Ahmad Shah of Pahang (died 2019)

Sultan Haji Ahmad Shah Al-Musta’in Billah ibni Almarhum Sultan Abu Bakar Ri’ayatuddin Al-Mu’azzam Shah was Sultan of Pahang from 1974 until his abdication in 2019, and the seventh Yang di-Pertuan Agong, from 1979 to 1984. His abdication as sultan was decided by the Royal Council at an extraordinary meeting on 11 January 2019. A special amendment was made to the state constitution that gave the body more power for this decision, citing the Sultan's incapability to rule due to his failing health. The abdication was announced the next day which was retroactively effective on the day of the Royal Council meeting, paving the way to his son, Abdullah to succeed him as sultan immediately, and subsequently be elected as the next Yang di-Pertuan Agong later the same month.
