A British ship anchors off a small river mouth in January 1819. A few hundred Malays and a few dozen Chinese live there. Within five years the place will be a city, and its fate will be settled by men in a room in London.
The story
Stamford Raffles was a British official. He wanted a harbour on the route between India and China, and the Dutch already held most of the ports of the archipelago. He found Singapore: a deep natural harbour with fresh water, timber and a position on the main trade road.
When he arrived in January 1819, there was a small Malay settlement of about 150 people at the river mouth. The wider island may have had about 1,000. The local leader was Temenggong Abdul Rahman. Raffles had a problem: the island was under the Sultan of Johor, who was under Dutch influence. So he supported a rival claimant, Tengku Hussein, and proclaimed him sultan of Johor and Singapore. In return, the British were allowed to set up a trading post. Some Malay rulers did not accept this claim. Today historians still debate how fair that arrangement was.
The Dutch were furious. Talks in London lasted years. In March 1824 they signed the Anglo-Dutch Treaty. The Dutch gave up Melaka and agreed to Singapore being British. The British gave up their post at Bencoolen in Sumatra and agreed not to set up in the islands south of the Singapore Strait. In effect, the British took the peninsula, and the Dutch took the islands.
The line they drew later became the border between Malaysia and Indonesia. It also split the old Johor realm into Johor on the mainland and Riau-Lingga across the water. Over time, the Malay language grew into two main forms, Malaysian and Indonesian.
Singapore grew fast. In 1824 it had 10,683 people. Malays and Bugis were the largest group, and by 1826 the Chinese outnumbered the Malays (not counting Bugis and Javanese).
A treaty on paper changed daily life. Families, traders and rulers who had sailed freely between Singapore, Riau and Sumatra now lived under two different governments. The rulers of the old Johor realm were divided between a British and a Dutch sphere.
Where you can still see it today
- The Malaysia-Indonesia border, which follows the logic of the 1824 line.
- Two sister languages, Malay and Indonesian, that grew apart after the split.
- Melaka's old fort gate and Stadthuys, which passed from Dutch to British control.
What DNA can tell, and what it cannot
Families on both sides of the treaty line share deep island Southeast Asian roots. Families were split by a line drawn in an office, not by biology. A region estimate often cannot tell a person from one side from a person on the other.
DNA does not decide race, religion or bumiputera status.
