سلطنة جوهر
On 17 March 1824, the United Kingdom and the Netherlands signed the Anglo–Dutch Treaty of 1824. It divided the old Johor Sultanate into two new Sultanates: the new Sultanate of Johor, which would be under the British sphere of influence, and the Sultanate of Riau–Lingga under Dutch influence. Under Article XII of the Treaty, Britain agreed that "no British Establishment shall be made on the Carimon Isles, or on the Island of Bantam, Bintang, Lingin, or on any of the other Islands South of the Straits of Singapore ..." The islands and islets within the Straits fell within the British sphere of influence. This included Pedra Branca, which thus remained part of the territorial domain of the new Johor Sultanate.
