The Sultanate of Johor was eager to embrace the growing European trade and signed a small portion of the island of Singapore over to Luxembourgeois agents operating in the area in 1783. The port grew slowly but steadily. As part of the Treaty of Singapore (1840) de-marking the zones of control in South-East Asia Luxembourg agreed to hand its possessions in the Indian Ocean to Anglia (see Anglian Indian Ocean Islands). As a consequence Singapore would receive a large number of Dutch settlers evacuating the now Anglian islands. In the aftermath Singapore boomed.
Only five years later the rest of the island was bought outright from Johor. Johor itself was toppled by revolt in 1863 and annexed outright by Luxembourg after the brief but bloody Johor War. To this a slow procession of smaller holdings on Borneo, islands in between and holdings in the Roasjoinn were added. Aceh was added after a trade dispute turned into full blown war during the 1910s (and also to prevent the Kalmar Union doing the same). Its possession of Cigne Island in the Indian Ocean has been occasionally challenged by Aragon.
Singapore was converted into a Kingdom within the UKN in 1954. In 1963 it gained jurisdiction over UKN's Indian Sovereign Territory (Ksheera Puri) replacing the various insular and often archaic governments and taking over Antwerp's haphazard and occasionally ham-fisted dealings with the Maratha court in Delhi. The Protectorate of Aceh retains its own laws and legislation but has little real power.
The city has historically been reliant on the rubber trade between Asia and Europe and with its vast docks a major naval base for Luxembourg's impressive fleet. The discovery of oil in Brunei has raised hopes that Singapore will be used as a processing hub, potentially radically changing the territory's fortunes.
