Mischling was a pejorative legal term which was used in Nazi Germany to denote persons of mixed "Aryan" and non-Aryan, such as Jewish, ancestry as they were classified by the Nuremberg racial laws of 1935. In German, the word has the general denotation of hybrid, mongrel, or half-breed. Outside its use in official Nazi terminology, the term Mischlingskinder was later used to refer to war babies born to non-white soldiers and German mothers in the aftermath of World War II.

Brown Babies is a term used for children born to black soldiers and white women during and after the Second World War. Other names include "war babies" and "occupation babies." In Germany they were known as Mischlingskinder, a term first used under the Nazi regime for children of mixed Jewish-German parentage. As of 1955, African-American soldiers had fathered about 5,000 children in the American Zone of Occupied Germany. In Occupied Austria, estimates of children born to Austrian women and Allied soldiers ranged between 8,000 and 30,000, perhaps 500 of them biracial. In the United Kingdom, West Indian members of the British military, as well as African-American soldiers in the US Army, fathered 2,000 children during and after the war. A much smaller and unknown number, probably in the low hundreds, was born in the Netherlands, but the lives of some have been followed into their old age and it is possible to have a better understanding of the experience that would unfold for all of the Brown Babies of World War II Europe.
