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.
