Perkasa Alam Syarif Lamtui

Perkasa Alam Syarif Lamtui or Badr ul-Alam Syarif Lamtui ul-Mutaawi Jamal ul-Lail (died after 1712) was the nineteenth sultan of Aceh in northern Sumatra and ruled briefly in 1702–1703.

Perkasa Alam was the son of an Arab of sayyid ancestry, Ibrahim Jamal ul-Lail. A somewhat doubtful source mentions him as the nephew of a previous ruler, Sultana Kamalat Syah (r. 1688–1699). When his older brother Badr ul-Alam Syarif Hasyim Jamaluddin abdicated in 1702 a short interregnum followed. It was only after Badr ul-Alam's death in the same year that the parties agreed to enthrone Perkasa Alam.

He was not long on the throne, however. In order to improve the financial position of the court he introduced new taxes and reimposed duties on British traders. The Britons present in Aceh asked for exemption which was refused. British ships then blockaded the port and fired on villages situated at the estuary of the Aceh River. Meanwhile the orang kayas (grandees) and uleëbalangs (chiefs) were dissatisfied with the new levies imposed on the land. Taking advantage of the beleaguered situation of Perkasa Alam they launched a revolt. A son of his predecessor, Alauddin, secured his deposition in June 1703. Two months later he ascended the throne under the title Jamal ul-Alam Badr ul-Munir. Perkasa Alam later stayed in the village Pasanga on the east coast of Aceh. In 1712 he was attacked and expelled by 7,000 troops dispatched by Jamal ul-Alam Badr ul-Munir. He was eventually captured in Tranigain and seems to have been kept in captivity by the new ruler.
