The admiral who helmed these voyages was the unlikeliest person to lead such an expedition—a Muslim eunuch of Mongol origin called Zheng He who began life in landlocked Yunnan! He had been captured as a young boy when the Ming were evicting Mongols from the province and was castrated before being presented as a servant to a prince. A bond of trust must have developed between the two boys because when the prince became Emperor Yongle, he put the young eunuch in charge of the Treasure Fleet.
