Cause → Event → Consequence
Xu, once the dominant power of the Huai River valley, was weakened by internal unrest and repeated wars from the start of the Spring and Autumn period. As Xu's influence over eastern Hubei, southern Henan, and central Anhui declined, Chu expanded into those regions, prompting Xu to join a coalition of northern states, led by Qi, against Chu's growing power.
In spring 645 BC, Chu invaded Xu's southern heartland, and the northern coalition dispatched a relief force to check Chu's expansion. The opposing armies met at Loulin in the winter of 645 BC. The coalition forces were defeated in the ensuing engagement, leaving Xu exposed and Chu's eastern conquests unchecked.
Chu's victory at Loulin marked the beginning of Xu's irreversible decline as a regional power. It also weakened Qi's standing as the dominant hegemon of the Chinese states, accelerating the broader shift in the balance of power during the Spring and Autumn period.
