The Installation Ceremony of the Malaysian Sovereign is the Malaysian equivalent of a coronation, marking the beginning of the reign of the Yang di-Pertuan Agong as the Malaysian head of state.
Since 1957, the rite has been a part of Malaysian history, with 13 such ceremonies held, first at the Prime Minister's Residential Function Hall at Jalan Ampang in Kuala Lumpur, and in the State Palace from 1980 onwards. The old Istana hosted its final installation in 2007, and in 2012 the brand new State Palace at Jalan Duta held its first installation.
The ceremony is a hybrid of ceremonies found in 8 of Malaysia's nine royal states, which all have one similarity: all do not use a crown. Instead, a special headdress known as the Tengkolok Diraja (Royal Headdress) is used, except in Johor where the Sultan is crowned (as the State Government is heavily British-influenced).
The Installation of the Yang di-Pertuan Agong and his consort, the Raja Permaisuri Agong, is often held months after the Sovereign's election by the Conference of Rulers at the Istana Melawati in Putrajaya or at the Istana Negara, Kuala Lumpur. The installation is strictly ceremonial, as the Yang di-Pertuan Agong immediately takes office upon the expiry of the previous term, or in case of a vacancy, upon election. A simple inauguration ceremony is held on the day the Yang di-Pertuan Agong begins his term, in which the Sovereign takes the oath of office.
Since 2012, the new Istana Negara at Jalan Duta in Kuala Lumpur is the venue of the ceremonial enthronement, with Malaysia's television networks providing a live nationwide simulcast of the proceedings. Previously, installations were held at the old Istana Negara at Jalan Istana, also in Kuala Lumpur.
