The Origins of Jianzhou and Its Early Ties to the Ming

The Jianzhou Guard’s ability to secure a tribute delegation of hundreds speaks volumes about the Ming court’s regard for this frontier power. This esteem stemmed from the unwavering loyalty of its first commander, Aha Chu (阿哈出), a Jurchen leader whose family had governed the Huligai region since the Yuan dynasty.

Aha Chu, known in Korean records as Yuhuchu, belonged to the Jin (or Gurun/Tong) clan, descendants of Jurchens from Yilan (依兰) along the Heilongjiang River. His ancestors had served as wanhu (万户, “myriarchs”) under the Yuan, and Aha Chu inherited this hereditary position. Amid the chaos of the late Yuan, he led his people southward in 1372 to escape raids by the Wudiha tribes, settling near the Tumen River bordering Korea.

His alliance with the Ming began in 1385 when one of his daughters entered the household of Zhu Di, then Prince of Yan. This marital bond deepened when Zhu Di became the Yongle Emperor. In 1403, Aha Chu traveled thousands of li to Nanjing, where the emperor honored him with the Chinese name Li Sicheng—a deliberate nod to Tang-era precedents of sinicizing Jurchen leaders. The Ming established the Jianzhou Guard, appointing Aha Chu as commander and his son Shijianu as deputy, granting them authority to recruit other Jurchen tribes.

The Ascent of Mengge Temür: A Pivotal Alliance

Aha Chu’s most consequential act was recommending Mengge Temür (猛哥帖木儿), a figure later revered by the Qing as their progenitor. Born in 1370 to the Odoli clan near modern Yilan, Mengge Temür inherited leadership at 15 after his father’s death. His skillful governance and resistance against Wudiha raids earned him respect, even from Korea, which granted him the title “High Myriarch.”

In 1405, Yongle dispatched envoys to recruit Mengge Temür, praising his “wisdom and understanding of heaven’s will.” Despite Korean attempts to dissuade him, Mengge Temür chose Ming allegiance, receiving the title of Jianzhou Left Guard commander in 1411. His forces—organized into left, center, and right armies—became a key Ming ally, notably during Yongle’s 1422 campaign against the Mongols.

Crisis and Transformation: The Womu River Tragedy

The golden age unraveled in 1433 during the “Womu River Incident.” Mengge Temür, assisting Ming envoys to recover captives from the renegade Yang Mudahu, was ambushed by a coalition of Jurchen and Mongol forces. Despite a valiant defense, he and his eldest son were killed, and the Jianzhou Left Guard nearly annihilated. This catastrophe forced survivors, including his brother Fanca and nephew Dongshan, to regroup under Ming protection.

Meanwhile, the original Jianzhou Guard, now led by Aha Chu’s grandson Li Manzhu (李满住), faced parallel threats. Korean invasions in 1433 and 1437 pushed them from the Hun River to the Suzi River valley, where they rebuilt at Fe Ala (费阿拉). Li Manzhu’s diplomacy secured Ming support, culminating in his 1442 promotion to都督佥事 (Vice Commissioner-in-Chief).

Legacy: From Ming Vassals to Qing Founders

The Jianzhou Guard’s story is one of resilience and strategic adaptation. Mengge Temür’s lineage, preserved through Fanca and Dongshan, eventually produced Nurhaci—the architect of the Later Jin and Qing dynasties. The Ming’s reliance on Jurchen leaders like Aha Chu and Li Manzhu, while initially effective, inadvertently nurtured the power that would later eclipse them.

Their legacy endures in Northeast China’s cultural landscape, from the ruins of Fe Ala to the Manchu identity that shaped imperial China’s final dynasty. The Jianzhou Guard’s rise exemplifies how frontier loyalties could forge empires—and how the Ming’s own policies sowed the seeds of its northern challengers.
