Sun–Liu territorial dispute
The Sun–Liu territorial dispute was a military conflict between the warlords Sun Quan and Liu Bei in 215 during the late Eastern Han dynasty of China. While Sun Quan and Liu Bei had initially formed an alliance in 208 against their common rival Cao Cao, both sides got into a territorial dispute over the territories in southern Jing Province (covering present-day Hubei and Hunan) in the early 210s. The dispute ended when both sides agreed to divide the territories along the Xiang River between their respective domains: Sun Quan took the lands east of the river while Liu Bei kept those west of the river. Despite a peaceful settlement to the territorial dispute, Sun Quan ultimately sent his forces to attack Liu Bei's territories in an invasion in 219 and succeeded in capturing all of them.
