Tuanku Sir Syed Harun Putra ibni Almarhum Syed Hassan Jamalullail KCMG (Jawi: توانكو سر سيد هارون ڤوترا ابن المرحوم سيد حسن جمل الليل; 25 November 1920 – 16 April 2000) was Raja of Perlis from 1945 until his death in 2000, and the third Yang di-Pertuan Agong, the constitutional monarch of Malaysia, from 1960 to 1965.

He was the son of Syed Hassan bin Syed Mahmud Jamalullail (1897–18 October 1935), sometime Bakal Raja or heir presumptive to the throne of Perlis, by his commoner wife Wan Teh binti Wan Endut (1898 – 27 December 1952).^[1] Born in Arau, he was educated at the Arau Malay School and later at Penang Free School between 1937 and 1939.^[2] At the age of 18, he joined the Perlis administrative service, becoming a magistrate and in 1940, was transferred to Kuala Lumpur to serve as Second Magistrate in the Criminal Court.^[3]

The fourth Raja of Perlis, Syed Alwi ibni Syed Safi Jamalullail (born 1881; reigned 1905–1943) was childless. However, he had several half-brothers who were competing for the role of heir presumptive.^[4] The succession to the Perlis throne was not automatic and an heir presumptive had to be confirmed in that post by the State Council comprising the Raja and several others.^[5]

Syed Putra's paternal grandfather Syed Mahmud (died 1919), was the oldest son of Raja Syed Safi ibni Almarhum Syed Alwi Jamalullail (the third Raja). He was also a half brother of Raja Syed Alwi.^[6] He served as Raja Muda until 1912^[7] when he was convicted and jailed in Alor Star, Kedah until 1917. Two years later, he died in Alor Star.^[8] On 6 December 1934, Syed Mahmud's son Syed Hassan was, by a three to one vote, selected by the State Council as Bakal Raja or heir presumptive. However, Syed Hassan died on 18 October 1935.^[9]

On 30 April 1938, again by a three to one vote, the State Council chose Syed Putra (son of Syed Hassan) as the Bakal Raja. This choice was opposed by Syed Hamzah, the younger half-brother of Raja Syed Alwi and himself Vice-President of the State Council on the grounds that Syed Putra was too far removed from the throne under the Islamic inheritance laws (primogeniture did not then apply in Perlis). However, the British colonial rulers supported Syed Putra.^[10]

On the outbreak of the World War II, Raja Syed Alwi retreated to Kuala Kangsar, Perak. He returned to Perlis on 28 December 1941 but was already very ill and state affairs were exercised by Syed Hamzah.^[11] Syed Putra was at the time serving in the judiciary in Kuala Lumpur and had been advised by Sultan Musa Ghiatuddin Riayat Shah of Selangor to remain there. In May 1942, Syed Hamzah persuaded Raja Syed Alwi to withdraw Syed Putra's appointment as Bakal Raja and instead Syed Hamzah himself was appointed to that post. Raja Syed Alwi died in Arau on 1 February 1943 and a day later, before the funeral, Syed Hamzah was proclaimed fifth Raja of Perlis, by the consent of the Japanese Military Governor of Kedah and Perlis.^[12]

Syed Putra and his family stayed in Klang until 15 May 1942 when he returned to Perlis. He lived in a hut near the Arau railway station and received a $90 a month allowance from Raja Syed Alwi but this ceased on the latter's death.^[13] On 29 March 1945 he left for Kelantan, the home state of his consort Tengku Budriah, where he sold cakes and sundry goods for a living.^[14]

The British Military Administration (BMA) under Lord Louis Mountbatten refused to recognise Syed Hamzah as Raja. On 18 September 1945, Syed Hamzah abdicated.^[15][16] He went into exile in Thailand and died in Arau on 20 February 1958.^[17]

On 4 December 1945 the British proclaimed Syed Putra as sixth Raja of Perlis.^[18] He returned to Perlis from Kelantan, via Padang Besar. He was installed on 12 March 1949.^[19]

Raja Syed Putra objected to the Malayan Union treaty on the grounds that it contravened the 1930 British-Perlis Treaty giving governing power to the Raja-in-council. However, his protests that he signed under duress was rejected by the British. Subsequently, like all other Malay rulers, Raja Syed Putra repudiated the Malayan Union treaty.^[20]

Raja Syed Putra was elected Deputy Yang di-Pertuan Agong by the Malay rulers and served in that office from 14 April 1960 until the death of Sultan Hisamuddin Alam Shah on 1 September 1960.

Raja Syed Putra was elected as the third Yang di-Pertuan Agong of independent Malaya and served in that office from 21 September 1960. At 39 years and 301 days, he is the youngest Yang di-Pertuan Agong ever elected. He was installed at Istana Negara on 4 January 1961. On 16 September 1963 upon the proclamation of the Malaysian Federation comprising Malaya, British Borneo, Sarawak and Singapore, he became Yang di-Pertuan Agong of Malaysia. He completed his term in office on 20 September 1965. His son, Tuanku Syed Sirajuddin was elected as the 12th Yang di-Pertuan Agong and served from 2001 to 2006 after the death of the incumbent, Sultan Salahuddin Abdul Aziz Shah.

In September 1963, Malaysia was formed and Tuanku Syed Putra became known as the last King of Malaya before changed to Malaysia as he was first king under new federation and the only King of Malaysia that Singapore has ever had in modern history, as Singapore became an independent republic on August 9, 1965.

Raja Syed Putra's term of office as Yang di-Pertuan Agong was marked by the Indonesian Confrontation between newly created Malaysia and its larger neighbour, Indonesia. He offered to stay on as Yang di-Pertuan Agong at the end of his term, to see out the end of Confrontation, but this suggestion was rejected by then prime Minister Tunku Abdul Rahman.^[21]

As Yang di-Pertuan Agong, he instructed proper treatment of the royal regalia, which he believed was partly responsible for the mysterious final illness and death of Sultan Hisamuddin Alam Shah, his immediate predecessor.^[22]

Raja Syed Putra became the doyen of the Malay rulers, giving advice to more junior Rulers especially during the constitutional crisis with the then prime minister Mahathir Mohamad in 1983 and again in 1993.

He died at the National Heart Institute, Kuala Lumpur on 16 April 2000 from a heart attack. At that time, he was the longest reigning monarch in the world, a position he inherited from Franz Joseph II, Prince of Liechtenstein in 1989. He was buried at the Royal Mausoleum in Arau, Perlis.^[23]

Tuanku Syed Putra married twice:

1. in 1941 to Tengku Budriah binti Tengku Ismail (1924–2008) of the Patani Sultanate in Thailand. She served as his consort with the title of Raja Perempuan of Perlis and as Raja Permaisuri Agong. She is the mother of the current Raja of Perlis, Tuanku Syed Sirajuddin as well as five sons and five daughters.
2. in 1952 to Che Puan Mariam (née Riam Pessayanavin [th]; 23 April 1923–1986) by whom he had three sons and one daughter. She was a Thai Muslim from Bangkok and Miss Siam in 1939.^[24]
