Meng Da
The Xincheng Rebellion was a revolt that took place in the state of Cao Wei between late 227 and early 228 CE during the Three Kingdoms period. The rebellion was initiated by Meng Da, a former Shu Han general who defected to Wei and was placed in charge of Xincheng Commandery (located in the vicinity of present-day northwestern Hubei) in Jing Province. The revolt was swiftly suppressed within a month by the Wei general Sima Yi. Meng Da was captured and executed.
