A Maritime Empire’s Southernmost Outpost

When discussing the territorial reach of China’s imperial dynasties, many envision the vast land conquests of the Tang or Yuan. Yet the Ming Dynasty (1368–1644) achieved something unprecedented: establishing an official administrative outpost near the equator—the Old Harbor Pacification Commission (旧港宣慰司) in present-day Palembang, Indonesia. This marked the southernmost extension of Chinese territorial governance in history. How did this tropical archipelago become part of the Ming empire?

The Fractured Seas of Southeast Asia

The early Ming faced threats on all frontiers. While the Yuan dynasty had collapsed, Mongol remnants remained potent. Japanese pirates ravaged coastal regions, and Korea maintained ties with the Northern Yuan. Meanwhile, the maritime Southeast Asian world was equally volatile.

Since the 7th century, the Srivijaya Empire (三佛齐) had dominated the Malacca Strait as a critical hub connecting China, India, and the Arab world. Chinese records like Zhu Fan Zhi (《诸蕃志》) noted: “Their kingdom controls the throat of all foreign ships.” By the Ming era, Srivijaya was weakening. After a failed invasion of Ceylon (Sri Lanka), its territories fell to Java’s rising Majapahit Empire.

In 1397, Majapahit forces sacked Srivijaya’s capital at Old Harbor (Palembang). The royal family fled west, eventually founding the Malacca Sultanate. Left behind was a powerful Chinese merchant community that would reshape the region’s destiny.

The Chinese Diaspora Takes Charge

During the Song-Yuan period, Chinese merchants had settled across Southeast Asia. Ming founder Zhu Yuanzhang’s strict maritime prohibitions (海禁) inadvertently swelled these communities, as coastal residents fled overseas to escape poverty. At Old Harbor, these expatriates rallied behind Liang Daoming (梁道明), a Guangdong-born leader who declared himself the new Srivijaya king. During the Ming civil war (1399–1402), Liang recruited thousands from China’s coast to fortify his position against Majapahit.

Meanwhile, another faction emerged—the pirate warlord Chen Zuyi (陈祖义). Once a minor official in Palembang, Chen built a fearsome fleet that extorted merchants from Japan to India. The Ming placed a staggering 500,000 tael bounty on his head, equivalent to tons of silver. His base at Old Harbor’s strategic choke point threatened all regional trade.

Zheng He’s Decisive Intervention

Emperor Yongle’s solution was Admiral Zheng He’s (郑和) legendary voyages. In 1405, Zheng’s 28,000-strong armada arrived at Old Harbor. Liang Daoming immediately pledged allegiance, but Chen Zuyi plotted treachery—planning to ambush Zheng’s fleet. Warned by Liang’s deputy Shi Jinqing (施进卿), Zheng set a counter-trap. His ships encircled Chen’s pirates, destroying 10 vessels and capturing Chen alive. The warlord was executed in Nanjing.

With the pirate menace eliminated, Yongle established the Old Harbor Pacification Commission in 1407, appointing Shi Jinqing as its commander. This marked the Ming’s formal governance over territory 3,000 miles south of Beijing. Strategically positioned along the Malacca and Sunda Straits, it served as a vital resupply hub for Zheng He’s subsequent voyages.

The Unique Governance of Old Harbor

Unlike typical Ming frontier administrations, Old Harbor operated under a shared Sino-Javanese framework. While nominally subordinate to Majapahit (after a 1406 incident where Javanese forces accidentally killed 170 Ming sailors), it maintained autonomy through a council of four Chinese Muslim families. Ming records ambiguously list it both as territory (“under imperial command”) and foreign state (“customs identical to Java”). This duality reflected pragmatic diplomacy—acknowledging Javanese suzerainty while securing Ming influence.

After Shi Jinqing’s death in 1423, his daughter Shi Erjie (施二姐) inherited leadership despite Yongle initially approving her brother. She proved capable, but Ming maritime retrenchment after Yongle’s death left Old Harbor vulnerable. By 1440, Java absorbed the settlement entirely.

Legacy: The Enduring Chinese Presence

Though the Pacification Commission lasted barely 33 years, its impact endured. Chinese merchants continued dominating Old Harbor’s commerce, using Ming copper coins as late as the 16th century. Today, Palembang’s Chinese community—descendants of these Ming-era settlers—remains vibrant.

The Old Harbor experiment demonstrated Ming China’s capacity for innovative frontier governance, blending military deterrence, diaspora networks, and cultural adaptability. In an era without modern international law, it crafted a model of shared sovereignty that stabilized a critical global crossroads—a lesson in pragmatic statecraft that still resonates.
