Jiang (Chinese state)

In 1101 BCE, Yu the Great, the leader of China under the Xia Dynasty allocated a piece of land on the riverbanks of the Huai River to Genchu (Chinese: 玄仲) under the Fengjian system. Genchu was the son of Boyi, a legendary tribal leader who was loyal to Yu the Great, and the allocation of the land to Genchu was mainly for rewarding Boyi's family for Boyi's exemplary achievements in controlling the Great Flood. Chinese historian Guangyue He (Chinese: 何光岳) believes that the state was part of Dongyi, a group of tribes in eastern China during the Pre-Qin Era, and moved southwards to modern-day Henan after the Zhou conquest of the Dongyi. The state was made a vassal state of the Zhou Dynasty during the era of King Cheng, and during the era of King Mu, the state expanded westwards into parts of Zhongyuan[1][3][4]

According to the Records of the Grand Historian and Shiben, the State of Jiang was located in the southeastern part of Zhengyang County near the northern riverbanks of the Huai River during the Zhou Dynasty. The capital of Jiang at the time was a rectangular plot of land measuring 175,000 m² in size and existed until the Han Dynasty. It is estimated that about 10,000 people resided in the state at the time. The state was relatively prosperous during the Western Zhou Dynasty, but the continuous warfare during the Spring and Autumn Period and occasional flooding near the Huai River weakened the state. The state was also sandwiched between the more powerful states of Chu, Song, and Qi at the time, which limited the political, economic, and military influence of the state as Jiang had to be vassals of these larger states in order to maintain their sovereignty.

At some point between 671 BC and 626 BC, King Cheng of Chu arranged for his younger sister, Jiang Mi (Chinese: 江羋) to be married to the leader of the State of Jiang at the time.[5] The State of Jiang became more wary of Chu territorial expansion, and they allied with the hegemon of China, Duke Huan of Qi in 658 BC.[4][6]

After the death of King Cheng of Chu, Chu invaded the State of Jiang in 624 BC. The invasion was unsuccessful as the State of Jin intervened and drove Chu forces back to their homeland temporarily. In fall 623 BC, King Mu of Chu launched another invasion and successfully annexed Jiang. According to Zuo Zhuan, the annexation of Jiang deeply saddened Duke Mu of Qin.[1][4][7]
