Sultan Yahya Petra ibni Almarhum Sultan Ibrahim, GCMG, (Jawi:z سلطان يحي ڤيترا ابن المرحوم سلطان إبراهيم;z10 December 1917 – 29 March 1979) was the sixth Yang di-Pertuan Agong (King) of Malaysia from 21 September 1975 to his death, and twelfth (by some reckoning tenth) Sultan of Kelantan (1960–1979).
He was born on at 4:00 pm. Monday 10 December 1917, Tengku Yahya Petra at Istana Kota Lama, Sungai Kelantan, in Kota Bharu. He was the second son of Sultan Ibrahim ibni Almarhum Sultan Muhammad IV (b. 1897; reigned 1944–1960) by his third wife, Cik Embong binti Encik Daud (1899–1971), who was later promoted to the style Che Ampuan Besar by her son.
The young Tengku Yahya Petra was raised by his childless uncle, Tengku Ismail, later Sultan Ismail ibni Almarhum Sultan Muhammad IV. He was sent to the Francis Light School in Penang before continuing his studies in England. His uncle, Sultan Ismail, appointed him Tengku Temenggong on 21 July 1939. He was later promoted to Tengku Bendahara on 6 February 1945 by his father, then Sultan Ibrahim. He served in various Kelantan civil service posts from 1941 to 1948.
Tengku Indra Petra was the eldest son of Sultan Ibrahim and elder brother of Tengku Yahya Petra. After Sultan Ibrahim succeeded his childless brother Sultan Ismail, Tengku Indra Petra was appointed heir apparent with the title of Raja Muda on 25 October 1944. However, due to conflict with his father, he was dismissed from the post and removed from the line of succession by his father's decree on 1 February 1948. On the same day, Tengku Yahya Petra replaced his brother as heir apparent with the new title of Tengku Mahkota.
Tengku Indra Petra became a politician and was elected a Member of Parliament (MP) in the first federal legislative election of 1955. Tengku Indra's descendants have since disputed their family's exclusion from the line succession of the Kelantan throne.
Tengku Indra Petra did not preside over the installation of Sultan Yahya Petra's successor, Sultan Ismail Petra, It was Tengku Panglima Raja Tengku Ahmad who presided over installations of Sultan Ibrahim, Sultan Yahya Petra and Sultan Ismail Petra. Tengku Panglima Raja was the father of the former Sultanah of Johor, Sultanah Zanariah binti Tengku Ahmad.
Sultan Yahya Petra (as he became) succeeded his father a day after the latter's death on 9 July 1960. He was crowned on 17 July 1961 at Istana Balai Besar in Kota Bharu.
Sultan Yahya Petra served as Deputy Yang di-Pertuan Agong, the federal deputy king between 21 September 1970 until 20 September 1975.
During the election of the sixth Yang di-Pertuan Agong (the federal king), the most senior rulers Sultan Abu Bakar of Pahang and Sultan Ismail of Johor both declined to be considered. Sultan Yahya Petra also declined nomination at first due to having suffered a serious stroke, but changed his mind and was duly elected. His term began from 21 September 1975.
Malaysia's second prime minister Tun Abdul Razak died on 14 January 1976 less than four months into Sultan Yahya Petra's reign as Yang di-Pertuan Agong.
In 1977 a state of emergency was declared in his state following a political crisis and violence.
Sultan Yahya Petra died in his sleep of an apparent heart attack at the National Palace on 29 March 1979. His coffin lay in state at the National Palace for a day and was then taken by plane to Kota Bharu where it was buried at the Langgar Royal Mausoleum.
He was married to Tengku Zainab binti Tengku Sri Utama Raja Tengku Muhammad Petra (1917–1993), who was styled Raja Perempuan Zainab II (her stepmother-in-law was Raja Perempuan Zainab I, consort of Sultan Ibrahim) and Raja Permaisuri Agong. Sultan Yahya Petra and Raja Perempuan Zainab II had one son and five daughters. He also married Tengku Alexandria binti Tengku Yusuf and was given a son.
