Sultan Alauddin Mahmud Syah I (died 1781) was the twenty-fifthsultan of Aceh in northernSumatra. He ruled from 1760 to 1781, although his reign was twice interrupted by usurpers (1764–1765, 1773).
Known in his youth as Tuanku Raja or Pocut Bangta, he was the son of the preceding SultanAlauddin Johan Syah and a lady from theAsahan Sultanate.[1] His father encountered internal opposition towards the end of his reign and died in August 1760. Tuanku Raja was proclaimed sultan under the name Alauddin Mahmud Syah. However, not all the regions heeded his claim. People from the XXII Mukims (one of the three regions orsagis of Aceh) held the prestigiousBaiturrahman Grand Mosque in the capital and opposed the new sultan. They were eventually driven out by force. It was only in December 1760 that all the threesagis agreed to acknowledge Alauddin Mahmud Syah. The most influential person at the court was Mantri Makota Raja, a scion of the sultan's family ofSiak Sri Indrapura who handled affairs on behalf of the young ruler.[2]
According to the account of the British navigatorThomas Forrest the sultan's relationship with theorang kayas (grandees) was poor during his first years. The sultan tried to control trade and circumcise the powers of theorang kaya.[3] This had worked during the heyday of the sultanate in the seventeenth century, but at this time it created internal instability. On the other hand, he had ambitions to expand the influence of Aceh along the west coast which had once belonged to the sultanate. Events in the mid-eighteenth century also gave an upswing to Aceh's economic role: TheBritish were established in the Sumatran portsNatal andTapanuli in 1751 and 1756 in order to support the pepper trade ofBengkulu. TheFrench also sought good relations with Aceh. The period therefore saw an increasing number of European ships and traders visiting the coast of Aceh. The ships often purchased pepper and other local products in local ports rather than via the capitalKutaraja.[4]
Disturbances broke out in 1763. The background was the inner tensions in the sultanate; the ruler tried to control commercial activities in the various parts of his kingdom without having the bureaucratic apparatus to implement this, which enraged the chiefs.[5] The uprising led to the expulsion of Alauddin Mahmud Syah in the following year. Mantri Makota Raja was made sultan under the nameBadr ul-Alam Syah. Alauddin Mahmud Syah escaped to Kota Musapi by the coast where he was assisted by a cleric,qadi Malik ul-Adil. With the help of the qadi he attacked Badr ul-Alam Syah and managed to kill him in August 1765. The sultan was thus restored in his dignity, although his position was considerably weakened. His elder sonMuhammad was later on married to the daughter of Badr ul-Alam Syah, apparently as an attempt of reconciliation between the political factions of Aceh.[6]
Alauddin Mahmud Syah remained undisturbed in his governance for some years. The British negotiated about trading conditions in 1767, 1771 and 1772–73, and found the sultan to be a weak and capricious type. Meanwhile, the Acehnesepanglima laut (sea commander) continued to expand the influence of the sultanate on the northern west coast. Some port towns were blockaded and theDutch garrison inBarus was attacked in 1771.[7] However, the inner cohesion of the state was once again declining. When Thomas Forrest returned to Aceh in 1772 he found an agitated situation. As he reported, discontent groups of people sometimes appeared threateningly outside the palace compound in the night. At this time the palace was guarded by a corps ofsepoys under anIndian fromCuddalore, which had been provided by the British inMadras. In April 1773 the XXII Mukims and XXV Mukims rose against him.[8] In his stead an official called Raja Udahna Lela was placed on the throne under the name SultanSulaiman Syah. However, he only lasted for two months before Alauddin Mahmud Syah returned with his adherents and expelled the usurper. After this he remained in power until his death in June 1781. There were suspicions that he may have been poisoned.[9] The sultan left two sons, Tuanku Muhammad and Tuanku Cut, of which the former succeeded him asAlauddin Muhammad Syah.[10]
