Johor Sultanate
Alauddin Riayat Shah II, a son of Mahmud Shah, established the Johor Sultanate in 1528. Former-Malaccan territories were quickly brought under Johor's influence, including Bintan, where an important trading port called Bandar Riau was opened. As it prospered and a war with the Jambi Sultanate threatened Johor in 1722, the capital was moved to Riau, which became a centre of trade and Islamic studies much as Malacca had been.
