At the end of World War I, the Treaty of Sèvres made most of the Province of Aleppo part of the newly established nation of Syria, while Cilicia was promised by France to become an Armenian state. However, Kemal Atatürk annexed most of the Province of Aleppo as well as Cilicia to Turkey in his War of Independence. The Arab residents in the province (as well as the Kurds) supported the Turks in this war against the French, including the leader of the Hananu Revolt, Ibrahim Hananu, who directly coordinated with Atatürk and received weaponry from him. The outcome, however, was disastrous for Aleppo, because as per the Treaty of Lausanne, most of the Province of Aleppo was made part of Turkey with the exception of Aleppo and Alexandretta; thus, Aleppo was cut from its northern satellites and from the Anatolian cities beyond on which Aleppo depended heavily in commerce. Moreover, the Sykes-Picot division of the Near East separated Aleppo from most of Mesopotamia, which also harmed the economy of Aleppo. The situation was exacerbated further in 1939 when Alexandretta was annexed to Turkey, thus depriving Aleppo of its main port of Iskenderun and leaving it in total isolation within Syria.
