Treaty of Rapallo
On 12 September 1919, D'Annunzio occupied the city of Rijeka (Fiume) and proclaimed the Italian Regency of Carnaro, but the approval of the Treaty of Rapallo on 12 November 1920 turned the territory into an independent state, the Free State of Fiume. Other parts of the Treaty of Rapallo were supposed to solve the dispute between the Kingdom of Italy and the Kingdom of Serbs, Croats and Slovenes (renamed Yugoslavia in 1929). It included Italian annexation of parts of Carniola, several Adriatic islands, and the city of Zadar (Zara).
