On June 21, 2009, the world’s largest island quietly changed its legal status. Greenland’s Self-Government Act took effect, replacing the Home Rule arrangement established in 1979. The date was chosen deliberately: it was the summer solstice, the longest day, and the national day of the Inuit territory. In Nuuk, the capital, Queen Margrethe II of Denmark signed the proclamation. The ceremony featured drum dancing and speeches in Kalaallisut, the Greenlandic language, which now became the sole official language.
The act transferred control of the police, courts, and coast guard from Copenhagen to Nuuk. Crucially, it granted Greenlanders rights to their subsurface resources, including potentially vast reserves of oil, gas, and minerals. Revenue from these resources would allow a reduction of the annual block grant from Denmark, a step toward eventual economic independence. Foreign policy and defense remained with the Danish government. The shift was not a violent secession but a meticulously negotiated devolution, passed by the Danish parliament with overwhelming support.
This event is frequently misunderstood as a sudden lurch toward independence. It was, in fact, the latest step in a gradual process that began in 1953 when Greenland ceased being a colony. The self-rule agreement was ratified by 75% of Greenlandic voters in a 2008 referendum. The model is one of incremental sovereignty, where political autonomy expands in lockstep with economic capability. It is a deliberate, legal unwinding of a colonial relationship.
The long-term impact remains an open question. The self-rule agreement contains a pathway to full independence, contingent on a popular vote. Climate change, by opening new shipping routes and access to resources, has accelerated the geopolitical significance of Greenland. The 2009 act positioned the island’s government, not a foreign capital, to make the critical decisions about who develops those resources and under what terms. It transformed Greenland from a remote dependency into a nascent nation-state with agency over its own future.
