In the era of the Schengen Area (at least in the days before Covid-19), travel from Munich to Bozen/Bolzano or Ljubljana to Trst/Trieste is a decidedly unremarkable, albeit beautiful, adventure. Just as meaningful as the lack of border controls, travellers find all public signage in both Italian and German (and sometimes Ladin, too) upon arrival in Bozen/Bolzano. Signs in the streets of Trst/Trieste less reliably have Slovene alongside the Italian, but assistance with translation can be found with little difficulty. The Italian autonomous regions ‘with special statutes’ in which these cities reside – Trentino-Alto Adige (South Tyrol) and Friuli Venezia Giulia (the Julian March) – are multilingual territories that, at least on an official level, embrace a multiethnic heritage and reality. In fact, Trentino-Alto Adige's consociational democracy is widely regarded among political scientists as an international role model for how states can successfully protect and give voice to minority populations. Those unfamiliar with the more recent history of these regions might be surprised to learn of these avowedly multiethnic political and cultural structures. For much of the first half of the twentieth century, the regions’ two states – Austria-Hungary until 1919 and thereafter Italy – employed the ‘nationality principle’ to define policies and populations in these territories. As in most of Europe at the time, sovereignty was increasingly predicated on the contemporary ideal of the nation state, in which borders, ethnicity, language and citizenship were all bound together. Of course, as a multiethnic empire, Austria-Hungary was much more concerned about centralising state authority (and then fighting a world war) than national homogeneity, while Italy's nationalisation campaign in the interwar period became fundamental to its presence in the new provinces. Still, both states sought to classify and ultimately to control their border populations by privileging ethnolinguistic categories of citizenship.
