Overview
The Treaty of Rome was agreed on 27 January 1924, when Italy and the Kingdom of Serbs, Croats and Slovenes agreed that Fiume would be annexed to Italy as the Province of Fiume, and the town of Sušak would be part of the Kingdom of Serbs, Croats and Slovenes.
Fiume and Sušak would have a joint administration of the port facilities. Both towns are now in the city of Rijeka, Croatia.
Background
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.
