Johor Sultanate
Based at Pekan Tua, Sungai Telur, Johor, the Johor Sultanate was founded by Raja Ali Ibni Sultan Mahmud Melaka, known as Sultan Alauddin Riayat Shah II (1528–1564), in 1528. Although Sultan Alauddin Riayat Shah and his successor had to contend with attacks by the Portuguese in Malacca and by the Acehnese in Sumatra, they managed to maintain their hold on the Johor Sultanate.
