Why the Netherlands clung to a remote Pacific territory long after losing its empire.

In short: When Indonesia gained independence in 1949, the Dutch refused to surrender the western half of New Guinea. For over a decade, they attempted to build a separate nation there, hoping to provide a homeland for displaced Eurasians and a final foothold for their fading colonial influence in the Pacific.

The Dutch claim to New Guinea originated from a 1660 treaty recognizing the Sultanate of Tidore's influence over the region, which the Netherlands later used to justify their own sovereignty. By 1898, the Dutch had established administrative outposts at Fakfak and Manokwari to preempt British and German expansion. However, the territory remained largely ignored until the mid-20th century, when it became a central point of contention in the decolonization of the Dutch East Indies.

Following the 1946 Linggadjati Agreement, the Dutch unilaterally amended the terms to exclude New Guinea from the transfer of sovereignty to Indonesia. Driven by domestic political pressure and the desire to create a 'tropical Holland' for Eurasians who had been sidelined in the new Indonesian state, the Dutch began investing in the territory. They appointed Stephan Lucien Joseph van Waardenburg as the first Governor in 1950 and accelerated efforts to build local institutions, including a naval academy and the New Guinea Council, which officially took office in 1961.

Tensions escalated as Indonesia, under President Sukarno, viewed the territory as an integral part of its natural borders. The dispute turned into a low-level military conflict by 1962, marked by the Vlakke Hoek incident where Dutch forces defeated an Indonesian naval infiltration. Despite these tactical successes, the Netherlands faced mounting diplomatic pressure from the United States and waning domestic support. In August 1962, the Dutch agreed to the Bunker Proposal, transferring the territory to United Nations administration before it was handed to Indonesia in 1963. The final status was confirmed by the 1969 Act of Free Choice, a plebiscite whose fairness remains a subject of significant historical dispute.
