Grande Idée
Western Allies—particularly British Prime Minister David Lloyd George—had promised Greece territorial gains at the expense of the Ottoman Empire if Greece entered the war on the Allied side. These included parts of its ancestral homeland, Eastern Thrace, the islands of Imbros (Gökçeada), Tenedos (Bozcaada), and parts of Western Anatolia around the city of Smyrna (Izmir). Greece also wanted to incorporate Constantinople to achieve the Megali Idea, but Entente powers did not give permission.
