Genghis Khan and the Making of the Modern World

by Jack Weatherford

In twenty-five years, the Mongol army subjugated more lands and people than the Romans had conquered in four hundred years. Genghis Khan, together with his sons and grandsons, conquered the most densely populated civilizations of the thirteenth century. Whether measured by the total number of people defeated, the sum of the countries annexed, or by the total area occupied, Genghis Khan conquered more than twice as much as any other man in history. The hooves of the Mongol warriors’ horses splashed in the waters of every river and lake from the Pacific Ocean to the Mediterranean Sea. At its zenith, the empire covered between 11 and 12 million contiguous square miles, an area about the size of the African continent and considerably larger than North America, including the United States, Canada, Mexico, Central America, and the islands of the Caribbean combined. It stretched from the snowy tundra of Siberia to the hot plains of India, from the rice paddies of Vietnam to the wheat fields of Hungary, and from Korea to the Balkans. The majority of people today live in countries conquered by the Mongols; on the modern map, Genghis Kahn’s conquests include thirty countries with well over 3 billion people. The most astonishing aspect of this achievement is that the entire Mongol tribe under him numbered around a million, smaller than the workforce of some modern corporations. From this million, he recruited his army, which was comprised of no more than one hundred thousand warriors...

In the end, Europe suffered the least yet acquired all the advantages of contact through merchants such as the Polo family of Venice and envoys exchanged between the Mongol khans and the popes and kings of Europe. The new technology, knowledge, and commercial wealth created the Renaissance in which Europe rediscovered some of its prior culture, but more importantly, absorbed the technology for printing, firearms, the compass, and the abacus from the East. As English scientist Roger Bacon observed in the thirteenth century, the Mongols succeeded not merely from martial superiority; rather, “they have succeeded by means of science.” Although the Mongols “are eager for war,” they have advanced so far because they “devote their leisure to the principles of philosophy.”

In the twelfth century, dozens of tribes and clans lived on the steppe in, as is characteristic of nomadic people, shifting combinations. Of all the steppe tribes, the Mongols’ closest relatives were Tatars and Khitan to the east, the Manchus yet farther to the east, and the Turkic tribes of central Asia to the west. These three ethnic groups shared a common cultural and linguistic heritage with some of the tribes of Siberia, where they possibly all originated. Located between the Tatars and the Turkic tribes with whom outsiders often confused them, the Mongols were sometimes known as Blue Turks or as Black Tatars. As speakers of Altaic languages, named for the Altai Mountain range in western Mongolia, their languages bore a distant similarity with Korean and Japanese, but none with Chinese or the other tonal languages of Asia.

The Tayichiud, with whom he shared a close kinship tie, had once put his family out to die and now appeared eager to kill him. This other family, which had no kinship tie to him, proved willing to risk their lives to help him. This episode seems to have instilled in him not only a distrust of higher-ranking people, but also the conviction that some people, even those outside his clan, could indeed be trusted as if they were family. In later life, he would judge others primarily by their actions toward him and not according to their kinship bonds, a revolutionary concept in steppe society.

Though the steppe tribes of his time changed sides at the least provocation and soldiers might desert their leaders, none of Temujin’s generals deserted him throughout his six decades as a warrior. In turn, Temujin never punished or harmed one of his generals. Among the great kings and conquerors of history, this record of fidelity is unique.

Temujin had defeated every tribe on the steppe and removed the threat of every aristocratic lineage by killing off their men and marrying their women to his sons and other followers. He chafed under the authority of anyone who stood above him. He killed Begter to rule over his family. He destroyed the Merkid because they took his wife. He killed off the Tatars who had killed his father and looked down on the Mongols as little more than steppe rats. He overthrew the nobles of his own Mongol people and eliminated one by one the higher-ranking Mongol clans of the Tayichiud and the Jurkin. When his own ally and father figure refused to allow a marriage between their respective families, Temujin destroyed him and his tribe. When the Naiman queen mocked the Mongols as her inferiors, he attacked the tribe, killed her husband, and gave her to one of his men as a wife. Finally, he killed Jamuka, one of the people whom he most loved in life, and thereby destroyed the aristocratic Jadaran clan.

Teb Tengeri was the last rival Genghis Khan had to face from the steppe tribes. What he could not control he had destroyed. He had neutralized the power of his own relatives, killed the lineages of aristocrats and all rival khans, abolished the old tribes, redistributed the people and, finally, allowed the most powerful shaman on the steppe to be killed.

The Chinese noted with surprise and disgust the ability of the Mongol warriors to survive on little food and water for long periods; according to one, the entire army could camp without a single puff of smoke since they needed no fires to cook. Compared to the Jurched soldiers, the Mongols were much healthier and stronger. The Mongols consumed a steady diet of meat, milk, yogurt, and other dairy products, and they fought men who lived on gruel made from various grains. The grain diet of the peasant warriors stunted their bones, rotted their teeth, and left them weak and prone to disease. In contrast, the poorest Mongol soldier ate mostly protein, thereby giving him strong teeth and bones. Unlike the Jurched soldiers, who were dependent on a heavy carbohydrate diet, the Mongols could more easily go a day or two without food.

the more captives Genghis Khan brought home, the more food and equipment he had to obtain to supply them. Novelties became necessities, and each caravan of cargo stimulated a craving for more. The more he conquered, the more he had to conquer.

In Genghis Khan’s conquest of central Asia, one group suffered the worst fate of those captured. The Mongol captors slaughtered the rich and powerful. Under the chivalrous rules of warfare as practiced in Europe and the Middle East during the Crusades, enemy aristocrats displayed superficial, and often pompous, respect for one another while freely slaughtering common soldiers. Rather than kill their aristocratic enemy on the battlefield, they preferred to capture him as a hostage whom they could ransom back to his family or country. The Mongols did not share this code. To the contrary, they sought to kill all the aristocrats as quickly as possible in order to prevent future wars against them, and Genghis Khan never accepted enemy aristocrats into his army and rarely into his service in any capacity.

Civilized rulers and religious leaders from China to Europe depended upon these gruesome displays to control their own people through fear and to discourage potential enemies through horror. When the Byzantine Christian emperor Basil defeated the Bulgarians in 1014, he had fifteen thousand Bulgarian war captives blinded. He left one man out of each hundred with one eye in order that he might lead the other ninety-nine homeward and thereby spread the terror. When the Christian Crusaders took cities such as Antioch in 1098 and Jerusalem in 1099, they slaughtered the Jews and Muslims without regard for age or gender, but merely because of their religion.

Within hours, the Mongols had completely destroyed the Georgian army and the small nation’s aristocracy. Subodei made the country a vassal state, the first in Europe, and it proved to be one of the most loyal and supportive Mongol vassals in the generations ahead.

The Christian cities of the plain managed to unite enough against the heathen invaders to send out their armies. Hastily assembled troops set out from all the small kingdoms and city-states of the area—Smolensk, Galich, Chernigov, Kiev, Volhynia, Kursk, Suzdal, and some of the Kipchak. Three of the armies—from Galich, Chernigov, and Kiev—came under the command of princes, all of whom were named Mstislav. The most impressive of the three Mstislavs was Prince Mstislav Romanovitch of Kiev, the largest and richest of all the cities, who arrived with the most impressive army, including his two sons-in-law.

Although the chroniclers of Armenia, Georgia, and the trading cities of ancient Russia recorded the appearance of the Mongols, they were totally mystified as to who these people were, and where they went when they left. The chroniclers interpreted their own defeat at the hands of these strangers as a punishment from God. Since the Mongols did not stay to occupy the land but continued on their trek back to Mongolia, the Europeans quickly forgot the Mongol victories and returned to their own squabbles. In the Christian interpretation, the Mongols had fulfilled God’s wish to chastise the people, so God sent them home again.

European knighthood never recovered from the blow of losing nearly one hundred thousand soldiers in Hungary and Poland, what the Europeans mourned as “the flower” of their knighthood and aristocracy. Walled cities and heavily armored knights were finished, and in the smoke and gunpowder of that Easter season of 1241, the Mongol triumph portended the coming total destruction of European feudalism and the Middle Ages.

Because of “the enormous wickedness of the Jews,” the Christians accused them of bringing the wrath of the Mongols on innocent Christians.

The capture of the unnamed Englishman coincided with the end of Mongol penetration into Europe. They had followed the grass steppes across central Asia, Russia, Ukraine, Poland, and Hungary; but where the pastures ended, the Mongols stopped. With five horses per warrior, they needed that pasture to function.

Disappointed with the material reward of their invasion and eager to show some profit, the Mongol officers struck a deal with the Italian merchants stationed in the Crimea. In exchange for large amounts of trade goods, the Mongols allowed the Italians to take many of their European prisoners, especially the young ones, to sell as slaves around the Mediterranean. This began a long and lucrative relationship between the Mongols and the merchants of Venice and Genoa, who set up trading posts in the Black Sea to tap this new market. The Italians supplied the Mongols with manufactured goods in return for the right to sell the Slavs in the Mediterranean markets.

While Ogodei reigned as Great Khan, for long periods of time he was too drunk to lead the empire, and he gradually conveyed administrative power to Toregene, the most capable, although not the senior, wife. At his death in 1241, she became the official regent. For the next ten years, until 1251, she and a small group of other women controlled the largest empire in world history. None of the women had been born a Mongol but had instead been married into the family from a conquered steppe tribe, and most of the women were Christians.

The pope’s letter chastised the Mongols for invading Europe, ordering the khan to “desist entirely from assaults of this kind and especially from the persecution of Christians.” He demanded an explanation from the khan “to make fully known to us . . . what moved you to destroy other nations and what your intentions are for the future.” The letter informed the khan that God had delegated all earthly power to the pope in Rome, who was the only person authorized by God to speak for Him.

Despite the extensive spiritual beliefs that the Mongols and Europeans shared in common, the opening relationship had been so negative and misguided that in future years, the entire base of shared religion would eventually erode. The Mongols continued for another generation to foster closer relations with Christian Europe, but in the end, they would have to abandon all such hope, and with it they would, in time, abandon Christianity entirely in favor of Buddhism and Islam.

From his court, Mongke Khan expanded the trials to a grand purge by sending out bands of inquisitors throughout the empire to question, convict, and punish anyone suspected of disloyalty to his branch of the family. The trials took place on a global scale from China and Mongolia in the east to Afghanistan in the south and Persia and Iraq in the west. Even the highest officials, such as the ruler of the Uighurs, were put to death, but the greatest damage was inflicted on the Golden Family itself.

No side seemed to convince the other of anything. Finally, as the effects of the alcohol became stronger, the Christians gave up trying to persuade anyone with logical arguments, and resorted to singing. The Muslims, who did not sing, responded by loudly reciting the Koran in an effort to drown out the Christians, and the Buddhists retreated into silent meditation. At the end of the debate, unable to convert or kill one another, they concluded the way most Mongol celebrations concluded, with everyone simply too drunk to continue.

The Mongol army had accomplished in a mere two years what the European Crusaders from the West and the Seljuk Turks from the East had failed to do in two centuries of sustained effort. They had conquered the heart of the Arab world. No other non-Muslim troops would conquer Baghdad or Iraq again until the arrival of the American and British forces in 2003.

In the six centuries since the birth of Islam, the religion had expanded greatly and lost control of a few border zones, but never had so much of the Muslim world fallen under the rule of pagans. The four decades from Genghis Khan’s attack on Bukhara until the fall of Baghdad and Damascus represented the lowest point in Muslim history. While the Crusaders had only managed to take a toehold in a few ports, the Mongols conquered every Muslim kingdom and city from the Indus River to the Mediterranean. They had conquered almost all of the Muslim lands in Asia; only the Arabian Peninsula and North Africa remained beyond their control.

An army of Mamluk slaves, mostly purchased from Italian merchants who brought them from the Kipchak and Slavic people of Russia and sold them to the sultan of Egypt, moved out from Egypt and encountered a Mongol detachment at Ayn al-Jalut, the Springs of Goliath, near the Sea of Galilee in what is today Israel. On the morning of September 3, 1260, a year after Mongke Khan’s death, the Mamluks defeated the Mongols. The empire had reached its western border.

That night, with all the invaders on their ships, a terrific fall storm blew in across the ocean. The Kamikaze, or Divine Wind, as it was later named by the Japanese, churned up the seas and shattered many of the hurriedly constructed boats against the rocks and shore. In an effort to escape, some thirteen thousand of the invaders died, most by drowning, in the deadly channel that separated them from the safe harbors of Korea. The greatest armada in history had turned into the greatest, but largely bloodless, massacre at sea.

The Mongols not only succeeded in building a unified Chinese state; at the same time, their influence exerted the same pressure on the small states around them. Early on, the Mongols had pushed for the unification of the culturally similar but constantly warring states of the Korean Peninsula into a unified nation. Similarly, in Southeast Asia, which remained beyond direct Mongol administration, the Mongol forces forged together new nations that laid a basis for Vietnam and Thailand. Prior to the Mongol era, the area that today composes the countries of Thailand, Laos, Vietnam, and Cambodia had been decisively Indian in culture and followed the architectural styles, religious practices, and mythology of Hindu India. The Mongols and the Chinese immigrants whom they had brought created a new hybrid culture that thereafter became known as Indo-Chinese.

Only a few generations earlier, Khubilai’s ancestors had used the hunt as the primary means of acquiring food. His great-grandfather Yesugei had been out hunting with his gyrfalcon when he saw the bride Hoelun, whom he seized to make his own wife. Khubilai’s grandfather Genghis Khan fed his family by hunting after his father’s death, and he had killed his half brother Begter in an argument ostensibly following a hunting quarrel about a bird and a fish. Later in life, Genghis Khan, with the aid of Subodei and other good hunters, adapted the extensive hunting strategies, techniques, and weapons to the task of warfare by treating his enemies as objects of prey to be trapped and stalked, and he thereby conquered his vast empire.

Whether in their policy of religious tolerance, devising a universal alphabet, maintaining relay stations, playing games, or printing almanacs, money, or astronomy charts, the rulers of the Mongol Empire displayed a persistent universalism. Because they had no system of their own to impose upon their subjects, they were willing to adopt and combine systems from everywhere. Without deep cultural preferences in these areas, the Mongols implemented pragmatic rather than ideological solutions. They searched for what worked best; and when they found it, they spread it to other countries. They did not have to worry whether their astronomy agreed with the precepts of the Bible, that their standards of writing followed the classical principles taught by the mandarins of China, or that Muslim imams disapproved of their printing and painting. The Mongols had the power, at least temporarily, to impose new international systems of technology, agriculture, and knowledge that superseded the predilections or prejudices of any single civilization; and in so doing, they broke the monopoly on thought exercised by local elites.

From the mixture of the absurd and the serious, the Soviets followed their own version of Mongol strategy in World War II. In a large-scale adaptation of the tactics Subodei used to defeat the Russians at the Kalka River in 1223, the Soviets lured the Germans ever deeper into Russia until they were hopelessly spread out over a large area, and then the Russians began to counterattack and pick them off one by one.
