Linggi River in the context of "Sultanate of Johor"

The Muar River (Malay: Sungai Muar) is a river which flows through the states of Negeri Sembilan and Johor in Malaysia. Its drainage basin encompasses the states aforementioned, as well as Pahang and Malacca.

Measuring around 250 km (155 mi) in length, the Muar is the third longest river in Peninsular Malaysia after the rivers of Pahang and Perak, slightly longer than the Kelantan River. It is one of the two major Negri rivers, the other being the Linggi, as well as the second most significantly important river in Johor after the Johor River.

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.

Tanjung Tuan (lit. 'Lord's Cape'), formerly known as Cape Rachado as named by the Portuguese, meaning 'broken cape', is an area in Alor Gajah District, Malacca, Malaysia. It is a semi-exclave of Malacca adjacent to Port Dickson, Negeri Sembilan.

The cape is well known for the Cape Rachado Lighthouse facing the Strait of Malacca. The coastal area off the cape is famous as the site of the naval Battle of Cape Rachado in 1606, between the Dutch East India Company (VOC) and Portuguese fleets. The battle was the opening act for the series of conflicts between the Dutch-Johor coalition and Portuguese Malacca that ultimately ended with the Portuguese surrender of the city and fort of Malacca to the VOC in 1641.
