Upon her husband's accession to the Perakian throne on 3 February 1984, she became the Raja Permaisuri of Perak with the honorific prefix of Tuanku before her given name. In Perak a queen consort of royal blood is known as a Raja Perempuan, while the title of Raja Permaisuri was reserved for commoner consorts. Her Royal Highness was officially proclaimed the Raja Permaisuri of Perak Darul Ridzuan on 9 December 1985 in a ceremony at the Istana Iskandariah in
Kuala Kangsar. Sultan Azlan Shah was elected as the ninth
Yang di-Pertuan Agong and during the oath taking and signing ceremony on 26 April 1989, Tuanku Bainun was proclaimed
Raja Permaisuri Agong. Tuanku Bainun is the first commoner ever to become Queen of Malaysia. She was crowned
Raja Permaisuri Agong on 19 February 1988 a new throne made of silver that replaced the ancient wooden throne used by Malaysia's eight previous queens. They held these titles until the end of Azlan Shah's term on 25 April 1994. She ceased to be Raja Permaisuri of Perak on 28 May 2014, after
her husband died. She was succeeded a month later by her daughter in-law,
Tuanku Zara Salim. == Royal family ==
