Bongsu controlled the settlement of Kota Seberang which was located almost straight across the Johor River from the royal administrative center and capital Batu Sawar. He is also said to have controlled areas around the Sambas River on the island of Borneo. In 1613, Raja Bongsu was one of the prisoners taken back to Aceh after the invasion of Johor by sultan Iskandar Muda. He was married to one of Iskandar's sisters, and returned to Johor as the new sultan. Raja Bongsu was subsequently enthroned as Abdullah Ma'ayat Shah of Johor. His half-brother Alauddin Riayat Shah III who had fallen from power at the time of Iskandar Muda's offensive on Johor in 1613 had fled to Lingga and probably died there in or around 1615. In 1618, Abdullah Ma'ayat Shah moved to Lingga and gained the support of Orang Laut and the Dutch to wage a war against Aceh. He later divorced his wife who was also a sister of Iskandar Muda, a move that further angered the sultan. He spent most of his reign as a wanderer, pursued from town to town and island to island by the Acehnese. He died at Tambelan archipelago in March 1623.
