Born in
Cesena on 2 June 1873, Merloni studied in
Venice, graduating in languages in 1897. He joined the
Italian Socialist Party (PSI) at an early stage and became active as a journalist and organizer, contributing to leading socialist publications such as
Critica Sociale and
Avanti!. His knowledge of foreign languages and interest in
international socialism helped establish him as a prominent figure within the
reformist wing of the party. After early political activity in
Romagna, he moved to
Rome in 1900 to work on the editorial staff of
Avanti!, where he served as editor for several years. Within the PSI, he emerged as a key reformist leader aligned with
Filippo Turati, advocating gradual social and political reforms. He played a central role in campaigns for
universal suffrage and
proportional representation, emphasizing political education as essential to democratic participation. Elected to the
Chamber of Deputies in 1913, he represented the constituency of
Grosseto and remained active in socialist politics during
World War I, supporting neutralism and civil solidarity. Merloni was also involved in
Freemasonry, joining in 1906 and later publicly defending the compatibility of Masonic and socialist commitments. This position became increasingly controversial within the PSI, which formally declared the incompatibility of the two affiliations in 1914. Despite this, he maintained both roles for some time. Re-elected to parliament in 1919 and 1921, he denounced the rise of
Fascist violence. Under the Fascist regime, he remained under police surveillance, particularly for his Masonic connections. Arrested in 1936 after correspondence with exiled Freemasons was discovered, he was sentenced to internal exile. Shortly thereafter, following a cerebral hemorrhage, he was allowed to return to Rome, where he died on 30 October 1936. == References ==
