Raja Tua (Tungku Tuha) was styled Sultan Mukaddam Shah when he became the sultan in 1603 and resided in Bota Kanan. He was the son of a female relation (?sister) to Almarhum Sultan Ahmad Tajuddin and Almarhum Sultan Tajul Ariffin, and grandson of Almarhum Sultan Mansur Shah I. According to oral history handed down over the generations, Sultan Mukaddam Shah had a beautiful daughter named Puteri Limau Purut. As it was customary in those days, she was bethrothed since childhood to a relative named Raja Mansur. When the Sultan of Acheh asked for her hand in marriage, the request was refused.
In retaliation, the Sultan of Acheh attacked Perak, landing at Bota Kanan at midnight. Perak was taken completely by surprise. Acheh carried off the Sultan of Perak and his entire family, including Puteri Limau Purut and her chaperone, Che Esah Gerbang.
The Perak chiefs sent for Bendahara Garang Megat Menjanas, Megat Iskandar and his two brothers. Raja Mansur who at that time stationed at Intan was also called. It was decided to send the Bendahara Garang and his party to Acheh to negotiate for the safe return of the Perak royal family and Raja Mansur to hold the fort during the sultan’s absence.
The Bendahara Garang was successful. He brought Puteri Limau Purut and the others back but Sultan Mukaddam Shah mangkat in Acheh. He was interred in Acheh and was later known as Marhum Hilang Di-Acheh.
As described by Jeragan Abdul Shukor in List of Graveyards of the Late Sultans of the State of Perak (R.A. Soc. No.48, 1907.). In his report, Almarhum Sultan Idris Shah I had described Sultan Mukaddam Shah as the grandson of Almarhum Sultan Mansur Shah I.
Wikipedia lists Sultan Mukaddam Shah as a son to Sultan Ahmad Tajuddin.
Probably the 12th Sultan of Acheh, Sultan Iskandar Muda, who reigned from 1607 till 1636.
