During the First Balkan War, fighting against the Ottomans, Greece had occupied most of Epirus, southern Macedonia with the great port city of Thessaloniki and most of the islands of the Aegean Sea (except the Italian-occupied Dodecanese). In the second war, it expanded its territory in Macedonia further at the expense of Bulgaria. Since Western Thrace remained under Bulgarian control (it would be ceded to Greece in the 1919 Treaty of Neuilly), Greece shared no land border with Ottoman Empire.
