The Johor Sultanate (Malay: Kesultanan Johor or کسلطانن جوهر; also called the Sultanate of Johor, Johor-Pahang-Riau-Lingga, or the Johor Empire) was founded by Sultan of Malacca Mahmud Shah's son, Alauddin Riayat Shah II in 1528.
Prior to being a sultanate of its own right, Johor had been part of the Malaccan Sultanate before the Portuguese captured its capital in 1511. At its height, the sultanate controlled territory in what is now modern-day Johor, Pahang, Terengganu, territories stretching from the rivers of Klang to the Linggi and Tanjung Tuan, situated respectively in Selangor, Negeri Sembilan and Malacca (as an exclave), Singapore, Pulau Tinggi and other islands off the east coast of the Malay Peninsula, the Karimun Islands, the islands of Bintan, Bulang, Lingga and Bunguran, and Bengkalis, Kampar and Siak in Sumatra.
