Zheng He was born around 1371 in Yunnan, China, into a Muslim family. His birth name was Ma He. During the conflicts surrounding the Ming conquest of Yunnan, he was captured as a young boy and later entered the service of the Ming court.
He eventually became a trusted official of the Yongle Emperor. His abilities and loyalty helped him rise to a position of considerable influence within the imperial administration.
Beginning in 1405, Zheng He was appointed to lead a series of major naval expeditions. These voyages travelled through the South China Sea and across the Indian Ocean.
The expeditions visited numerous ports and kingdoms, establishing diplomatic relationships, conducting trade and demonstrating the power of the Ming court.
Zheng He's voyages continued for almost three decades, making him one of the most notable maritime figures of the medieval world.
