Marco Polo Describes the Mongols: 13th Century Primary Source

After Genghis Khan's death, the Mongol Empire split into four khanates: Yuan (China), Chagatai (Central Asia), Ilkhanate (Persia), and Golden Horde (Russia/Europe). The Golden Horde further divided into White and Blue Hordes. The White Horde converted to Islam under Öz Beg Khan in 1331, though full conversion took 100 years. The Yuan Dynasty was already declining by 1337, weakened by the Red Turban Rebellion and natural disasters. The Delhi Sultanate faced internal fragmentation, while the Ilkhanate collapsed after the Black Death killed its leadership in 1335. These events shaped the geopolitical landscape of Eurasia at the game's start date.

The Mongol Empire, founded by Genghis Khan in 1206, was the largest contiguous land empire in history, stretching from Japan to the Mediterranean and from Siberia to the Persian Gulf. After Genghis Khan's death in 1227, the empire fragmented into four major khanates: the Golden Horde, the Ilkhanate, the Chagatai Khanate, and the Yuan Dynasty. Internal succession disputes, particularly between Hulagu Khan and Berke Khan, weakened the empire's unity. The Mongol expansion into Europe ended with their defeat at Ain Jalut in 1260, and the empire's decline accelerated as these khanates became increasingly independent. The Yuan Dynasty in China was eventually overthrown by the Ming Dynasty in 1368, marking the complete collapse of the Mongol Empire. Modern Mongolia, once the heart of this vast empire, is now a small landlocked country between China and Russia, with a population of approximately 3.3 million people.

The Mongol Empire controlled virtually all of Asia and extended into Europe, with only Korea, India, and Japan remaining unconquered. The empire stretched from the Pacific Ocean to the Danube River in Central Europe, making it the largest contiguous land empire in history. Genghis Khan divided his empire among his four sons to facilitate conquest of different regions: Jochi received Central Asia and Eastern Europe, Chagatai received Central Asia, Ögedei was designated as successor, and Tolui received the Mongol homeland. This division was necessary because the empire was too large to be governed by a single ruler. The Mongol Empire was divided into five major khanates: the Golden Horde (Jochi's descendants), the Chagatai Khanate (Chagatai's descendants), the Ilkhanate (Hulagu's descendants), the Yuan Dynasty (Tolui's descendants), and the Khanate of the White Horde. These five khanates effectively partitioned the world, with each ruling over different regions. The Golden Horde, established by Jochi's son Batu, controlled a vast territory stretching from the Danube River in Eastern Europe to the borders of Central Asia, including modern-day Ukraine, Russia, Kazakhstan, and other Central Asian states. The Golden Horde maintained its power for approximately 300 years, far longer than the Yuan Dynasty.

Genghis Khan, who founded the world's second-largest empire and killed nearly 10 million people, established a family tree where his four sons divided his vast Mongol Empire into four khanates: Batu Khan received the Golden Horde in Russia and Central Asia, Chagatai Khan controlled lands between Persia and Mongolia (whose descendants later founded the Mughal Empire), Ogedei Khan became the second Great Khan and expanded the empire to Poland, and Tolui Khan received central Mongolia and western China; this division occurred after Genghis Khan's death in 1227, when he was buried in an unknown location as per his wishes, and his legacy continued through his descendants who ruled until the Ming dynasty took over the Yuan capital in 1370.

Following succession struggles after Genghis Khan's death, Kublai Khan defeated rivals and divided the empire into four Khanates: Yuan Dynasty (China/Korea), Chagatai Khanate (Afghanistan), Golden Horde (Russia/Hungary), and Ilkhanate (Persia). Kublai, educated in Chinese court traditions, established the Yuan Dynasty in 1271. However, his civilized approach clashed with traditionalist Mongol warriors who valued martial culture over scholarly pursuits, creating internal tensions that would contribute to the empire's eventual decline.

There is a paradox in the Mongol Empire that Marco Polo understood better than almost any European of his era and that later history took a long time to recognize. The same conquerors who destroyed some of the largest and most advanced cities of the medieval world also created the conditions for commerce between Europe and Asia to reach its historical maximum. The Mongols killed millions of people. They destroyed Baghdad, which in 1258 was the largest and intellectually most active city in the Islamic world. They razed cities in Persia, Central Asia, and China. The Persian historian Juvaini wrote that when the Mongols arrived at a city it was as if it had never existed, not even a blade of grass where it had once grown. And yet, once conquest ended and initial terror passed, the Mongols were surprisingly pragmatic governors. They did not care about the religion of their subjects, they did not care about the language they spoke, they did not care about local culture. The only thing that mattered to them was order, obedience, and especially the payment of taxes. This pragmatism created something that had not existed before, a zone of peace and commerce that extended from the Eastern Mediterranean to the Pacific. The historians call it the Pax Mongolica, the Mongol Peace. During approximately 100 years, along the 11th century and early 14th century, a merchant could travel from Europe to China under the protection of Mongol authority, with documents issued by the Khan guaranteeing security and access to the transportation and accommodation systems of the empire. Marco Polo traveled in that world. The Paizi that Khan gave him were literally the passport of that commercial peace.

In the 13th century, Mongol armies created the largest conquest empire in history, stretching from Poland to the Sea of Japan. Beyond their reputation as conquerors, the Mongols were sophisticated and often generous rulers who pacified the Silk Road. The Pax Mongolica—the Mongol-enforced peace—ended banditry that had plagued traders for centuries. Bandits feared Mongol soldiers so much that they avoided trade routes entirely. This unprecedented security allowed merchants, missionaries, and diplomats to travel safely between China and Europe for the first time in world history. The Mongols' reputation created safe passage, connecting China with Europe and the Near East in ways that profoundly influenced European civilization's development. Venetian and Genoese merchants reaped enormous profits, funding magnificent art and architecture, while Marco Polo's accounts tantalized Europe with tales of China's immense wealth and advanced civilization.

The Mongol Empire controlled territory from the Pacific to Eastern Europe, encompassing dozens of languages, religions, and legal systems. Unlike most conquerors who forced their religion on subjects, the Mongols were remarkably tolerant. They allowed people to practice Christianity, Islam, Buddhism, or any other faith as long as they paid taxes and prayed for the Khan. This policy was unusual for the time, when most conquerors imposed their religion on conquered peoples. The Mongols valued loyalty and tax revenue above religious uniformity. They built a network of roads and relay stations across their entire empire. Fresh horses were stationed every 50 miles, allowing messengers to travel thousands of miles in weeks. A message could travel from China to Persia in less than two weeks—faster than anything in the world at the time. They created special passports called 'Paiza,' metal tablets that served as access cards. Anyone showing a Paiza at any checkpoint could pass without interference. Bandits were hunted by Mongol patrols, making routes safer than they had been for centuries. For centuries, the Silk Road had been a nightmare for travelers—filled with bandits, border taxes, and local warlords. The Mongols changed everything by unifying the entire route under one power. For the first time in history, a single authority controlled the entire path from the Pacific to Europe. Merchants who had previously had to bribe dozens of hostile kingdoms could now travel safely under Mongol protection. Trade exploded, with Chinese silk flowing west and Persian spices flowing east in quantities exceeding previous records. The Mongols did more than move goods—they facilitated the exchange of ideas and technology. Printing technology spread from China. Medical knowledge moved between civilizations. Gunpowder, originally a Chinese invention, began its journey to Europe. The world became smaller and more connected. One traveler noted that a journey that previously took two years now took only four months. This era is called the Pax Mongolica (Latin for 'Mongol Peace'). It represents the first true globalization in human history—a period when a single power controlled the entire world from coast to coast, enabling unprecedented exchange of goods, people, and ideas.

The Mongol Empire, created by pastoral nomads from Central Asia in the 13th century and conquering from Poland to Japan, established Pax Mongolica—a period of peace that transformed Silk Road trade. Under Mongol protection, traders faced no banditry, and Europeans traveled east bringing back Asian goods like cloth and spices. This unprecedented connection between China and Europe profoundly affected European civilization, funding art and architecture in Italian cities like Venice and Genoa, whose merchants established trading posts throughout Eurasia.

One of the parties threatening the tracks in the far east would later grow in power and would return the road to its past glories: the Mongols. Under their first emperor Genghis Khan, they took a campaign of conquest and terror that swept across most of Asia, reaching Eastern Europe. After the death of Genghis in 1227, there followed a period of stability known as the Pax Mongolica, in which almost the entirety of the Silk Road fell under the control of a single entity. Safety from bandits and less taxation revived trade once again. The Mongols also improved infrastructure and communication along the Silk Road by creating an efficient postal relay system and through religious freedom, they encouraged once again the exchange of new ideas and philosophies.

Venice in the 13th century was a powerful mercantile republic dominating Mediterranean trade. Originally focused on salt and fishing, Venice evolved into a major commercial hub distributing goods from the North and East through Constantinople. The Venetian political model emphasized diplomacy and international relations through a network of consulates. Marco Polo participated in only the second of three major journeys to Asia, traveling with his father Niccolò and uncle Maffeo, who had pioneered the route to the Mongol Empire. This second journey included stops in Armenia (where he noted Noah's Ark on Mount Ararat), Georgia, and Persia, serving both commercial and religious purposes.

In the 13th century, Venice was a machine built for trade, measuring power by commerce rather than castles and armies. Its merchants moved across the Mediterranean toward Constantinople, Alexandria, and the Black Sea, trading silk, spices, glass, and information. Stories were survival, not entertainment. Marco Polo was born around 1254 into a merchant family. His father left for the east when Marco was young and did not return for nearly a decade. Growing up without his father, surrounded by sailors telling impossible stories and merchants returning with strange objects, Marco developed a hunger for truth and distance that shaped his future journey.

Marco Polo returned to Venice after 24 years of absence, having traveled through entire continents and territories most Europeans only knew by name. He crossed deserts without roads, mountains where thin air made breathing difficult, and lived within an empire vastly larger than any Western kingdom. When he began describing what he saw, the reaction was not admiration but distrust. His listeners were Mediterranean merchants accustomed to trade with Constantinople and Alexandria, but he described cities larger than entire European regions, administered by salaried officials according to precise rules. Among his most surprising claims was the existence of paper money issued by the state and accepted without discussion throughout the empire. Following the war between Venice and Genoa, Polo was captured during a naval battle and imprisoned. There he met Rustichello da Pisa, a writer accustomed to collecting stories of knights and distant lands. Night after night, Polo recounted his experience, no longer as an occasional story but as a complete and ordered narrative. From these conversations emerged a manuscript destined to spread throughout Europe, copied and translated into numerous versions. To understand Marco Polo's story, one must start from the context of his birth, because his journey was not the result of an impulse but the direct consequence of the economic and social environment of 10th-century Venice. In 1200, the city was one of the main commercial powers of the Mediterranean. Its geographical position between continental Europe and eastern maritime routes made it a constant meeting point between different cultures. Ships from Byzantium, the Levant, and North Africa unloaded goods that were then redistributed toward central Europe. Spices, silks, precious stones, and rare metals formed the basis of the city's wealth, and much of the population depended directly or indirectly on commerce. Venetian merchants were not simply sellers but entrepreneurs who invested capital in long-duration expeditions, often sharing risks among multiple partners. Traveling for years away from home was considered normal. Many young people grew up preparing to conduct negotiations in different languages, coexist with different religious customs, and adapt to non-European political systems. Marco was born around 1254 within this commercial environment. His family belonged to the merchant class and operated on longer routes than average. His father Niccolò Polo and uncle Matteo Polo had already established commercial contacts in the Black Sea and Central Asian regions, territories that for most Europeans were remote and poorly known. During one of their journeys, they decided to continue beyond their usual commercial destinations, following caravan routes into the interior of the Asian continent. They crossed territories controlled by Turkic-Mongol populations and after years of movement reached the court of the Mongol sovereign Kublai Khan. The meeting was not only diplomatic but also practical. The emperor, interested in Western knowledge, entrusted them with a formal request destined for the Pope. When Niccolò returned to Venice, Marco was already an adolescent who had spent his childhood without his father. The stay in Venice was brief. A new expedition was prepared, and Niccolò decided to take his son with him, probably to definitively insert him into the family's commercial activity. In 1271, Marco Polo left Venice together with his father and uncle. He did not depart as an explorer in the modern sense, but as a young merchant in training destined to learn the trade along the great Eurasian routes. The departure of the Polos in 1271 did not occur as an organized expedition with a predefined itinerary, but as a succession of stops along existing commercial networks. In the Middle Ages, there was no single Silk Road, but rather a system of paths that changed according to political conditions, security, and seasons. After leaving Venice, the travelers reached the Eastern Mediterranean, where European ships could dock at ports controlled by Christian or Muslim powers. From there, the journey continued by land following routes frequented by Arab, Persian, and Central Asian merchants. The rhythm of movement did not depend on individual will but on the availability of organized caravans, indispensable for crossing territories that were little safe. Caravans represented true temporary communities, including merchants, local guides, pack animals, translators, and armed guards. Traveling alone would have been too dangerous. Beyond the risk of bandits, there were unstable borders and areas completely lacking supply points. The union of multiple groups allowed sharing of water, information, and protection. Crossing the Iranian Plateau, the Polos entered regions characterized by great distances between inhabited centers. Here, travel organization was essential. Stops were established based on the position of wells and caravanserai cities. Poor planning could mean loss of pack animals and therefore merchandise, compromising the entire expedition. Subsequently, they reached mountainous regions of Central Asia. Overcoming the reliefs required long times and adaptation to climatic conditions. At high altitudes, oxygen decreased and animals struggled to transport loads. The paths were narrow and often exposed to landslides or sudden weather variations. After the mountains began the desert regions. The desert was not a single uniform space but a series of arid environments alternated with oases. Caravans traveled for days without encountering permanent settlements, orienting themselves through natural reference points and knowledge orally transmitted by local guides. Stops were rigidly programmed to avoid excessive consumption of water reserves. The most demanding stretch was the crossing of the great Gobi Desert. Here, the distance between inhabited areas increased further and the landscape offered few visual references. Travelers often moved at night or during the least hot hours to reduce animal effort and limit dehydration. The overall journey lasted several years, not for slowness but for logistical necessity. Seasons influenced movements and sometimes it was necessary to remain for months in a city waiting for favorable conditions or the departure of a new caravan. Around 1275, after a long progressive journey through Inner Asia, the Polos finally reached territories administered directly by Kublai Khan's court. Their arrival did not represent the end of an improvised adventure but the completion of a complex transfer made possible by the commercial and political infrastructure of the Mongol Eurasian Empire. When the Polos arrived in territories governed by the Mongols, they found a political reality very different from the European one. It was not a succession of neighboring kingdoms often at war with each other, but a space administered by a single supreme authority derived from the conquests begun by Genghis Khan and continued by his successors, including Kublai Khan. The empire was not uniform from a cultural point of view, including Mongol nomadic populations, densely populated Chinese cities, Islamic commercial centers, and agricultural regions of different traditions. Its stability depended on the capacity to integrate local systems rather than completely replacing them. A fundamental element was control of com

Venice emerged as the dominant trading power of the medieval Mediterranean through its strategic position on the Silk Road. The city became the largest market in the region, with families like the Polos trading silk, spices, and precious stones transported by caravans. Marco Polo's journey began in 1271 when he accompanied his father and uncle on what would become a 27-year adventure. Upon returning home, they were refused entry because they had aged dramatically—wearing Mongol cloaks and heavy beards after decades abroad. Captured during a naval battle against Genoa, Polo dictated his famous book while imprisoned. The Venetians nicknamed him 'Il Milion' (the Millions Man) because he described everything in enormous numbers—thousands of armies, soldiers, and horses—that no one believed. His book, existing in over 100 versions, inspired explorers like Columbus and established Venice as a center of geographic knowledge.

Venice was a major mercantile power built on the Adriatic lagoon, deriving power from commercial contracts and trade routes rather than territorial conquest. Marco Polo's father Niccolò and uncle Maffeo were experienced merchants who had traveled to the East before his birth. Marco grew up hearing stories of distant lands, powerful rulers, and exotic peoples, which shaped his worldview. His practical education in arithmetic, merchandise valuation, and observation prepared him for commercial life. The city's cosmopolitan environment with merchants from Arab, Jewish, and Byzantine backgrounds exposed him to multiple cultures daily, reducing his discomfort with the unfamiliar.
