In the 1960s, the PR launched the Italian League for Divorce (
Lega Italiana per il Divorzio, LID), which succeeded in marshalling together the secular parties into a unified political alliance and getting the law on divorce approved. During the 1970s, the PR helped launch the Women's Liberation Movement (
Movimento di Liberazione della Donna, MLD) by supporting the activities of the Italian Centre for Sterilisation and Abortion (
Centro Italiano Sterilizzazioni e Aborti, CISA) and by giving its support to the Italian Revolutionary Homosexual United Front (
Fronte Unitario Omosessuale Rivoluzionario Italiano, FUORI), one of the first Italian
homosexual associations. All the aforementioned groups, as well as many others, were part of a Radical movement that was organised as a federation of single-issue associations rather than a united party. The Italian League for Divorce developed a broad following with the
1974 referendum to repeal the Divorce Law which had been passed three years prior. The referendum was initiated by
Gabrio Lombardi with the support of the Christian Church as a form of reactionary opposition to legal divorce. The campaign for a no vote, in opposition to the Christian Democrats, was mostly led by unofficial party leader Marco Pannella, who was a fierce champion for the rights of woman. This led to further connections with left-wing groups within Italy at the time such as the
Italian Socialist Party and the
Italian Communist Party. Because of the enormous campaigning effort done by Pannella, the divorce referendum resulted in around 60% of citizens voting in favour of protecting divorce laws, and this was considered to be largely to the credit of Radical Party, which emboldened the LID. The PR found its first connections to
Fuori! in the 1970s when
Angelo Pezzana, a member of the Radical Party and one of the founders of the Italian Revolutionary Homosexual United Front, had attempted to further politicise the association and connect it with the party. In 1974, at the 14th congress of the Radical Party, Fuori! was officially federated as a part of the Radical Party, resulting in the dissatisfaction and withdrawal of some Fuori! members, such as
Mario Mieli. By the 15th congress, which took place in 1976, Fuori! had announced a list of candidates to run for positions within the party, thus marking the first time in which Italy had openly homosexual citizens run as candidates within a party elections, and by 1979, Angelo Pezzana became a member of the Italian parliament. Pezzana was in office for less than a month before retirement, but continued to write on his experiences on the advancement of Italian homosexual rights, as facilitated by the Radical Party. Considered an early example of a political party placing importance on
environmentalist issues, from 1972 onwards the PR also formed environmental organisations, including the
Friends of the Earth's Italian chapter, the League Against Vivisection and League Against Hunting. == Popular support ==
