 Nevertheless, in 1914 the Carnegie Council for Ethics in International Affairs report states that the Serbs and Greeks classified the Slavs of Macedonia as a distinct ethnic group "Macedonians Slavs" for political purposes and to conceal the existence of Bulgarians in the area.However, after the Balkan Wars (1912–1913) Ottoman Macedonia was mostly divided between Greece and Serbia, which began a process of Hellenization and Serbianisation of the Slavic population and led in general to a cease in the use of this term in both countries.On the other hand, Serbian and Bulgarian left-wing intellectuals envisioned in the early 20th century some sort of "Balkan confederation" including Macedonia, should the Austro-Hungarian Empire and Ottoman Empire dissolve.
