Treaty of Rapallo

Date: November 12, 1920 • Location: Belgrade, Serbia

The Kingdom of Italy and the Kingdom of Serbs, Croats and Slovenes signed the Treaty of Rapallo to establish national borders east of the Adriatic Sea.

The Kingdom of Italy was a unitary state that existed from 17 March 1861, when Victor Emmanuel II, King of Sardinia, was proclaimed King of Italy, until 18 June 1946, when the monarchy was abolished, following civil discontent that led to an institutional referendum on 2 June, resulting in the establishment of the modern Italian Republic. The kingdom was established through the unification of several states over a decades-long process, called the Risorgimento. That process was influenced by House of Savoy-ruled Sardinia, which was one of Italy's legal predecessor states.
