Pahang (Malay pronunciation: [paˈhaŋ]; Pahang Hulu Malay: Paha, Pahang Hilir Malay: Pahaeng, Ulu Tembeling Malay: Pahaq), officially Pahang Darul Makmur with the Arabic honorific Darul Makmur ("The Abode of Tranquility") is a sultanate and a federal state of Malaysia. It is the third largest state in the country and the largest state in Peninsular Malaysia, and the ninth most populous. The state occupies the basin of the Pahang River, and a stretch of the east coast as far south as Endau. The state borders the Malaysian states of Kelantan and Terengganu to the north, Perak, Selangor and Negeri Sembilan to the west and Johor to the south, with the South China Sea is to the east. Pahang is separated from the west coast states by the Titiwangsa Mountains that forms a natural divider between the peninsula's east and west coasts from north to south, and from Terengganu in the east by the Pantai Timur Range. The state's highest elevation culminates at Mount Tahan in the eponymous Tahan Range, which is 2,187 metres (7,175 ft) high. Although two thirds of the state is covered by dense rain forest, its central plains are intersected by numerous rivers, and along the coast there is a 32-kilometre (20 mi) wide expanse of alluvial soil that includes the deltas and estuarine plains of the Kuantan, Pahang, Rompin, Endau, and Mersing Rivers.
The state is divided into 11 districts (daerah) – Pekan, Rompin, Maran, Temerloh, Jerantut, Bentong, Raub, Lipis, Cameron Highlands and Bera. The largest district is Jerantut, which is the main gateway to the Taman Negara national park. Pahang's capital and largest city, Kuantan, is the eighth largest urban area by population in Malaysia. The royal capital and the official seat of the Sultan of Pahang is located at Pekan. Pekan was also the old state capital and its name translates literally into 'the town', it was known historically as 'Inderapura'. Other major towns include Temerloh, Raub, Bentong, Jerantut, Kuala Lipis and its hill resorts of Genting Highlands, Bukit Tinggi, and Cameron Highlands. The head of state is the Sultan of Pahang, while the head of government is the Menteri Besar. The government system is closely modelled on the Westminster parliamentary system. The state religion of Pahang is Islam, but allows other religions in its territory.
