Zheng He — Ming Admiral and Commander of the Treasure Voyages
A Muslim eunuch from Yunnan who rose to become the Ming dynasty's grand admiral, commanding seven state expeditions across the Indian Ocean between 1405 and 1433. His fleets projected Chinese power from Southeast Asia to East Africa decades before European oceanic expansion, before the Ming court withdrew from the seas.
Events
Capture and Entry into the Prince of Yan's Household
Ming armies conquered Yunnan, then held by a Mongol prince loyal to the Northern Yuan. The boy Ma He, born around 1371 to a Muslim family, was captured, castrated, and placed in the household of Zhu Di, the Prince of Yan, in Beiping (modern Beijing). He received an education unusual for a eunuch and grew into a trusted servant and soldier on the northern frontier.
Location: Yunnan, China
The Jingnan Campaign and the Zheng Surname
Ma He distinguished himself in the Jingnan campaign, the civil war in which Zhu Di overthrew the Jianwen Emperor and took the throne as the Yongle Emperor. Rewarded with the surname Zheng, he rose to the top of the imperial hierarchy and was made commander of the southern capital Nanjing.
Location: Nanjing, China
First Treasure Voyage to Calicut
The Yongle Emperor commissioned the first of seven treasure voyages. The fleet — by traditional accounts over 300 ships and some 27,000 men — sailed via Southeast Asia to Calicut in India. The expeditions combined diplomacy, trade, and naval power, establishing a Ming presence across the Indian Ocean that historians have described as a new militaristic force in the region.
Location: Nanjing, China
Conflict in Ceylon
During the third voyage (1409-1411), Zheng He's forces clashed with the ruler Alekeshvara, who was captured and taken to Nanjing. The episode demonstrated the fleet's capacity for armed coercion alongside its diplomatic missions, and voyages continued on a larger scale with the fourth expedition (1413-1415) reaching Hormuz.
Location: Kotte, Ceylon (modern Sri Lanka)
The Giraffe and the Fifth Voyage to East Africa
Fleets on the fourth and fifth voyages (1413-1419) reached the Swahili coast, with envoys from Malindi and other states traveling to China. A giraffe presented at the Ming court in 1414 was celebrated as an auspicious qilin. The voyages extended Chinese state-controlled trade networks from China to Africa, an unprecedented reach for any naval power of the era.
Location: Malindi, East African coast
Suspension After the Yongle Emperor's Death
The Yongle Emperor died and his successor the Hongxi Emperor halted the expensive oceanic expeditions, favoring fiscal retrenchment and northern defense. Zheng He remained in imperial service as commander of Nanjing, and the great fleet was laid up.
Location: Nanjing, China
The Seventh and Final Voyage
The Xuande Emperor revived the voyages for one final expedition (1430-1433), reaching Hormuz and the East African coast again. Zheng He died in 1433, at sea or shortly after the fleet's return. Traditional accounts describe his largest treasure ships as almost twice as long as any wooden ship ever recorded, though modern scholars debate the exact dimensions.
Location: Indian Ocean
Ming Withdrawal from the Seas
After the final voyage, the Ming court ended state oceanic expeditions and restricted private maritime trade. Later officials destroyed or neglected much of the voyage records. The withdrawal closed an era in which China had been the dominant naval power in Asia, decades before Portuguese caravels entered the Indian Ocean.

Legacy — Sam Po Kong and Global Memory
Zheng He is remembered in Southeast Asia through temples such as Sam Po Kong in Semarang, Indonesia, where he is venerated under the name Sam Po. In the modern era his voyages have been cited both in China as evidence of a peaceful maritime tradition and by historians as a counterpoint to European colonial expansion — a dual legacy that reflects the expeditions' blend of diplomacy and coercion.
