The Mongol Empire (1206–1368)

Temujin, having united the nomadic tribes of the Mongolian plateau through a combination of military conquest, strategic alliances, and the implementation of a meritocratic system, was proclaimed Genghis Khan (Universal Ruler) at a kurultai (grand council) on the banks of the Onon River. He established the Mongol Empire, introduced a legal code known as the Great Yassa, and organized the Mongol army into the highly disciplined decimal system of arbans (10s), zuuns (100s), myangans (1,000s), and tumens (10,000s).

Genghis Khan launched a massive invasion of the Jin dynasty of northern China, which controlled approximately 50 million people. The Mongol army, using superior mobility, innovative tactics including feigned retreats, and captured Chinese siege technology, overwhelmed the Jin forces. The invasion marked the beginning of the Mongol conquest of China and demonstrated the Mongol army's ability to defeat large, settled civilizations with sophisticated military organizations.

Location: Northern China

Mongol forces captured and sacked Zhongdu (Central Capital), the Jin dynasty's principal city, after a year-long siege. The city, which had a population of over one million, was burned to the ground. The Mongols' use of Chinese siege engineers and their willingness to adapt to settled warfare tactics proved decisive. The fall of Zhongdu forced the Jin capital to move south to Kaifeng and established Mongol dominance in northern China.

After the Khwarazmian Shah Muhammad II murdered a Mongol trade delegation and the envoys Genghis Khan sent to demand restitution, the Mongol ruler launched a full-scale invasion of the Khwarazmian Empire, which stretched from modern-day Iran to Kazakhstan. The Mongol campaign, involving up to 200,000 soldiers, systematically destroyed the empire's major cities including Samarkand, Bukhara, and Urgench. The conquest of Khwarazm brought the Mongols into contact with the Islamic world and demonstrated Genghis Khan's willingness to wage total war against those who defied him.

Genghis Khan died during the final campaign against the Western Xia dynasty, at approximately 65 years of age. His death was kept secret by his army until the Western Xia capital was captured and destroyed. The empire was divided among his four sons by his chief wife Borte: Jochi (later Batu), Chagatai, Ogedei, and Tolui. Ogedei was elected as the second Great Khan, continuing the expansion of the empire. Genghis Khan's tomb remains undiscovered, in accordance with his burial wishes.

A Mongol army under Batu Khan and Subutai defeated the Hungarian army of King Bela IV at the Battle of Mohi, while another Mongol force destroyed a Polish army at the Battle of Legnica. Within two years, the Mongols had conquered much of Eastern Europe, including Poland, Hungary, and parts of the Balkans. The campaigns, which demonstrated the Mongols' ability to defeat European armies, were halted only by the death of Great Khan Ogedei, which required Batu to return to Mongolia for the election of a successor.

A Mongol army led by Hulagu Khan, grandson of Genghis Khan, captured Baghdad after a short siege, ending the 500-year Abbasid Caliphate. The city, then the intellectual and cultural center of the Islamic world, was sacked and its population massacred — estimates of the death toll range from tens of thousands to over one million. The destruction of the irrigation systems in the Tigris-Euphrates valley and the burning of the House of Wisdom's libraries marked a turning point in Islamic history.

The Mamluk Sultanate of Egypt defeated a Mongol army at the Battle of Ain Jalut, marking the first time a Mongol army had been decisively defeated in open battle. The Mamluks, using a feigned retreat tactic that turned the Mongols' own strategy against them, killed the Mongol general Kitbuqa and halted the Mongol advance into North Africa and the Levant. The battle established the Mamluks as the dominant power in the eastern Mediterranean and set the southern boundary of the Mongol Empire.

Kublai Khan, grandson of Genghis Khan, proclaimed the Yuan dynasty, formally establishing Mongol rule over all of China. The Yuan dynasty, with its capital at Khanbaliq (present-day Beijing), was the first foreign dynasty to rule all of China. Kublai adopted Chinese administrative practices while maintaining Mongol military and cultural traditions. The Yuan period saw advances in trade, science, and culture, including Marco Polo's travels to China, but was also marked by heavy taxation, paper money inflation, and social stratification.

In November 1274, Kublai Khan launched an invasion of Japan with a combined Mongol and Korean fleet estimated at 500-900 ships carrying 30,000-40,000 troops. The invaders landed at Hakata Bay on Kyushu, but a typhoon destroyed much of the fleet, forcing the Mongols to withdraw. The Japanese defenders, though outnumbered and out-teched, fought fiercely, and the typhoon — later called kamikaze (divine wind) — was interpreted as divine protection of Japan.

In 1281, Kublai Khan launched a second, much larger invasion of Japan with a fleet estimated at 4,400 ships and 140,000 soldiers — the largest naval invasion in history before the Normandy landings. The Japanese had built coastal defenses, and the invasion bogged down in fighting at Hakata Bay. A massive typhoon struck in August, destroying the Mongol fleet and killing tens of thousands of invaders. The second typhoon cemented the legend of the kamikaze and confirmed Japan's independence from Mongol rule.

From 1271 to 1295, the Venetian merchant Marco Polo traveled overland to the court of Kublai Khan in China and remained there for 17 years, serving as an official in the Mongol administration. His account of his travels, The Description of the World (Il Milione), introduced Europeans to the sophistication, wealth, and scale of Chinese civilization. The book became one of the most influential travel narratives in history, inspiring Christopher Columbus and other European explorers who sought to establish direct contact with the riches of the East.

The Yuan dynasty collapsed as the Red Turban Rebellion, a peasant uprising fueled by famine, flooding, and heavy taxation, overwhelmed Mongol forces. Zhu Yuanzhang, a former Buddhist monk and Red Turban leader, captured Khanbaliq (Beijing) and proclaimed the Ming dynasty, ending Mongol rule over China. The Mongol court retreated to the Mongolian plateau, where the Northern Yuan dynasty continued for several more centuries. The fall of the Yuan marked the end of the unified Mongol Empire, though Mongol successor states survived in Central Asia, Persia, and Russia.
