As a favorite of the Yongle Emperor, whose usurpation he assisted, he rose to the top of the imperial hierarchy and served as commander of the southern capital Nanjing (the capital was later moved to Beijing by the Yongle Emperor). These voyages were long neglected in official Chinese histories but have become well known in China and abroad since the publication of Liang Qichao's Biography of Our Homeland's Great Navigator, Zheng He in 1904. A trilingual stele left by the navigator was discovered on the island of Sri Lanka shortly thereafter.
