Liu Bei's takeover of Yi Province was a military campaign by the warlord Liu Bei in taking control of Yi Province (covering present-day Sichuan and Chongqing) from the provincial governor, Liu Zhang. The campaign took place between the years 211 and 214 in the late Eastern Han dynasty; although the conflict between Liu Bei and Liu Zhang started in January or February 213 when the latter discovered the former secret communications and subsequently executed Zhang Song.^[a] It concluded with victory for Liu Bei and his successful takeover of the province from Liu Zhang in July 214. Yi Province (specifically, its capital of Chengdu and its nearby commanderies) would serve as the foundation of the state of Shu Han during the Three Kingdoms period.
