 The Young Turks revolution, the Asia Minor Expedition and subsequent Catastrophe, had as a result, apart from the 1.5 million refugees, the death of approximately 1 million ethnic Greek civilians (the most notable case being the Greek genocide) and the hostage of hundreds of thousands of Greek men, who were not allowed to leave Anatolia, but were sent to "labor battalions" after the war (it is estimated that as many as 150,000 Greek men from Smyrna were not allowed to go to Greece).The demographic bleeding of the refugee population continued in Greece, where thousands of people (especially women and children) died of diseases.The diseases had also an impact on the native population of the country.
