The Treasure Fleets of Zheng He, Which Sailed to Africa and Back — and Were Then Deliberately Forgotten

Zheng He was born Ma He, a Muslim boy of Mongol-era colonial stock in Yunnan, captured at about ten by the conquering Ming army, castrated, and placed in princely service — where his talent carried him to the side of the prince who usurped the throne as the Yongle Emperor. Yongle, needing legitimacy and grandeur, ordered the ocean put on notice: a fleet beyond precedent, built at Nanjing’s Longjiang yards, with his towering eunuch confidant in command.

The treasure fleets were floating statecraft. The first voyage (1405) counted by the chronicles over 250 ships and some 27,000 personnel — sailors, soldiers, interpreters, physicians, astrologers — around a core of giant nine-masted “treasure ships” whose recorded dimensions (140 metres by the Ming History) modern naval architects discount to perhaps 60-70 — which would still make them the largest wooden ships ever built. Across seven voyages (1405-1433) the fleets ran the maritime silk road in force: Champa, Java, Malacca (raised from village to emporium under Ming patronage), Ceylon — where a hostile king was defeated and shipped to Nanjing — Calicut, Hormuz, Aden, Mecca’s port of Jedda, and down the Swahili coast to Mogadishu and Malindi.

They fought pirates (the pirate-king Chen Zuyi was crushed at Palembang and executed), installed and deposed rulers, and carried home tribute embassies by the dozen. The signature cargo arrived in 1414: a giraffe, sent via Bengal from Malindi, received at court as the qilin — the unicorn-like auspicious beast of Confucian prophecy — to the emperor’s studied modesty and the court painters’ lasting delight.

The stopping

Then China — uniquely among powers presented with the ocean — declined it. Yongle’s successors faced the ledger: the voyages were ruinously expensive prestige in a state whose real threats rode horses on the northern frontier and whose Confucian bureaucracy despised both commerce and the eunuch establishment that ran the fleets. After a final voyage (1431-33), on which Zheng He died at sea, the expeditions ceased; ocean-going construction was curtailed, private sea trade banned for long stretches, and the fleet’s records vanished from the archives — by stubborn (if debated) tradition, deliberately destroyed by the war ministry official Liu Daxia as records of a “wasteful extravagance.” The greatest navy on Earth was, within decades, administratively erased.

The vacated ocean

Sixty years after the last treasure fleet came home, Vasco da Gama entered the Indian Ocean with four small ships and found rich sea lanes patrolled by no great power — at Malindi, of all ports, he hired the pilot who showed him the way to India. The counterfactual has haunted historians ever since. Zheng He’s memory, kept alive for centuries mainly in Southeast Asian temples where the admiral is worshipped as a deity, has lately been restored to official Chinese favour — patron, retroactively, of every maritime ambition his empire once cancelled.
