She managed to convince Wilfried Maaß to have a similar "Manifesto of the 374" published in the Stern. Appearing on 6 June 1971 under the heading Wir haben abgetrieben! (We have had abortions) and signed by prominent figures such as the actress Romy Schneider, it was immediately effective, causing pro-abortion pressure groups to be created throughout the country.[36][37] The Aktion 218 campaign, a reference to the section of the criminal code which banned abortion, was instigated by students in Munich, Cologne, Frankfurt and West Berlin.[36][37] A public display on the topic of abortion was at a rally held by various groups in November 1971 in Düsseldorf, where it gained mass support.[31]
