Raja Abdul Aziz was born on 14 November 1887 at Kampung Bandar, Teluk Anson, Perak. He was the son of Raja Muda Musa ibni Almarhum Sultan Ja’afar Safiuddin Mu’azzam Shah Waliullah.
On 1 August 1918, he was appointed raja bendahara and four months later on 18 December 1918, he was appointed raja muda (crown prince) upon the death of Sultan Abdul Jalil and resided in Teluk Anson. He became the Raja Muda of Perak in 1919 during the reign of his brother-in-law, Sultan Iskandar Shah Ibni Almarhum. He became the 31st Sultan of Perak in 1938 succeeding Sultan Iskandar.[1]
In 1948, he began to show poor health and was advised by his doctors to go to Lumut for a change of air. However, he died suddenly at the Lumut Rest House on 26 March 1948. Almarhum was interred at the Al-Ghufran Royal Mausoleum in Bukit Chandan and the posthumous title Marhum Nikmatullah was conferred upon him and was 60 years old when he died. He was succeeded by his cousin, Sultan Yussuf Izzuddin Shah.
