The Treaty of Rome of January 27, 1924 was an agreement by which Italy and the Kingdom of Serbs, Croats and Slovenes revoked the parts of the Treaty of Rapallo from 1920, which had created the independent Free State of Fiume. The agreement was that Fiume, now Rijeka in Croatia, would be annexed to Italy as the Province of Fiume, while the town of Sušak was assigned to the Kingdom of Serbs, Croats and Slovenes. According to the treaty Fiume and Sušak would share a joint administration of the port facilities.
Ratifications of the agreement were exchanged in Rome on February 22, 1924, and it became effective on the same day. It was registered in League of Nations Treaty Series on April 7, 1924.[1]
