Shortly after Abu Bakar became the Temenggong of Johor, he sent a letter to Sultan Ali to reassert of Johor's sovereignty over Segamat. Continued disputes over the sovereignty of Segamat led to an outbreak of a war between the Temenggong's men with the Sultan's. Eleven years later in 1873, attempts made by Suliwatang to collect custom taxes from inhabitants at the Muar estuary led to further conflict with Abu Bakar's (who became Maharaja in 1868) men.[24]
