The move, which allows Greenland to gradually take responsibility over areas like criminal justice and oil exploration, follows a referendum last year in which 76 percent of voters said they wanted self-rule. Many of the changes are deeply symbolic. Kalaallisut, a traditional Inuit dialect, is now the country’s official language, and Greenlanders are now recognized under international law as a separate people from Danes.

Thrillingly, the Greenlandic government now gets to call itself by its Inuit name, Naalakkersuisut — the first time in history, officials said, that the word has been used in a Danish government document.
