Installation of Sultan Yahya Petra of Kelantan as the sixth Supreme King.

He ruled from 21 September 1975 until 29 March 1979.

He was born Tengku Yahya Petra at Istana Balai Besar in Kota Bharu. He was the second son of Raja Ibrahim ibni Almarhum Raja Muhammad IV (b. 1897; reigned 1944–1960) but the first by his commoner wife, Embong binti 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 Raja Ismail ibni Almarhum Raja Muhammad IV. He was sent to the Francis Light School in Penang before continuing his studies in England. His uncle, Raja Ismail, appointed him Tengku Temenggong on July 21, 1939. He was later promoted to Tengku Bendahara on February 6, 1945 by his father, then Raja Ibrahim. He served in various Kelantan civil service posts from 1941 to 1948.

Raja Yahya Petra died in his sleep of an apparent heart attack at Istana Negara on March 29, 1979. His coffin lay in state at Istana Negara for a day and was then taken by plane to Kota Bharu where it was buried at the Langgar Royal Mausoleum.
