Former Yan

Yan, known in historiography as the Former Yan, was a dynastic state of China ruled by the Murong clan of the Xianbei during the Sixteen Kingdoms period. From Liaoning, the Former Yan later conquered and ruled over Hebei, Shaanxi, Shandong and Henan at its peak. They were notably the first of several Xianbei states to have establish their rule over the Central Plains. The prefix of "Former" is used in historiography to distinguish them from the other Yan states that came after them, such as Later Yan.
