The election of Bettino Craxi as PSI General Secretary marked, from 1976, a very important turning point in the history of Italian Socialism. His dynamic and charismatic leadership in fact contributed to a profound revision of its ideological seeds, the so-called scientific Marxism and, above all, to the recovery of the humanitarian and libertarian suggestions of pre-Marxist Socialism. This led to clear and definitive condemnation of the Marxist-Leninist model, which had found its practical realization in the Soviet system and in the countries beyond the Curtain, and prompted PSI to support the anti-Communist dissidence and establish strong relations with the Polish opposition and above all with Solidarność (the Solidarity movement). Craxi, both in the role of PSI General Secretary and as Italian Prime Minister, was able to provide it with a great politicaldiplomatic support and a lot of concrete help. To date, the history of these relations has not yet been adequately studied and this paper therefore aims to fill the gap.
