ラパッロ条約
After Fiume was under Gabriele D'Annunzio's Italian Regency of Carnaro, the Treaty of Rapallo (1920) created the independent Free State of Fiume, which was immediately recognised by other states, including the United States, France and the United Kingdom. The state survived only one year "de facto" and four years "de jure". The joint administration of the port was never created.
