To help increase the numbers of Aryans, the Nazis set up special homes called "Lebensborn". These were for unmarried pregnant woman who were likely to have children that had Nordic or Aryan qualities. This mainly meant fair skin, blond hair, blue eyes. Though slight differences could still be considered Aryan as lots of people in Germany at the time had dark hair and eyes. Heinrich Himmler believed that this would help create more members of the master race. He arranged for nine Lebensborn homes to be built in Germany, and another ten in Norway. There were also Lebensborn in France, Belgium and Luxembourg. About 20,000 children were born in these homes during the Third Reich.
