Sultan Ahmad Shah was the fifth modern Sultan of Pahang, and also served as the seventh Yang di-Pertuan Agong of Malaysia from 26 April 1979 to 25 April 1984. His abdication as Sultan was decided by the Royal Council at an extraordinary meeting on 11 January 2019. A special amendment was passed on 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 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.
