# Jabatan Adat Istiadat Negara

The Jabatan Adat Istiadat Negara (abbrev: JAIN) is a government department under the Prime Minister's Office that functions to guarantee the constant maintenance of Royal Customs. It has been translated literally as the Office of State Customs, the Department of the State Customs or the State Department of Customs and Traditions, even though it does not have an English name. In order to guarantee that the practice and implementation, particularly the Istiadat Diraja (Royal Ceremonies), are always in accordance with the philosophy of Melayu Islam Beraja, preaching and teaching the public through lectures, briefings, and workshops on Adat Istiadat (Customs) are regularly held.

## History

On 1 July 1954, the Jabatan Adat Istiadat, Ugama dan Kebajikan Masyarakat (Department of Customs, Religious and Social Welfare) was founded. Its first offices were located at the General Office of the Royal Secretariat Building (now known as the Secretariat Building). With the consent of Sultan Omar Ali Saifuddien III, the department was established with the royal appointment of Pengiran Anak Haji Mohamed Alam as the Pegawai Adat Istiadat, Ugama, and Kebajikan Masyarakat (Customs, Religious, and Social Welfare Officer).
With the authority granted by the Brunei 1959 Constitution, the Religious Section became the Department of Religious Affairs on 29 September 1959, and Pengiran Dato Seri Paduka Haji Ali became its new head. The Jabatan Adat Istiadat dan Kebajikan Masyarakat (Department of Customs and Social Welfare) was first founded in October 1961, as a result of the Kebajikan Masyarakat (Social Welfare Section) appointing Mohamed Salleh bin Haji Masri as its director, and the creation of the Jabatan Kebajikan Masyarakat Brunei (Brunei Social Welfare Department). Since then, Pengiran Anak Haji Mohamed Alam has served as the Yang Di-Pertua Adat Istiadat Negara of the Jabatan Adat Istiadat.
Following the construction of the Lapau in 1968, the Jabatan Adat Istiadat Negara (JAIN) relocated and took up temporary residence at the bottom of the structure. His son, Pengiran Anak Haji Mohammad Yusof, took over as head of JAIN on 1 December 1981. The development of the JAIN happened gradually under his direction. The Sultan of Brunei has been using JAIN since its founding, particularly when it comes to giving someone national honours. JAIN is currently housed in a permanent structure next to the Lapau. Pengiran Anak Haji Abdul Aziz's work and endeavours led to the foundation of this structure.
