Pengiran Muhammad Ali bin Pengiran Haji Muhammad Daud^[a] (4 October 1916 – 16 June 2005) was a Bruneian civil servant, educator and noble politician. He served as Brunei's first state religious affairs officer from 1960 to 1962 and was appointed speaker of the Legislative Council of Brunei (LegCo) in 1962 before becoming the country's first deputy menteri besar (chief minister) from 1962 to 1965.

He was one of the "Three M's" or "Three Musketeers,"^[b] feared by the British government, alongside Marsal Maun and Pengiran Muhammad Yusuf.^[3] As one of the founding members of the Brunei Malay Teachers Association (PGGMB).^[4][5] he was also a trusted confidante of Sultan Omar Ali Saifuddien III and played a crucial role in advancing Brunei's nationalist aspirations. He was instrumental in revising the 1959 constitution and negotiating the Anglo–Brunei Agreement.^[3]

Beyond his influence in politics, he was a distinguished educationist, contributing significantly to the introduction and expansion of Islamic religious education in Brunei. He also played a key role in shaping the country's national education strategy. In the early 1950s, he facilitated the admission of Brunei's first two students to Madrasah Aljunied Al-Islamiah in Singapore and spearheaded a program to send more Bruneian students there.^[4]

Additionally, he was the father-in-law of Princess Amal Nasibah, daughter of Sultan Omar Ali Saifuddien III.^[6][7][8]

Pengiran Muhammad Ali was born on 6 July 1916 in Kampong Pengiran Pemancha Lama, a village within Kampong Ayer.^[3] He received his early education at Jalan Pemancha Malay School in 1925 before continuing at Brunei Town Malay School until 1930, completing Standard V.^[9] On 8 February 1933, he began work as a student teacher for a short period.^[3] He later pursued further studies at Sultan Idris Training College (SITC) in Tanjung Malim, Perak, from 1934 to 1936.^[9]

Pengiran Muhammad Ali was appointed as an assistant teacher at Kuala Belait Malay School before becoming headmaster of Sengkurong Malay School in 1941.^[4] Upon returning home, he served as a senior teacher from 1939 to 1943 and was a founding member of the PGGMB, which was registered in 1939 but soon disrupted by the Japanese invasion. Following the war, he did not participate in the activities of Barisan Pemuda. In 1953, he was appointed as a member of the Tujuh Serangkai, a constitutional advisory committee.^[10] The following year, as a school teacher, he was selected as an observer in the State Council, representing the Brunei–Muara District. His role was to listen to discussions and report back to the District Advisory Council (DAC), with limited opportunities to speak unless permitted by Sultan Omar Ali Saifuddien III and the British Resident.^[11] From November 1954 until January 1957, he attended the State Council in this capacity.^[12]

During this period, Pengiran Muhammad Ali became an outspoken critic of the government, using his position to challenge policies in the State Council.^[13] Between 1954 and 1955, he was among the vocal teachers chosen as observers in the expanded State Council, which increasingly questioned and criticised British administration.^[3] Alongside figures like Marsal, he played a key role in transforming the council into a platform for debate, frustrating British officials. In 1954, he joined a two-week study tour of Malaya, where the committee examined governance, constitutional matters, religious affairs, and development. He recalled receiving advice from their Malay counterparts, who stressed the importance of preserving Brunei as a Malay Islamic sultanate to safeguard it from foreign influence.^[14]

"In June 1956, Anthony Abell instructed the incoming British Resident, Dennis White, to curb the influence of Pengiran Muhammad Ali and Marsal over the sultan.^[15] Despite this, from 1957 to 1959, Pengiran Muhammad Ali remained an unofficial member of the State Council while also serving as a Malay inspector of schools from 1957 to 1958.^[10] During this period, he was appointed chair of the committee on National Education Policy in 1957, following his role as coordinator of the Schools Feeding Program in 1956.^[4] In 1958, as chairman of the Brunei–Muara DAC, he stated that he would refer the sultan's proposal to appoint a chief minister and abolish the British Resident back to his council members for discussion.^[16] That same year, he was part of the Brunei delegation to London for constitutional talks, which included the Sultan and other key Malay members of the State Council. They were advised by Panglima Bukit Gantang and Neil Lawson, a lawyer who had played a role in Malaya's constitutional negotiations.^[17]

Pengiran Muhammad Ali played a key role in constitutional debates, particularly on 9 April 1958, when he clarified in a State Council meeting that the sultan would act on advice only if he deemed it beneficial to the state—contrasting with the 1905/1906 agreement, which required the British resident's advice to be followed.^[18] In May 1958, alongside Marsal and Abdul Hapidz, he proposed Brunei's withdrawal from the inter-territorial conference, arguing it provided no clear benefits to the state. Although the sultan did not decide immediately, Brunei’s participation in the conference soon ended.^[19] In June 1958, a report by E.R. Bevington, endorsed by Abell, blamed Pengiran Muhammad Ali, Marsal, and Pengiran Yusuf for causing political difficulties in Brunei, accusing them of dominating State Council discussions, influencing the sultan, and pushing for constitutional amendments.^[20] Earlier, in February 1958, Pengiran Muhammad Ali, along with Pengiran Yusuf and Marsal, had been appointed by the State Council to review the draft agreement between Brunei and the United Kingdom, insisting on independent discussions before presenting a revised draft for British consideration.^[21] Following this, he was elevated to chief inspector of schools on 11 August 1958.^[3]

In 1959, Pengiran Muhammad Ali traveled to London as part of the sultan's constitutional delegation^[10] and participated in the London Conference on 23 March, where discussions focused on Brunei’s future constitutional arrangements. He attended six plenary sessions alongside senior officials such as Chief Minister Ibrahim Mohammad Jahfar, Marsal, and legal advisers.^[22] Later that year, he witnessed the granting and signing of Brunei's constitution at the Lapau on 29 September.^[23][24] Following the adoption of the 1959 constitution, he was appointed as the acting head of the Brunei Islamic Religious Council.^[12] From November 1959 to August 1962, he served as an unofficial member of both the LegCo and Executive Council.^[10]

In December 1960, he was involved in a walkout by the sixteen unofficial members of the legislative council after their proposals were rejected by the sultan. The members protested that motions passed by the council required the sultan's approval to be acted upon, which they believed undermined their authority. The crisis was later resolved when the sultan privately met with the members, and to ease tensions, Pengiran Muhammad Ali was promoted from school headmaster to state religious affairs officer.^[25]

From 1961 to August 1962, Pengiran Muhammad Ali served as the state religious affairs officer.^[10] In July 1961, Pengiran Muhammad Ali joined a delegation to Kuala Lumpur to resolve staffing tensions with the Malayan government. The sultan, reluctant to request the return of Malayan officers, secured replacements through negotiations. Following this, he remained head of religious affairs while Marsal was promoted to acting chief minister, and Pengiran Yusuf became deputy state secretary. Abell viewed all three as ardent nationalists who had previously opposed British influence in Brunei.^[26] On 29 July, the Standing Advisory Council on Defence, chaired by the sultan, convened to discuss internal security. With Ibrahim on medical leave, the sultan appointed his closest advisers, including Marsal and Pengiran Muhammad Ali, to join the council. They discussed potential law and order breakdowns and authorised the chief police officer to seek assistance from Sarawak and North Borneo while mobilising the Oilfields Security Force.^[27]

In late August 1961, as the sultan distanced himself from Malayan influence, he turned to his traditional advisers, including Pengiran Muhammad Ali, Marsal, and Pengiran Yusuf, who were believed to favour an isolationist stance.^[28] Despite constitutional and treaty constraints, the sultan later declared his support for the Malaysia Plan in November without consulting the Executive Council, relying on advice from Pengiran Muhammad Ali and others.^[29] In December, he attended the second Malaysian Solidarity Consultative Committee (MSCC) meeting in Kuching as an observer and signed the final memorandum, suggesting Brunei's tentative support for Malaysia. In his speech, he criticised opposition to the plan as unconstructive and questioned whether a northern Borneo federation would secure the sultan’s sovereignty or gain acceptance from Sarawak and North Borneo, reflecting Brunei's concerns about its role in the proposed federation.^[30]

At the final MSCC meeting in Singapore on 7 February 1962, the Malaysia Plan was agreed upon with protections for Borneo territories. A memorandum, signed by all delegates, including the Brunei representatives, was submitted to the Cobbold Commission. The Brunei delegation consisted of Pengiran Yusuf, Pengiran Muhammad Ali, Jamil, Lim Cheng Choo, and adviser Abdul Aziz Zain.^[31] In March, while Pengiran Muhammad Ali and Yusuf openly supported the plan and signed the MSCC memorandum, Abdul Aziz informed White that Marsal and Ibrahim were wavering in their support.^[32] From March to September, Ali briefly served as speaker of the Legislative Council.^[9] On 23 September, the sultan appointed him deputy chief minister, alongside the reconfirmation of Marsal as chief minister, to strengthen the government ahead of Partai Rakyat Brunei (PRB) members joining the councils.^[33] Two days later, he joined a Brunei delegation led by Marsal for exploratory talks with the Malayan government in Kuala Lumpur.^[34]

In December 1962, the sultan expressed his positive view of the Malaysia proposal, calling it "very attractive" due to the shared ties of religion, race, custom, and culture among the Malaysian states. This decision was influenced by the new attorney general, Abdul Aziz, and supported by Marsal, Pengiran Yusuf, and Pengiran Muhammad Ali. These leaders had helped clean up the state government, with Marsal and Pengiran Yusuf clearing a backlog of 600 files and passing key legislation, such as the Nationality Enactment, during the LegCo's budget session.^[35] Following the 1962 rebellion, the sultan sent Pengiran Muhammad Ali and Jamil to Kuala Lumpur for preliminary discussions on Brunei's terms for joining the proposed Malaysian Federation. However, during the 1963 negotiations, the sultan sought safeguards, particularly regarding oil revenue control, leading to a breakdown in talks. Brunei ultimately chose not to join the federation in July 1963, remaining a British protected state until its full independence in January 1984.^[36]

In late March 1963, the Brunei government made significant progress towards a decision on Malaysia, with a majority of the sultan's advisory council voting in favour of the proposal. However, tensions arose between Marsal and Pengiran Muhammad Ali, particularly over the report of the Malaysia commission. Marsal criticised Malayan officers, straining his relationships with them. The rift between Marsal and Pengiran Muhammad Ali was resolved with the help of Pengiran Yusuf, and Marsal, along with another member, changed their votes, leaving only Noor Abdul Razak opposed to Malaysia. The attorney general also worked on persuading A. M. Azahari to approve the proposal.^[37] He signed an agreement on behalf of the sultan's government with Clark (Brunei) Oil and Refining Corporation from Milwaukee, in a ceremony held inside the Secretariat Building.^[38] He resigned in 1965 to run for the district council^[39][12] and left his post as deputy chief minister on 18 September 1965, after being granted 436 days of leave.^[7]

After leaving the administration, Pengiran Muhammad Ali entered politics, though with limited success. He was first elected to the Brunei–Muara District Council in a by-election on 23 October 1965. In December of the same year, he founded Partai Kemajuan Rakyat (PAKAR),^[7] which was officially registered in February 1966 as a political party restricted to Malays and indigenous peoples. He advocated for amendments to the 1959 Constitution, arguing that it was inadequate for establishing an effective parliamentary government. His main objective was to unite Brunei’s nationalists under a single front for constitutional reform. In August 1966, following strong support, PAKAR was officially launched in Brunei Town.^[40]

On 31 July 1966, he became the founder and chairman of Barisan Kemerdekaan Rakyat (BAKER) after PAKAR merged with Barisan Rakyat Brunei (BARA). He later contested two by-elections for the LegCo in Temburong District but was unsuccessful in both, losing in January 1968 and again in April 1969. Disillusioned by the challenges of politics, Pengiran Muhammad Ali shifted his focus to business.^[7][39] By around 1996, he was serving as chairman of Swee Sendirian Berhad.^[41]

Pengiran Muhammad Ali died at his home in Kampong Madewa on 16 June 2005, at the age of 89. Prince Mohamed Bolkiah, the deputy sultan, attended his funeral to pay his respects. In line with the wishes of Sultan Hassanal Bolkiah, the national flag was flown at half-mast across the country in honour of him.^[9][7]

Pengiran Muhammad Ali married Hajah Nahriah around 1971,^[42] and they had several children, including Pengiran Kerma Raja Pengiran Haji Kamarulzaman,^[43] who married Princess Amal Nasibah on 19 July 1979.^[44] According to White's March 1962 report, Pengiran Ali's wife is a relative of Azahari.^[45]

On 19 April 1975, Pengiran Muhammad Ali was honoured by Sultan Hassanal Bolkiah with the cheteria title of Pengiran Pekerma Setia Diraja Sahibul Bandar, bearing the style Yang Amat Mulia.^[7]
