Born as
Giovanni Host-Ivessich in Fiume, then
Austria-Hungary, Nino Host obtained a license to middle school, and specialized as a dentistry technician. In the eve of World War I, he enrolled the
Sursum Corda. An Italian
irredentist, he defected to the Italians and participated as a volunteer, with the new
nom de guerre "Venturi" earning thrice a
Silver Medal of Military Valor and the rank of captain of the
Alpini and then the
Arditi. In November 1918 he arrived in Fiume with the Italian occupation troops, and immediately was co-opted in the
Italian National Council of Fiume. In Fiume in April 1919, Giovanni Venturi created the "Legion of Fiume", consisting of a core of volunteers officially to defend the city from the French army contingent in the city, who took a pro-
Yugoslav stance. In May 1919, Host-Venturi went to
Milan to meet
Benito Mussolini, from which he obtained promises of support, and immediately after, under the auspices of
Giovanni Giuriati he arranged several meetings in
Rome with
Gabriele D'Annunzio and was instrumental in organising his
Impresa di Fiume. Between June and July 1920, Host-Venturi also opened a series of secret meetings with Croat (specifically the
Croatian Committee),
Montenegrin and
Albanian separatists to explore the possibility of a concerted campaign that aimed to "prevent the consolidation of the so-called Yugoslavia". == Fascist leader ==
