This research investigated the elite's literary work, which employed traditional writing but presented innovative and progressive ideas. The Syair Perlembagaan Negeri Brunei manuscript is a tangible example of Sultan Omar Ali Saifuddien III's conviction in bringing renewal, progress, and development to Brunei Darussalam. This study used a descriptive qualitative method with historical research techniques, including psychological, historical, political, sociological, and theological approaches. This research revealed that Sultan Omar Ali Saifuddien III lived as an ordinary citizen from a young age, influencing his life circumstances and thinking. Moreover, the 19th-century Sultanate of Brunei had a political system and administrative structure based on three important institutions at the central government level: Perajaan (Sultanate), Wazir, and Ministers. The Syair Perlembagaan Negeri Brunei also exemplifies Sultan Omar Ali Saifuddien’s (SOAS) dedication to Brunei Darussalam's progress and development. In the five decades since the Constitution of Brunei's establishment in 1959, the country has made significant progress. Sultan Omar Ali Saifuddien III played a pioneering role in allowing the Five-Year National Development Plan in 1955. The Syair Perlembagaan Negeri Brunei highlights the importance of laws and constitutions in a nation's organization and stability. Thus, establishing the Constitution of Brunei in 1959 was a significant step towards achieving full independence and self-rule.
