The Jementah Civil War broke out in 1879 in Jementah in northern Johor when Tengku Alam Shah, the heir of late Sultan Ali of the autonomous principality of Muar refused to surrender the principality to the central administration of Abu Bakar, the then Maharaja of Johor.

The aftermath of the conflict led to the consolidation of Johor's rules over Muar territory again and the opening of Muar town by Sultan Abu Bakar as the first sultan of modern Johor.
