Magnus Maximus vs Wang Ling

Maximus's forces confronted Gratian near Paris. Gratian's army, largely composed of barbarian auxiliaries, deserted him. Gratian fled to Lugdunum (Lyon), where he was captured and executed on Maximus's orders. Maximus then controlled Gaul, Britain, and Spain.

Magnus Maximus, a Roman general of Spanish origin stationed in Britain, was proclaimed emperor by his troops. He crossed to Gaul with a large army, challenging the legitimate Western Emperor Gratian. This act initiated a civil war in the Western Roman Empire.

The Eastern Emperor Theodosius I, unable to immediately challenge Maximus, recognized him as co-emperor in the West. Maximus was granted control of Gaul, Britain, and Spain, while Valentinian II (Gratian's half-brother) retained Italy and Africa. This temporary peace lasted four years.

Maximus invaded Italy, forcing Valentinian II to flee to Theodosius in the East. Theodosius marched west and defeated Maximus's army at the Battle of the Save (modern Sava River in Croatia). Maximus was captured at Aquileia and executed.

Wang Ling was appointed Governor of Yang Province, overseeing Wei's eastern territories. He strengthened defenses against Wu and maintained order in the region, earning a reputation as a capable administrator.

Wang Ling led a rebellion against Sima Yi at Shouchun. He attempted to ally with Wu but was betrayed by his subordinates. Sima Yi's forces quickly suppressed the revolt, and Wang Ling was captured.

Wang Ling was executed by Sima Yi for plotting rebellion. He was forced to commit suicide, and his family was exterminated. This event solidified Sima Yi's control over Wei and eliminated a major rival.
