Installation
Tuanku Abdul Rahman was installed as the first Yang di-Pertuan Agong of independent Malaya on 13 September 1957 at the throne room of the Istana Negara.
As Malay rulers do not traditionally possess crowns, he was installed by kissing the royal kris of state (keris kerajaan) to the beat of the nobat, a tradition which has been followed by every Yang di-Pertuan Agong since.
In honour of Tuanku Abdul Rahman, all subsequent Yang di-Pertuan Agong of Malaysia have also used the headdress Dendam Tak Sudah (literally Unending Revenge), the fashion employed in Negeri Sembilan.
