The article is devoted to a linguistic analysis of discursive practices hostile to the Slovene community in Trieste that characterised the so-called “Hreščak case” (1965), a reshuffle of the Municipal Council that led to the designation of the first Slovene city councillor. The texts examined consist of minutes of the Trieste City Council. Methodologically, the study draws on the Discourse-Historical Approach within the framework of Critical Discourse Analysis. The first part of the article offers a sequential analysis of a text deemed particularly representative of the anti-Slavic discourse surrounding the “Hreščak case”: the speech in which Corrado Jona (Italian Liberal Party) announced his resignation as a city councillor. The second part presents the principal linguistic strategies underlying the anti-Slavic political discourse.
