Biography
Family Background and Early Scholarship
Liu Jiao was born into the Liu family of Fengyi in Pei Commandery, the youngest son of Liu Zhuan (later honored as Grand Supreme Sovereign) and the younger half-brother of Liu Bang. Endowed with sharp intellect, literary zeal, and broad ambition, he was the most cultured among the Liu brothers. In his youth, he traveled to the Lu area to study the Classic of Poetry under Fuqiubo, a prominent disciple of Xunzi, alongside classmates Mu Sheng, Bai Sheng, and Master Shen. When Qin Shi Huang initiated the burning of books and burying of scholars, the students dispersed, and Liu Jiao returned to his native place. Nevertheless, his rigorous classical foundation and respect for moral learning remained deeply ingrained, laying the groundwork for his future governance in Chu.
Military Campaigns and Title of Lord
In the first year of the Second Emperor of Qin (209 BCE), widespread uprisings erupted. Liu Bang gathered followers in Pei, and Liu Jiao immediately joined his elder brother. Possessing shared political sensibilities, Liu Jiao gained Liu Bang's highest trust and served as an indispensable aide throughout the campaigns against Qin. Upon entering Bashang and accepting the capitulation of Ziying, Liu Jiao was enfeoffed as Lord of Wenxin. During the Chu-Han Contention, he accompanied Liu Bang into Hanzhong, helped retake Guanzhong, and assisted with internal coordination and logistical stability across numerous battlefields, rendering distinguished service to the founding of the Han dynasty.
Enthronement as King of Chu
In the sixth year of Emperor Gaozu (201 BCE), following the consolidation of the empire, Gaozu visited the Yunmeng region and removed Han Xin from his position as King of Chu. The former Chu territories were divided into two kingdoms: Liu Jia was made King of Jing, and Liu Jiao was enfeoffed as King of Chu to reward his monumental founding contributions. Liu Jiao established his royal seat at Pengcheng, presiding over Xue Commandery, Donghai Commandery, and Pengcheng Commandery, encompassing thirty-six counties. Given Chu's economic wealth and strategic significance in eastern China, Liu Jiao focused on rehabilitating the devastated populace, reducing punishments, and restoring agricultural productivity.
Patronage of Confucianism and Poetic Commentaries
Upon settling in Pengcheng, Liu Jiao actively demobilized troops and prioritized civic refinement. He invited his former academic companions Mu Sheng, Bai Sheng, and Master Shen to Chu, appointing them as Grand Masters and according them the highest honor as scholarly mentors. During the reign of Empress Dowager Lu, when Fuqiubo resided in Chang'an, Liu Jiao sent his second son Liu Yingke and Master Shen to Chang'an to complete their studies under Fuqiubo. In Chu, Liu Jiao and his sons gathered daily to recite the Classic of Poetry and ancient philosophical texts. Master Shen produced the earliest influential commentary known as the Lu Commentary, while Liu Jiao personally penned his own exegetical compilation entitled the Commentary of King Yuan on the Poetry. These endeavors turned Pengcheng into a national center of classical study. Liu Yingke earned widespread respect for his scholarship and was subsequently appointed Director of the Imperial Clan by Emperor Wen.
Defending the Dynasty and Final Years
During the regency of Empress Dowager Lu, the influence of the empress's relatives expanded rapidly. As a pivotal regional monarch, Liu Jiao utilized Chu's administrative and military stature to safeguard dynastic equilibrium in the east. When Empress Dowager Lu died, Liu Jiao cooperated closely with imperial princes and court veterans to crush the Lu family's attempted coup, vigorously endorsing the accession of Prince Liu Heng of Dai as Emperor Wen. In the first year of Emperor Wen (179 BCE), Liu Jiao died after reigning for twenty-three years and was posthumously designated King Yuan. As Crown Prince Liu Pifei had predeceased him, Emperor Wen elevated Liu Jiao's second son, Liu Yingke, to the throne as King Yi of Chu.
