Olga Eggers (1875-1945) is one of the great mysteries in modern Danish political history. She was a beloved author of progressive novels for women and children, a Social Democrat and an advocate for sexual liberation and women's rights, who surprised everyone with a sudden commitment to the National Socialist cause in 1934. Her political engagement soon became one-sidedly fixed on anti-Semitism, cultivating a belief in a global Jewish conspiracy. As editor of the notorious anti-Semitic tabloid Kamptegnet (The Battle Cry), she denounced modernism as hypocritical and misogynistic and promoted a conservative concept of biological gender differences, restricting women to roles as wives and mothers. Paradoxically, although National Socialism did not ideologically endorse political and public roles for women, individual women such as Eggers did achieve pivotal status in local National Socialist movements. Yet her political career soon faded, as she was prosecuted and convicted for libel in 1943, and she died few days after the liberation of Denmark in May 1945.
