Aceh Sultanate - Later Years and Conquest By The Dutch

Later Years and Conquest By The Dutch

In the late 18th and early 19th Centuries, Koh Lay Huan – the first Kapitan Cina of Penang, had good contacts with the English-and-French-speaking Sultan of Aceh, Jauhar al-Alam. The Sultan allowed Koh to gather pepper plants in Aceh to begin pepper cultivation in Penang. Later, about 1819, Koh helped Sultan Jauhar al-Alam put down a rebellion by Acehnese territorial chiefs.

In the 1820s, as Aceh produced over half the world's supply of pepper, a new leader, Tuanku Ibrahim, was able to restore some authority to the Sultanate and gain control over the "pepper rajas" who were nominal vassals of the Sultan by playing them off against each other. He rose to power during the Sultanate of his brother, Muhammad Syah, and was able to dominate the reign of his successor Sulaiman Syah (r. 1838–1857), before taking the Sultanate himself, under the title Sultan Ali Alauddin Mansur Syah (1857–1870). He extended Aceh's effective control southward at just the time when the Dutch were consolidating their holdings northward.

Britain, heretofore guarding the independence of Aceh in order to keep it out of Dutch hands, re-evaluated its policy and concluded the Anglo-Dutch Treaty of Sumatra, which allowed for Dutch control throughout Sumatra in exchange for concessions in the Gold Coast and equal trading rights in northern Aceh. The treaty was tantamount to a declaration of war on Aceh, and the Aceh War followed soon after in 1873. As the Dutch prepared for war, Mahmud Syah (1870–1874) appealed for international help, but no one was willing or able to assist.

In 1874 the Sultan abandoned the capital, withdrawing to the hills, while the Dutch announced the annexation of Aceh. He eventually died of cholera, as did many combatants on both sides, but the Acehnese proclaimed a grandson of Tuanku Ibrahim Sultan. The local rulers of Acehnese ports nominally submitted to Dutch authority in order to avoid a blockade, but they used their income to support the resistance.

However, eventually many of them compromised with the Dutch, and the Dutch were able establish a fairly stable government in Aceh with their cooperation, and get the Sultan to surrender in 1903. After his death in 1907, no successor was named, but the resistance continued to fight for some time.
