Nazi Germany didn't just seek to eradicate those who didn't meet the criteria of their ideal race. They also fought to create a super genetic line through selective breeding in the ultra-secret, undeniably twisted Lebensborn program. It was akin to Josef Mengele's concentration camp experiments to the extent that it involved Nazi "science" and a total lack of bioethics.

This program, created by the SS, was a state-supported, registered association sparked by the shrinking birth rate in Nazi Germany. Lebensborn mothers faced a moral predicament. While many already were fervent followers of Hitler, for some, it was a matter of survival in war-torn, Nazi-occupied Europe.

The Lebensborn program attempted to breed racial purity through a very specific set of phenotypic criteria. The children of Lebensborn were often kidnapped from their Nordic and Eastern European families, forced to erase their past identities and be reborn as Hitler youth. For many, their lives were lies, and they only discovered their origins in adulthood, if at all.

Here's a look inside the twisted Nazi program to breed a master race and what happened to the Lebensborn survivors when the war was finally over.
