Treaty of Rapallo, 1920

The Treaty of Rapallo was a treaty between the Kingdom of Italy and the Kingdom of Serbs, Croats and Slovenes (renamed Yugoslavia in 1929), signed to solve the dispute over some territories in the former Austrian Littoral in the upper Adriatic, and in Dalmatia.

The treaty was signed on 12 November 1920 in Rapallo, near Genoa, Italy. Tension between Italy and Yugoslavia arose at the end of World War I, when the Austro-Hungarian Empire dissolved and Italy claimed the territories assigned to it by the secret London Pact of 1915. According to the pact, signed in London on 26 April 1915 by the Kingdom of Italy and Triple Entente, in case of victory at the end of World War I, Italy was to obtain several territorial gains including former Austrian Littoral, Northern Dalmatia and notably Zadar (Zara), Šibenik (Sebenico), and most of the Dalmatian islands (except Krk and Rab).

These territories had an ethnically mixed population, with Slovenes and Croats composing over the half of the population of the region. The pact was therefore nullified with the Treaty of Versailles under pressure of President Woodrow Wilson, making void Italian claims on Northern Dalmatia. The objective of the Treaty of Rapallo was to find a compromise following the void created by the non-application of the London pact of 1915.
