The Collapse of the Mongol Empire and its Immediate Aftermath

Key Insight

The Black Death served as the decisive catalyst for the collapse of the vast Mongol Empire, fundamentally disrupting the intricate network of commerce, communication, and information flow upon which its unity depended. The plague not only ravaged populations but also severed the critical connections between various Mongol-ruled regions. Mongols in Persia and Russia found themselves cut off from essential goods and workshops in China and Mongolia, respectively, while the Golden Family in China could no longer procure resources from Russia or Persia. This mutual isolation caused the interlocking system of ownership and trade to disintegrate entirely. The widespread devastation and demoralization of the living population, combined with the cessation of trade and tribute, deprived the Mongol Golden Family of its primary financial and logistical support, fatally weakening its authority and ability to govern. For nearly a century, the Mongols had successfully leveraged shared material interests to bridge political divisions and maintain a unified cultural and commercial empire despite sacrificing political unity. With the plague's onslaught, however, the center could no longer hold, and the complex imperial system irreversibly broke down.

As foreign conquerors, the Mongols had been largely tolerated by their vastly more numerous subjects, often outnumbering them by as much as 1000 to 1, primarily because they ensured a continuous flow of trade goods, even as their military strength waned. In the plague's aftermath, deprived of both the vital trade and the prospect of military reinforcements from other Mongol branches, each segment of the Golden Family of Genghis Khan was forced to independently secure its power and legitimacy within increasingly volatile and potentially hostile environments. This led to significant cultural assimilation: Mongols began intermarrying with their subjects and consciously adopting their languages, religions, and cultural practices. Consequently, Mongol authorities purged remaining elements of shamanism, Buddhism, and Christianity from their families, strengthening their commitment to Islam, which was the predominant religion among their subjects. In the case of the Golden Horde in Russia, Islam became the religion of the powerful Turkic army that helped maintain the family's rule. However, this alignment with specific religious factions within subject populations exacerbated rifts among the Mongol royal lineages, leading to internal conflicts such as the Golden Horde's alliance with Egypt against the Mongol Ilkhanate before the Ilkhanate rulers themselves converted to Islam. The universal principles that had once underpinned Genghis Khan's empire gradually vanished, replaced by shifting political and religious allegiances, sometimes even oscillating between Sunni and Shiite Islam as suited the immediate political context, as seen during Oljeitu's reign which saw persecution of minority groups like Buddhists and Jews.

In China, Khubilai Khan's successors failed to emulate his successful integration into Chinese culture. Instead, they increased repression and isolated themselves, often driven by paranoia and rumors, such as royal court dreams where Genghis Khan demanded stringent measures against the Chinese. Mongol authorities intensified their foreign identity, separating themselves from Chinese language, religion, and culture, and even forbidding intermarriage. Extreme measures included confiscating Chinese weapons and iron agricultural tools, limiting knife use, banning horses for Chinese, and stopping Chinese opera, storytelling, and public gatherings to prevent secret messages. This mounting paranoia led to Chinese discontent and rumors of mass extermination plans. The Mongols further alienated the Chinese by abandoning their traditional evenhanded religious approach, granting increased favor to Tibetan Buddhism, which strongly contrasted with Confucian ideals. Tibetan Buddhist monks, often armed, acquired a reputation for abusing locals obligated to support them along trade routes. While the Mongols later overturned laws proposing severe mutilations for harming monks as incompatible with their own principles, the damage to relations was done. As the khans retreated into Tibetan monks' spirituality, focusing on individual spiritual merit through acts like freeing prisoners (which became a business), and engaging in Tantric rites involving sexual acts and rituals, Chinese distrust deepened, with suspicions of human sacrifices to prolong the khan's life. Meanwhile, outside the Forbidden City walls, the Mongolian monetary system collapsed. By 1356, paper currency became effectively worthless due to unchecked inflation and a loss of confidence. The rapid collapses in Persia (1335) and China (1368) saw the Ilkhanate Mongols disappearing, either killed or absorbed, and the Great Khan Togoon Tumur fleeing with 60000 Mongols, leaving 400000 to be captured, killed, or absorbed by Ming rebels. Those who returned to Mongolia reverted to nomadic pastoralism. The Golden Horde in Russia fragmented, declining in power over centuries, leading to the amalgamation of Mongols and Turkic allies into distinct Turco-Mongol ethnic groups.
