1878 Macedonian rebellion

The 1878 Macedonian rebellion (Greek: Μακεδονική επανάσταση του 1878) was a Greek rebellion launched in opposition to the Treaty of San Stefano, according to which the bulk of Macedonia would be annexed to Bulgaria, and in favour of the union of Macedonia with the Kingdom of Greece. This followed the brief Greco-Turkish war of 1878 in which Greece had declared war on 2 February against the Ottoman Empire, only for the Greek forces to return to their bases shortly after crossing the border due to the intervention of the Great Powers and the signature of the Treaty of San Stefano.

It is reported that revolutionary outbreaks in the same year, are located alongside Macedonia in Epirus, Thessaly and Crete, seeking union with the Greek state. In Macedonia there was greater willingness and enthusiasm than in Thessaly. The revolution had two main foci in Macedonia, one was on Olympus, and the other in Vourinos.
