Pengiran Muhammad Yusuf bin Pengiran Haji Abdul Rahim (2 May 1923 – 11 April 2016), pen name Yura Halim, was a Bruneian civil servant, diplomat, educator and noble poet. He served as Brunei's state secretary from 1964 to 1967 before becoming the third (chief minister) from 1968 to 1972. He later held prominent diplomatic roles as Brunei's high commissioner to Malaysia from 1995 to 2001 and ambassador to Japan from 2001 to 2002. Additionally, he was appointed a member of the Legislative Council of Brunei (LegCo) in 2011, serving in the position until his passing in 2016.
He was one of the "Three M's" or "Three Musketeers," feared by the British government, alongside Marsal Maun and Pengiran Muhammad Ali. As a prominent member of the Brunei Malay Teachers Association (PGGMB), Pengiran Muhammad Yusuf, along with figures like Jamil Al-Sufri, played a pivotal role in opposing British colonial influence in Brunei during the early 1950s. A hibakusha, he was widely recognised for his contributions to Brunei's governance, literature, and diplomacy. Notably, he became the first Bruneian to receive an honorary doctorate from Hiroshima University and wrote the lyrics to the national anthem .
Early life and education Pengiran Muhammad Yusuf was born in Kampong Kandang in Tutong District on 2 May 1923. He was educated at a Malay school in Tutong town and trained at Sultan Idris Training College (SITC) in 1940, but his studies were interrupted by the Japanese invasion in late 1941. He returned to Brunei in December 1942 and attended a Japanese language class in Brunei Town and later in Kuching. Towards the end of 1943, he was selected, along with a few students from the Borneo territories, to study in Japan. He enrolled in a language course at the Kokusai Gakuyukai International Institute in Tokyo and later attended Hiroshima University of Literature and Science in 1945 to study language and education.
Pengiran Muhammad Yusuf, along with other Malay-educated figures like Salleh Masri and Jamil Al-Sufri, was at the forefront of agitation in Brunei following the Japanese occupation. Their early influences may have stemmed from their training at institutions such as the SITC in British Malaya. Aged 18, he was among the Brunei students trained by the Japanese during World War II and was selected for the Nanpō Tokubetsu Ryūgaksei program. He trained in Japan, attending Hiroshima University, and was living in Hiroshima during the atomic bombing, which caused him to suffer radiation poisoning. He returned to Brunei in March 1946 and continued his efforts in Brunei's post-war political developments.
Career Early career Pengiran Muhammad Yusuf began his career as a teacher at Bukit Bendera Malay School, Tutong on 1 January 1939. He was later elected vice president of (BARIP) when it was formed on 12 April 1946. BARIP aimed to achieve Brunei's independence and promote the social and economic advancement of the Malay community, though it was influenced by Indonesian nationalism but did not prioritise independence for Brunei. Instead, the group focused on uniting young Bruneians to protect local rights against immigrants and advocated for the restoration of the British Residency to safeguard Malay interests, leading to the return to civil government in July 1946. He played a key role in bringing the issue of the arch to Sultan Ahmad Tajuddin's attention. When the British Resident ordered the protest slogan to be changed, he led BARIP in refusing to comply, threatening to bring down the arch. The sultan intervened, overruled the British Resident's order, and sided with BARIP, which he was not surprised by, as he knew the sultan shared concerns about rising Chinese influence in Brunei.
In 1947, Pengiran Muhammad Yusuf wrote the lyrics for for BARIP, which would later be adopted as Brunei's national anthem. Later that year, as the deputy president of BARIP, he was sent back to Malaya to resume his teacher training, which had been interrupted by the war. Upon his return in 1950, he was posted to Temburong District until 1954. His transfer, along with those of other leaders, weakened BARIP, leading to its decline. Pengiran Muhammad Yusuf believed the sultan, despite the British Resident's advice, wanted the process of gauging public opinion on constitutional proposals to be a Bruneian matter. Consequently, he was appointed secretary to the , a constitutional advisory committee, in 1953. The public's response to the Sultan Omar Ali Saifuddien III's proposal was overwhelming, with young educated Bruneians, especially teachers, engaging in discussions about democracy and independence. By late 1953, the committee had completed its tour of Brunei and, in early 1954, was tasked with studying Malaya's constitutions and administrative procedures. As secretary, Pengiran Muhammad Yusuf compiled a 50-page report from the visit to the four districts, which was presented to Sultan Omar Ali Saifuddien III in 1954.
State information officer After transferring to the Information Department in 1954, Pengiran Muhammad Yusuf was sent to South Devon Technical College in Torquay, United Kingdom, to study public and social administration, where he remained until 1957. During this time, he was appointed to a committee investigating housing allocations for government officers in December 1956. Upon his return, he rejoined the Information Department and was later elected as the country's first information officer on 1 January 1957. Later that year, he was appointed as an unofficial member of the State Council, a role he held until the enactment of the new constitution. That same year, he accompanied the sultan to London for key constitutional discussions with the Colonial Office. During these discussions, he strongly supported the sultan’s call for appointing a chief minister, state secretary, and state financial officer to align with or follow the constitution’s implementation. He argued that the change had been delayed since 1953 and reflected the people's wishes.
In February 1958, Pengiran Muhammad Yusuf, alongside Pengiran Ali and Marsal, was appointed to review the draft Agreement between Brunei and the United Kingdom and propose a new version after the State Council insisted on discussing it without the Anthony Abell present. Later, in May 1958, as the state information officer, Pengiran Muhammad Yusuf was identified by Abell as one of three key figures, alongside Pengiran Ali and Marsal, who were vocal in the State Council. E. R. Bevington noted that they often acted as spokesmen for the sultan and played a significant role in advocating for amendments to both the constitution enactment and the draft agreement.
Pengiran Muhammad Yusuf was a member of Brunei's delegation to the 1959 constitutional negotiations in London, which included all Malay State Council members. Advised by two lawyers, the delegation discussed key issues such as the transfer of the British Resident's powers, nationality, LegCo qualifications, defence, and the high commissioner's reserve powers. On 23 March, at the London Conference, he participated in six plenary sessions chaired by the state secretary. He was involved in discussions, alongside Brunei's legal advisers, on key constitutional matters, including Brunei’s administrative separation from Sarawak.
In October 1959, Pengiran Muhammad Yusuf represented Brunei at a youth conference in Japan, where a key decision was made to advocate for the use of atomic energy for global peace and prosperity, not for destruction. He emphasised the importance of youth worldwide learning science and adapting to the Atomic Age, urging them to prepare not only as national leaders but also as global leaders who champion peace and prosperity. The conference, attended by representatives from 25 countries, was officially opened by Japan's education minister. Later, he witnessed the granting and signing of Brunei's constitution at the Lapau on 29 September 1959. Following the signing, he was appointed as a member of both the LegCo and Executive Council.
Pengiran Muhammad Yusuf was confirmed as the state information officer in December 1960 after the LegCo's unofficial members walked out in protest of their ideas being rejected, following growing hostilities between the locals and the Malayan contingent over the perceived influence of Malayan officers. In July 1961, he was promoted to deputy state secretary, succeeding Marsal. The high commissioner noted that his appointment, along with Marsal's, would have previously been met with concern due to their nationalist leanings and close ties with the (PRB). Pengiran Muhammad Yusuf, alongside Marsal, was praised for addressing a significant backlog of administrative tasks in Brunei, clearing around 600 files in the State Secretary's Office within four months of their appointments. His promotion in August 1961, which included roles as deputy state secretary and director of broadcasting and information, reinforced his alliance with the sultan and marked a shift towards Bruneian officers in senior government positions, reducing reliance on Malayan officials.
In that same month, George Douglas-Hamilton visited Brunei to discuss the Malaysia Plan with the sultan but failed to secure his commitment. Feeling betrayed by Tunku Abdul Rahman, who had threatened to withdraw officers from Brunei, the sultan turned to his traditional advisers—Marsal, Pengiran Ali, and Pengiran Muhammad Yusuf—who favoured an isolationist approach. The sultan refused to discuss the Malaysia Plan, citing constitutional and treaty restrictions. However, in late November 1961, the sultan informed the Executive Council of his decision to welcome the Malaysia Plan, with no discussion or vote on the matter. It was believed that he had enlisted the support of Marsal, Pengiran Ali, Pengiran Muhammad Yusuf, and Abdul Aziz Zain, whom he had appointed to advise him on the issue. Pengiran Muhammad Yusuf later attended the second Malaysian Solidarity Consultative Committee (MSCC) meeting in Kuching in mid-December 1961 as an observer, where key issues like federal representation, immigration, and economic development were discussed.
At the final MSCC meeting in Singapore on 7 February 1962, the Malaysia Plan was agreed with particular protections for Borneo areas. A memorandum, signed by all delegates including the Brunei representatives, was submitted to the Cobbold Commission, set up by the Malayan and British governments. The Brunei delegation consisted of Pengiran Muhammad Yusuf, along with Pengiran Ali, Jamil, Lim Cheng Choo, and Abdul Aziz as the advisor. In March, while Pengiran Ali and Pengiran Muhammad Yusuf openly supported the Malaysia Plan and signed the MSCC's memorandum, Abdul Aziz informed Dennis White that Dato Marsal, Ibrahim Mohammad Jahfar was wavering in his support for the plan. Pengiran Muhammad Yusuf was involved in the Brunei government's discussions around the Malaysia proposal in April and played a key role in resolving tensions within the government, particularly between Marsal and Pengiran Ali, by mediating their rift. He was part of the group supporting Malaysia and helped influence others towards approval of the proposal.
