The essay is about the history of Afi, the Italian Women Alliance for equality and peace, that was chaired by Teresita Sandesky Scelba, from 1944 to 1950. Afi is a femminist, independent, peaceful and internationalist organization. The author analyzes the organization’s structure, its relation with communist and catholic women and the connections with political parties and mass organizations. A great attention is devoted to the contribution made by Afi to the movement for the abolition of prostitution and the development of the law against State sponsored prostitution. The law was presented to the Italian Senate by the socialist representative Lina Merlin in 1948.
