, 1,700 years later.’

      For centuries the Mongols had driven their flocks and herds across the endless, treeless steppe, roaming from pasture to pasture in migrations whose timing was dictated by the seasons. Sheep and horses satisfied virtually all their needs. From sheep came the skins to fashion clothes, wool to make the gers they lived in, mutton and cheese to eat, milk to drink. Horses provided mounts for hunting and battle, as well as the powerfully intoxicating fermented mare’s milk, or kumis. Though their ways of life were utterly different, though both sides regarded each other with suspicion, born largely from the predatory instincts of the wandering horsemen, the nomads and the settled populations of the towns and cities of Central Asia came together from time to time to trade.

      Among the most prized products for the nomads were the metals with which to forge weapons. Tea, silks and spices were luxuries. Such trade predated Genghis by many centuries. Central Asia had existed as a crossroads between East and West ever since the Silk Road – 3,700 miles from China to the Mediterranean ports of Antioch and Alexandria via Samarkand – came into being around the beginning of the first century BC. By the time of the Mongols, there were at least another three major trade routes linking East to West. First there was the sea route from south China to the Persian Gulf. Another artery began in the lower Volga, clung closely to the Sir Darya and then headed east to western China. Finally, there was the northern route which from the Volga-Kama region cut through southern Siberia up to Lake Baikal, where it diverted south to Karakorum and Peking. Eastbound along these routes came furs and falcons, wool, gold, silver and precious stones. Westward went the porcelain, silks and herbs of China.

      If nomadism was one feature of life which remained virtually unchanged from the thirteenth to the fourteenth centuries, the military was another. Mongol men were all, almost by definition, soldiers, since any under the age of sixty were considered fit for service in the army. There was no concept of civilian men. In a desolate landscape, survival itself – primarily by the hunting of meat – demanded the same set of skills required on the battlefield. Military techniques were learnt from the earliest age. As soon as a boy could ride, he was well on his way to becoming a soldier. In the saddle, he learnt to master his horse absolutely and to manoeuvre it with the greatest finesse, to gauge the distance between himself and his quarry, and to shoot with deadly accuracy. It was the perfect training for a mounted archer, the backbone of Genghis’s army armed with the composite bow of horn, sinew and wood. As Gibbon remarked, ‘the amusements of the chase serve as a prelude to the conquest of an empire’.

      Genghis organised his army according to the traditional decimal system of the steppe: units of ten, one hundred, one thousand and ten thousand soldiers, a system which Temur retained. Soldiers were not paid other than in plunder from the enemies they defeated and the cities they stormed. Tribes which had once been hostile were deliberately divided into different units, thereby undermining tribal loyalties and creating a new force united in its loyalty to Genghis. This was in addition to his imperial guard of ten thousand, which functioned as the central administration of the empire. Temur would follow a similar strategy as he sought to weld together an army from the disparate tribes of Central Asia. There was continuity, too, in the tactics employed on the battlefield, particularly in the use of encirclement and the Mongols’ favourite device of feigned flight, which was the undoing of many an enemy.

      Religion was worn lightly by the Mongols. It consisted of the simple worship of Tengri, a holy
