In August 1874 Zanardelli participated in the
Geneva conference of the Universal League of Workers Guilds. He then settled in
Lugano. With
Lodovico Nabruzzi he was one of the main editors of the
Agitatore. In November 1875 Zanardelli, Nabruzzi and
Joseph Favre founded the
Lake Lugano IWA section. Zanardelli began to move towards support of change through legal methods. Encouraged by
Benoît Malon, Zanardelli and Nabruzzi published their ''Almanacco del proletario per l'anno 1876'' in which they criticized the 1874 insurrection. During a news conference organized by his section in April 1876 Zanardelli spoke in favor of fighting for electoral reform. Later in 1876 Zanardelli moved to Paris and joined the circle of
Andrea Costa. In September 1877 he participated in the Universal Congress of Ghent, where he supported legal methods and opposed insurgency. He was a contributor to the journal
Égalité, which promoted the view that workers could and should use the vote to further their interests, rejecting the more extreme view that political parties were only tricking the workers by giving them the franchise. He was arrested in March 1878 along with Costa and others, and expelled from France. He moved to London, where he launched the journal
La Guerra sociale. Zanardelli organized some of the Italians in London into a circle of social studies, which he later expanded it into an international club of social studies. On 3 November 1879 he spoke at a protest meeting arranged by the German club against the arrest in Germany of the anarchists Just and Kaufmann.
Johann Most spoke at the same meeting. In 1879 he published a new paper, the
Bollettino socialista rivoluzionario (Revolutionary Socialist Bulletin). He then secretly returned to Paris where he joined the group led by
Amilcare Cipriani but did not talk. In December 1880 he participated in the Faiail Congress in
Chiasso, where he supported
Carlo Cafiero's anti-legal position. However, he began to be suspected as an agent provocateur. He returned to France, where he was again active in conferences. ==Later career==
