Greek–Serbian Alliance of 1867
In the middle of the 19th century, most of the territory of Balkans was still part of the Ottoman Empire, with several newly established independent or autonomous entities like Serbia and Greece. All of them struggled to expand their influence and territory at Ottoman expense. Their intention was strongly opposed by Austria who opposed development of Balkan nations and revolutions in the Ottoman provinces of Europe ("Rumelia"). Napoleon III was the champion of the idea of Balkan nationalism and fostered Serbia and Greece to build alliances and undermine Ottoman influence in the region. France planned to resolve the Balkan Eastern Question through gathering of all Balkan Slavic people, including Bulgarians, around Serbia as their pillar. This was not only informally suggested by French diplomats since 1861, but also formally proposed in Saint Petersburg in 1867. The establishment of Balkan alliances was supported and aided by Russia because it corresponded with its policy of promoting Balkan unity.
