Qi State

Lore & Background

Qi emerged when lands on the Shandong peninsula were granted to Jiang Ziya, who remained loyal during the Three Guards' rebellion. The state suppressed revolts by Shang prince Wu Geng and Dongyi polities like Pugu by 1026 BCE. Under Duke Huan (r. 685–643 BCE), Qi consolidated power through county systems and monopolies on salt and iron, annexing several neighboring states including Tan (which had already been annexed by Qi in 684 BCE). In 667 BCE, lords of five states elected him leader; King Hui of Zhou named him Bà ('hegemon-protector'). He intervened in Lu, defended Yan from Western Rong, drove off Northern Di nomads after they invaded Wey and Xing, and led an eight-state alliance in 656 BCE that primarily campaigned against Chu, not a conquest of Cai itself. After his death, succession wars weakened Qi until the Tian clan dominated by 532 BCE, eventually replacing the Jiang rulers fully in 386 BCE.

In Their Own Story

In 209 BC, aristocrat Tian Dan restored Qi as King of Qi but died fighting Qin general Zhang Han in 208 BC. His cousin Tian Rong drove out the puppet king Tian Jia and installed Tian Shi, then rebelled against both him and Xiang Yu's appointee Tian Du in 206 BC, declaring himself king. After Xiang Yu killed Tian Rong in 205 BC, his brother Tian Heng recovered Qi territory and enthroned Tian Guang. In 203 BC, Liu Bang's envoy Li Yiji secured an alliance, but Han Xin attacked anyway. Enraged, King Tian Guang boiled Li Yiji alive before being defeated by Han Xin and Long Ju. Long Ju fell in battle; Tian Guang died fleeing. Tian Heng fled with 500 men to a coastal island, later committing suicide near Luoyang in 202 BC after being summoned by Liu Bang—his followers then all took their own lives.

Reader's Guide

Qi's culture featured distinct customs and dialects, noted in texts like the Yu Gong describing nine regional zones. Wu Qi observed that while Qi had numerous troops, their organization was unstable due to unfair wages and arrogant leadership; he advised splitting attacks on their flanks to cause disarray. Confucius admired the perfect performance of Shao music in Linzi. The famous Jixia Academy hosted scholars across China not as a physical building but as an informal intellectual collaboration, producing works like the Yanzi Chunqiu. Architecturally, Qi cities were nearly rectangular with grid-like roads; palaces faced south, flanked east by ancestral temples and west by god temples.
