In 1699 Sultan Badr al-alam Syarif Hasyim Jamal ad-din ascended to the throne, the first male to rule in almost 60 years. He was succeeded by several short-lived rulers, and in 1727 a member of the Buginese dynasty, Sultan Ala ad-din Ahmad Shah took power. 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.
