Sultan Ahmad al-Muadzam Shah

Sultan Ahmad Al-Muʽazzam Shah ibni Almarhum Raja Bendahara Sri Maharaja Tun Wan Ali was the sixth raja bendahara of Pahang and the founder and first modern sultan of Pahang. Commonly known as Tun Wan Ahmad before his accession, he seized the throne in 1863 after defeating his elder brother Tun Mutahir in the Pahang Civil War, assuming the title Sri Paduka Dato' Bendahara Siwa Raja Tun Ahmad. In the early years of his reign, Pahang descended into turmoil, with various attempts made by the surviving sons of Tun Mutahir, based in Selangor, to overthrow him. This led to Pahang's direct involvement in the Selangor Civil War that brought it to a conclusive end.
