The book contains a selections of the contributions presented during the conference Amintore Fanfani e Guido de Marco: due statisti mediterranei alla Presidenza dell'assemblea Generale delle Nazioni Unite (New York, Casa Italiana Zerilli Marim - New York University), which took place the 26th of September 2011 in the occasion of the centenary of Fanfani's birth. The aim of this volume is to remember the commitment of Fanfani as President of the twentieth session of the United Nations General Assembly (1965-66), highlighting his effort in pointing out questions of foreign politics in Italy. As Franco Ciavattini writes in the preface, Fanfani was particularly able to "adjust the political-diplomatic profile of Italy, stressing the autonomy of the Holy See and tracing a less ideological anticommunism" and also to balance a national "neoatlantic" policy with an openness to African, Asiatic and especially Arabian countries.
