The Conference of Rulers (also Council of Rulers or Durbar, (Malay: Majlis Raja-Raja; Jawi: مجليس راج٢) in Malaysia is a council comprising the nine rulers of the Malay states, and the governors or Yang di-Pertua Negeri of the other four states. It was officially established by Article 38 of the Constitution of Malaysia, and is the only such institution in the world, according to the Malaysian National Library. Its main responsibility is the election of the Yang di-Pertuan Agong (King) and his deputy, the Timbalan Yang di-Pertuan Agong, which occurs every five years or when the positions fall vacant (either through death, resignation, or removal from office). Although its position in the process of elective monarchy is unique, the Conference of Rulers also plays a role in amending the Constitution of Malaysia and some other policies, in particular, those Articles which have been "entrenched", namely those pertaining to the status of the rulers, the special privileges of the indigenous Bumiputra (see Article 153 of the Constitution of Malaysia), the status of the Malay language as the national language, and the clause governing the entrenchment of such Articles.
