The Acehnese sultan Ali Ri'ayat Syah I attacked and defeated the tin-producing Malay kingdom Perak in 1573.

He ordered his uleëbalangs (chiefs) to grow a beard and wear jubba and turban - in other words to dress Arabic.

The enterprise was a stage in the triangular fight between Aceh, Johore and the Portuguese which enabled the last-mentioned to hold out.

According to a French account the murderer was a fisherman who had risen in the ranks of the kingdom through his military courage; this person later became sultan of Aceh under the name Alauddin Ri'ayat Syah Sayyid al-Mukammal.

[6] The murdered ruler left a young grandson, Raja Asyem, born from his daughter and the Johor sultan Ali Jalla Abdul Jalil Shah II.
