After the restoration of Austrian government in Venice he fled to Switzerland where, in 1850, he became friends with Giuseppe Mazzini. The two collaborated on the newspaper L'Italia del Popolo. Mazzini also made use of his legal expertise in financial transactions, commissioning him to organize an international loan to support the Italian cause. The Swiss authorities became concerned about their country's neutrality vis-a-vis the neighboring Austrian Empire, revoked Varè's asylum and expelled him with a decree of 26 February 1851. He moved to Genoa, where he collaborated again with Mazzini on the newspaper Italia e Popolo. Soon the authorities there also opposed his stay and in September 1851 he moved to Turin.[3][5]
After this he moved away from Mazzini and the radical nationalists, opposing the uprising in Genoa in June 1857, though he was briefly interned as a suspect along with his friend it:Domenico Giuriati.[3]
