The king from Gombroon

According to At-Tarikh Salasilah Negeri Kedah, written by Muhammad Hassan bin Dato' Kerani Muhammad Arshad in 1928, in about 630 CE, Maharaja Derbar Raja of Gombroon (now known as Bandar Abbas) in Persia was defeated in battle and escaped to Sri Lanka, and was later blown off course by a storm to the remote shores of Kuala Sungai Qilah, Kedah.^[6] The inhabitants of Kedah found him to be a valiant and intelligent person and made him the king of Kedah. In 634 CE, a new kingdom was formed in Kedah consisting of Persian royalty and native Malay people of Hindu faith; the capital was Langkasuka.^[6]

Conversion to Islam

Based on the account given in Hikayat Merong Mahawangsa (also known as the Kedah Annals), the Sultanate of Kedah was formed when King Phra Ong Mahawangsa converted to Islam and adopted the name Sultan Mudzafar Shah. At-Tarikh Salasilah Negeri Kedah described the conversion to Islamic faith as starting in 1136 AD. However, historian Richard Winstedt, quoting an Acehnese account, gave a date of 1474 for the year of conversion to Islam by the ruler of Kedah. This later date accords with an account in the Malay Annals, which describes a raja of Kedah visiting Malacca during the reign of its last sultan seeking the honour of the royal band that marks the sovereignty of a Malay Muslim ruler. The request by Kedah was in response to be Malacca's vassal, probably due to fears of Ayutthayan aggression.^[7]

British colonisation of Penang and Seberang Perai

The first British vessel arrived in Kedah in 1592.^[8] In 1770, Francis Light was instructed by the British East India Company (BEIC) to take Penang from Kedah. He achieved this by assuring Sultan Muhammad Jiwa Zainal Adilin II that his army would protect Kedah from any Siamese invasion. In return, the sultan agreed to hand over Penang to the British. In 1786, Light negotiated with the new sultan of Kedah, Abdullah Mukarram Shah, over the cession of Penang to the BEIC.^[9][10] However, Light made the agreement without the consent of his superiors in India. The BEIC did not provide military support, as promised by Light, when Siam attacked Kedah. The sultan demanded that Light return Penang, but Light was reluctant to hand it back. He offered compensation for the damage but was refused by the sultan. In 1790, Abdullah planned to launch an amphibious invasion of the island of Penang to recapture it. The BEIC with the help of the British military made a preemptive strike and attacked Kedah's navy and fort in Seberang Perai, damaging them. The sultan signed a ceasefire agreement with Light in 1791.

On 7 July 1800, while George Alexander William Leith was Lieutenant-Governor of Penang, a treaty came into effect that gave the British sovereignty over Seberang Perai, subsequently named Province Wellesley. The treaty, negotiated by Penang's First Assistant George Caunter and Sultan of Kedah Dziaddin Mukarram Shah II, increased the annual payment to the sultan from 6,000 to 10,000 Spanish dollars per annum.^[11] While the acquisition improved Penang Island's military and food security, for Kedah it provided a protective strip against enemy attack from the sea.^[12] The treaty also provided for the free flow of food and commodities from Kedah to Penang Island and Province Wellesley.^[13] To this day, the Malaysian federal government still pays Kedah, on behalf of Penang, RM 10,000 annually as a symbolic gesture.^[14]

Partition of Kedah

After the death of Sultan Abdullah Mukarram Shah in 1797, the throne was given to his half brother Sultan Dziaddin Mukarram Shah II. However Sultan Dziaddin was forced to abdicate in 1803 by the king of Siam and was replaced by his nephew Sultan Ahmad Tajuddin II. This sparked a succession crisis as crown prince, Tunku Bisnu claimed to be the rightful heir to the throne. Fearing civil war, the Siamese kingdom reconciled the two parties by appointing Tunku Bisnu as ruler of Setul, thus establishing the Kingdom of Setul Mambang Segara in 1808.^[15]

From 1821, a Siamese invasion of Kedah brought much dislocation to the region and territories within Kedah were broken up. This period marked the exile of Sultan Ahmad Tajuddin Halim Shah II^[16] and the imposition of direct Siamese rule on Kedah for a time. Tengku Kudin, a nephew of Sultan Ahmad Tajuddin, captured Alor Setar from the Siamese in 1831^[17] but the town was retaken soon after. After 20 years of living in exile, Sultan Ahmad Tajuddin was restored to the Kedah throne in 1842.

In 1892, the kingdom was reunified with the Kedah Sultanate. However, the assimilation of the Siamese people and their culture in Setul had weakened Kedah rule over it. The Anglo-Siamese Treaty in 1909 finally ended Kedah rule over Setul, as the Siamese and British agreed to exclude Setul from Kedah jurisdiction, thus separating Kedah and Setul.

Islamic era

Sultan of Kedah
Provincial
Incumbent
Sallehuddin since 12 September 2017
installation 22 October 2018
Details
Style	His Royal Highness
Heir apparent	Tunku Sarafuddin Badlishah
First monarch	Mudzaffar Shah I (first)
Formation	1136 (1136)
Residence	Istana Anak Bukit, Alor Setar

The beginning of the use of the title sultan in Kedah is attributed to a visit by a Muslim scholar from Yemen, Sheikh Abdullah bin Ja'afar Quamiri, to Durbar Raja II's palace at Bukit Meriam in 1136. The audience resulted in the king's conversion to Islam. He adopted the name Mudzaffar Shah and established the sultanate of Kedah.^[18]

The source for the list of sultans given here is the official genealogy given for the sultan of Kedah.^[21] There are however discrepancies with the Kedah Annals as it lists only five sultans from the first convert Mudzaffar Shah to Sulaiman Shah, who was captured by Aceh in 1619, in contrast to the twelve listed here. The rest of the list largely follows as that given in the Kedah Annals with the exception of a few changes and more recent updates in the 20th and 21st century.^[22]

Nobat

The nobat musical instruments of Nagara and Nepiri were introduced to Kedah by Maharaja Derbar Raja. The instrument is also called semambu. The band is led by the king, and it consists of drums, a gong, a flute and a trumpet. Today, nobat is a royal orchestra, played only during royal ceremonies such as inaugurations, weddings, and funerals. The building which houses the instruments and where the ensemble rehearses is known as the Balai Nobat, literally the Office of Nobat, in Alor Setar city proper.^[6]
