 After Liu Bei's son Liu Shan succeeded his father as emperor in 223, Jiang Wan gradually rose to prominence under the regency of Zhuge Liang, the Imperial Chancellor of Shu.Between 228 and 234, while Zhuge Liang was away leading Shu forces on the Northern Expeditions against Shu's rival state Wei, Jiang Wan took charge of internal affairs and provided logistical support to the Shu forces at the frontline.After Zhuge Liang's death in 234, Jiang Wan succeeded him as regent and did well in gaining the Shu people's confidence and leading them into a post-Zhuge Liang era.
