The Nazis aimed to define strict gender roles for women in order to promote their goal of increasing the Aryan population and building a Thousand Year Reich. They wanted women to focus on marriage, childrearing and supporting their husbands. To encourage this, the Nazis provided incentives like marriage loans and the Mother's Cross medal for large families, while restricting women's access to education and careers. However, the Nazis' attempts to control women and increase the birth rate through these policies were only partially successful.
