Italian occupation of Adalia

With the Treaty of London of 1915, Italy had negotiated, in exchange for the intervention alongside the Triple Entente, in addition to Trentino-Alto Adige up to the border at the Brenner Pass, to Venezia Giulia and some territories of Dalmatia, other compensations in the case of a dismemberment of the Ottoman Empire, such as the port of Antalya in Turkey and the contiguous territory, where a carboniferous basin was reported.

With the Mudros Armistice (the 30th of October, 1918), the Ottoman Empire accepted the conditions unilaterally dictated by the winning powers; while in Italy, where the idea of a Vittoria mutilata was growing, it was feared that the clause of the Pact of London would be annulled.

In these circumstances, the 9th of March 1919, the Italian government made an Italian expeditionary force in Anatolia disembark in Antalya, and in a brief time nearby localities were also occupied: Makri Budrun, Kuch-Adassi, Alanya, Konya, Ismidt and Eskişehir.

This show of force was met by a harsh opposition from the Greek government – not part of the Pact of London – who also aspired to occupy a large territory of Anatolia. In the absence of the Italian delegation headed by the prime minister Orlando, at the Paris peace conference, Greece managed to obtain, from the Supreme Council, permission to intervene on the Aegean coast of Anatolia. On 15 May 1919, therefore, the Greek Army made a landing at Smyrna with the occupation of Aydin, Magnesia, Kassaba, Ayalik and Edemieh.

A bitter dispute arose between the Italian and Greek governments, which was later resolved with a secret agreement signed on 29 July 1919 by Tittoni and Venizelos in which Italy renounced Adalia and the islands of Dodecanese except for Rhodes, in exchange for Greek support for an Italian “mandate” over Albania. This agreement, however, was denounced by the subsequent Italian Foreign Minister Carlo Sforza (June 1920).

The Paris Peace Conference, following the events of World War I, was articulated with a series of treaties with the individual defeated nations. The Ottoman Empire led to the Treaty of Sèvres (10 August 1920), which recognized Italy's area of influence on Antalya and its surroundings, as well as the possession of the Dodecanese, and the Greek occupation of Smyrna and its surroundings.

As the Greco-Turkish War spread, the Turkish revolutionaries obtained significant military assistance from Italy, which used the Antalya base to arm and train the troops of Mustafa Kemal Atatürk against the Greeks.[1]

Italy began the withdrawal of its expeditionary force in the autumn of 1922.[2]

After the victorious war against the Greeks and the establishment of Mustafa Kemal's Turkish Republic, the Treaty of Sèvres was annulled and replaced by the Treaty of Lausanne (1923). In this last act, Turkey confirmed to Italy the possession of the Dodecanese and recognized for the first time the Italian sovereignty over Libya, but did not grant it any area subject to economic influence or military occupation in Anatolia.[3]
