[1] UAIS/SIAU was founded in the summer of 1945 by the Regional National Liberation Committee, as an umbrella organization of different groups seeking autonomy for Trieste or its integration into Yugoslavia.

At the founding congress Triestine, Italian, American, Yugoslav, Soviet and Fiuman flags were displayed, as well as portraits of Clement Attlee, Joseph Stalin, Harry Truman, Giuseppe Garibaldi and Josip Broz Tito.

[4] UAIS/SIAU used a version of the Italian flag with a red star (a practice common in Italy as well in this period).

Furthermore, the Allied Military Government restricted the UAIS/SIAU May Day rally the Slovenian-dominated working class areas, whilst letting pro-Italian groups demonstrate in the city centre.
