Sòng (simplified Chinese: 宋国; traditional Chinese: 宋國) was a state during the Eastern Zhou's Spring and Autumn Period (770-476 BC) with its capital at Shangqiu. In 701 BC, a political marriage between Lady Yong of Song (宋雍氏) and Duke Zhuang of Zheng (as well as the capture of Zhai Zhong (祭仲), a leading warrior) empowered Song to manipulate the administration of Zheng.
After King Wu overthrew the last ruler of Shang, marking the transition to the Zhou Dynasty, the victor was honor-bound by feudal etiquette to allow the defeated house (Shang) to continue offering sacrifices to their ancestors. As a result, for a time Shang became a vassal state of Zhou, with the Shang heir Wu Geng allowed to continue ancestor worship at Yin (殷).
However, after King Wu’s death, Wu Geng fomented a rebellion and was killed by the Duke of Zhou. Another Shang aristocrat, Weizi (微子), was granted land at Shangqiu (商邱 ‘the hill of Shang’), where the capital of the new State of Song was built.
In 651 BC, Duke Huan of Song (宋桓公) died, leaving the district to be ruled by Duke Xiang, who reigned from 651 to 637 BC. He was considered a Hegemon by some, but was unable to maintain that role. He eventually fell to the troops of Chu.
In 355 BC, Dai Ticheng (戴剔成), a distant relative of the ruling royal line and once a minister of Duke Huan II, managed to usurp the throne. In 328 BC, Dai Yan, a younger brother of Ticheng, took the throne and declared himself to be King Kang of Song, with Ticheng murdered or exiled. The king was ambitious and had succeeded in beating troops from Chu, Wei and Qi and annexing Teng. However, the kingdom was finally annexed by Qi in 286 BC, with troops from Chu and Wei serving on behalf of Qi. Qin, which had been an ally of Song, refused to intervene for strategic and diplomatic reasons after being convinced by Su Dai from Wei. Su's predictions were proven correct and Qin benefited from the downfall of its former ally.
The philosopher Mozi references this state in the chapter "Obvious Existence of Ghosts", in which he mentions a number of Spring and Autumn Annals, including those of the Zhou, Yan, and Qi. The Spring and Autumn Annals of Song has not survived.
