Greenland documentary forces Danes to confront their colonial heritage

As Donald Trump threatens to take over the territory, film claims its cryolite mine was plundered by Denmark

For two weeks in Denmark the subject of the documentary was bigger than Trump", says producer Michael Bevort. The broadcast of Gronlands hvide guld (Greenland's white gold), a 55-minute film about the Danish exploitation over several decades of a cryolite mine in southern Greenland and the vast sums of money it generated, made waves in February in both Greenland and its former colonial ruler, Denmark. But the reaction between the two could not have been more polarised.

In Greenland, which remains part of the Danish kingdom, with Denmark still controlling its foreign and defence policies, there were feelings of anger and deep sadness. The country was in the middle of an election being watched by the world thanks to Donald Trump's threats to take control of the Arctic island. According to a poll for Greenlandic newspaper Sermitsiaq, more than a third of voters said the documentary would influence their vote.
