Zheng He

The Chinese Muslim admiral led seven extraordinary naval expeditions for the Ming Dynasty between 1405 and 1433, commanding fleets of up to 317 ships and 28,000 men — the largest armadas in pre-modern history. Zheng He's voyages reached Southeast Asia, India, the Persian Gulf, and the East African coast, establishing tributary relationships and trading networks that demonstrated China's maritime supremacy nearly a century before European ships reached those same shores. His treasure ships, some reportedly over 400 feet long, dwarfed anything being built in Europe at the time. The decision by later Ming emperors to abandon maritime expansion remains one of history's most consequential policy reversals.
