Sultan Abu Bakar Ri’ayatuddin Al-Mu’azzam Shah Ibni Al-Marhum Sultan Abdullah Al-Mu’tassim Billah Shah (Jawi: Malay: سلطان أبو بكر رعاية الدين المعظم شاه ابن المرحوم سلطان عبد الله المعتصم بالله شاه; 29 May 1904 – 5 May 1974), was the fourth modern Sultan of Pahang.
Born on 29 May 1904 at Istana Hinggap, Pekan, he was the second son of Sultan Abdullah Al-Mu’tassim Billah Shah by his second wife, Kalsum binti Abdullah.[1]
Succeeding his father in 1932, he quickly became known as a friendly and approachable ruler by his subjects. During the Japanese occupation of Malaya, he discreetly encouraged resistance movements such as the Askar Wataniah, Force 136 and the Malayan Peoples' Anti-Japanese Army.[2]
However, due to his penchant for marrying commoners, including several popular actresses and singers, he was less popular with other Malay rulers and they declined to choose him as Yang di-Pertuan Agong of Malaysia on five separate occasions.
He was married to Tengku Ampuan Pahang Raja Fatimah, the daughter of Sultan Iskandar of Perak, in Kuala Kangsar, Perak. It was a marriage between two royal relatives.[3]
He died on 5 May 1974 at the Istana Peninjau, Kampung Padang Polo, Pekan at age 69 and was succeeded by his son Sultan Ahmad Shah.[4] [5]
