She moved to Belgium, where she supported anarchist prisoners in Brussels and led the campaign in defense of Sacco and Vanzetti, but was eventually forced to leave the country due to a police investigation of her.
[2] In the wake of the March on Rome and the rise of Italian fascism, in 1923, Zazzi left Italy and moved to Paris, where she supported her recently bereaved brother and his newborn baby.
[5] An energetic activist, she dedicated herself to aiding fellow refugees from Italy and distributing anarchist propaganda, working closely together with the family of Camillo Berneri.
She also led the local campaign in defense of the Italian-American anarchists Sacco and Vanzetti, culminating with the spontaneous organisation of a general strike on the day of their execution.
[8] Immediately after the Spanish Civil War broke out in July 1936, Malaguti travelled to Barcelona and joined the Ascaso Column, going on to fight in the Battle of Monte Pelado.
[11] But Zazzi ended up feeling disappointed by the culture of the Italian resistance, finding herself missing the camaradery of the movements in France, Belgium and Spain.
[10] When Malaguti died a decade after the end of the war,[1] Zazzi began a relationship with Alfonso Fantazzini,[2] a former partisan that she had met during her exile in Western Europe.
The couple frequently hosted meetings of the local anarchist movement, for whom they were the last representatives of the old anti-fascist generation, and provided room to people that had moved to the city from Southern Italy.
[12] She was also a mentor to her partner's son Horst Fantazzini, who went on to become famous as a bank robber, and was active in the campaign for the acquittal of Pietro Valpreda.
