In the 1951 Denmark, the colonial master over Greenland, decided to remove a group of 22 intelligent Inuit children from their families and relocate them to Denmark for re-education. The children were first quarantined and then placed in foster families. The next year part of them were returned to Greenland but they were placed instead of their homes to an orphanage where they were not allowed to use their mother tongue. Instead of becoming some new wonderful breed of citizens many of the subjects became alcoholics and died young. NGOs "Save the Children Denmark" and "Danish Red Cross" played a part in and Denmark has not apologized for this experiment.
