This led to the partition of Johor-Riau under the Anglo-Dutch treaty of 1824, by which the region north of the Singapore Strait including the island of Singapore and Johor were to be under British influence, while the south of the strait along with Riau and Lingga were to be controlled by the Dutch. By installing two sultans from the same kingdom, both the British and the Dutch effectively destroyed the Johor-Riau polity and satisfied their colonial ambitions. Under the treaty, Tengku Abdul Rahman was crowned as the Sultan of Riau-Lingga, bearing the name of Sultan Abdul Rahman, with the royal seat in Daik, Lingga. Tengku Hussein, backed by the British, was installed as the Sultan of Johore and ruled over Singapore and the Peninsular Johor. He later ceded Singapore to the British in return for their support during the dispute. Both sultans of Johor and Riau acted mainly as Puppet monarchs under the guidance of the colonial powers.
