Venizelos–Tittoni agreement

The Venizelos–Tittoni agreement was a secret non-binding agreement between the Prime Minister of Greece, Eleftherios Venizelos, and the Italian Minister of Foreign Affairs, Tommaso Tittoni, in July 1919, during the Paris Peace Conference.

The agreement was an effort to achieve an agreement about the conflicting territorial claims of the two countries.

In January 1920, Venizelos made known the agreement to the Supreme Allied Council with no negative reaction. The stance of Italy changed in July 1920, when the new Italian Minister of Foreign Affairs, Carlo Sforza, with a secret note to the Greek government renounced the agreement. Formally, the agreement was renounced by Italy on August 1922.
