When did lebensborn happen?

Lebensborn was a program initiated by the Nazi regime in Germany in 1935, aimed at promoting the growth of the Aryan population through the establishment of maternity homes and the encouragement of racially "pure" births. It continued until the end of World War II in 1945. The program sought to support the breeding of "racially valuable" children, often involving the forced separation of children from their parents and the kidnapping of children from occupied territories deemed to fit the Aryan ideal.
