In 1819, Thomas Stamford Raffles arrived and signed a treaty with Sultan Hussein Shah of Johor, on behalf of the British East India Company, to develop the southern part of Singapore as a British trading post. In 1824, the entire island became a British possession under a further treaty with the Sultan, as well as the Temenggong.[15] In 1826, Singapore became part of the Straits Settlements, under the jurisdiction of British India, becoming the regional capital in 1836.[
