The Yongle Emperor issued imperial orders that initiated large-scale shipbuilding for an oceangoing armada, laying the material base for the state-directed treasure voyages and their associated tributary trade.
The court granted Ma He the surname Zheng (becoming Zheng He), formalizing the identity under which he would command the maritime expeditions on behalf of the Yongle Emperor.
After departure, the fleet reached Liujiagang, where crews performed rituals to Mazu, reflecting the integration of state maritime policy with sailors’ religious practices and the practical realities of long-distance navigation.
Zheng He’s fleet departed Nanjing with imperial letters and lavish gifts intended to secure and expand Ming diplomatic-commercial relations across maritime Asia and the Indian Ocean world.
The expedition assembled near the Min River/Changle area, a key Fujian littoral zone tied to shipbuilding, provisioning, and staging for Indian Ocean routes.
On the return from the first voyage, Zheng He’s forces fought and defeated the pirate leader Chen Zuyi at Palembang, strengthening Ming control over a crucial trade corridor linked to the Strait of Malacca.
After capture, Chen Zuyi was taken to the Ming capital and executed, reinforcing the voyages’ security function: suppressing threats to regional maritime commerce and tribute shipping.
Zheng He’s second expedition revisited major ports across Southeast Asia and India, sustaining the diplomatic-tribute network and the exchange of high-value goods associated with the voyages.
The third voyage expanded and consolidated earlier circuits; accounts emphasize repeated Indian port calls and the fleet’s role in projecting Ming authority along commercial sea lanes.
The fourth expedition pushed the Ming fleet westward to Hormuz, linking Ming diplomacy and commerce to a major entrepôt in Gulf trade networks.
The fifth voyage primarily returned foreign envoys and continued to East Africa, underscoring the voyages’ function as state-managed diplomatic exchange intertwined with long-distance trade.
Court orders initiated the sixth expedition and provided gifts (including paper money and robes) for foreign envoys—evidence of the voyages’ bureaucratic organization and tribute diplomacy.
The Yongle Emperor ordered a suspension of the voyages, signaling shifting court priorities even as maritime diplomacy and trade networks remained significant.
The sixth expedition focused on returning remaining envoys to their home polities from Southeast Asia toward the western Indian Ocean and East Africa, maintaining tributary ties while the program faced increasing constraints.
The treasure fleet returned with envoys, marking the end of the last Yongle-era voyage and a turning point toward a prolonged pause in state-sponsored long-distance expeditions.
Yongle’s death removed a key patron of the treasure-voyage enterprise; subsequent policy shifts at court contributed to the program’s suspension.
The Hongxi Emperor formally ended the treasure-voyage program, reflecting changes in fiscal and strategic priorities that reduced state support for large maritime expeditions.
After years of suspension, the Xuande Emperor authorized a final expedition. The seventh voyage again reached Southeast Asia, South Asia, and westward routes, attempting to reassert Ming presence within established Indian Ocean networks.
Zheng He died in Calicut (Kozhikode) during the final expedition; leadership continued to bring the fleet home, but the program did not resume afterward.
The fleet returned to China in 1433, and the Ming court did not dispatch further treasure voyages, closing a major phase of state-directed maritime diplomacy and trade projection.
