Later Jin Dynasty - Short Synopsis

The Later Tang Dynasty had a few years of relative calm, followed by unrest. In 934, Sichuan again asserted independence. In 936, Shi Jingtang, a Shatuo Turk jiedushi from Taiyuan - Shanxi province, was aided by the Manchurian Khitan Empire in a rebellion against the dynasty. In return for their aid, Shi Jingtang promised annual tribute and 16 prefectures in the Youyun area (modern northern Hebei province and Beijing) to the Khitans. The rebellion succeeded; Shi Jingtang became emperor in this same year.

Not long after the Jin Dynasty's founding, the Khitans regarded the emperor as a proxy ruler for China proper. In 943, they declared war on this kingdom, and within three years seized the capital, Kaifeng, thus marking the end of Later Jin Dynasty. But, although they had conquered vast regions of China, they were unable or unwilling to control those regions and retreated from them early in the next year.
