The article discusses the political path of Franc Vidmar (1871–1935) from Trieste, who for the most part of his life engaged in the anarchist movement. At the turn of the century, after being convicted in his native Trieste, where he ideationally matured, he found himself on the list of twelve most wanted anarchists in Carniola (where he was registered as a resident for a while). After emigrating to the USA, he worked among Italian-speaking anarchists. He maintained contacts with like-minded people from other emigration groups and faced persecution several times.
