On this day in 1924, Fascist Italy officially annexed Fiume: an early victory for Fascist imperialism

Fiume, for those of us unaware, was a disputed territory from 1918 to 1920, then a microstate under League of Nations and Italian supervision starting in November 1920.

On September 1919, Gabriele D’Annunzio and various other Italian ultranationalists (legionnaires) entered the territory and established a protofascist state, with the ultimate goal of making Fiume a territory of the Kingdom of Italy.

\ Per The Adriatic Sea Encyclopedia, representatives from the Kingdoms of Italy and Yugoslavia convened on January 27, 1924 and agreed to the Treaty of Rome — a.k.a. Italy-Yugoslavia Treaty — which partitioned(!) the microstate, assigning the City of Fiume to the Fascists and the City of Sušak to the Kingdom of Yugoslavia; the border between the countries passed along the river Rječina. The International League of Nations recognized the partition as legal on April 7, 1924.
