The Association of Serbo-Macedonians (Serbian: Друштво Србо-Македонци) was an interest group founded by intellectuals from the region of Macedonia in 1886, and based in Istanbul, Ottoman Empire. The association propagated a kind of pro-Serbian Slav Macedonian identity, distinguished especially from the ethnic identity of the Bulgarians.
Macedonian nationalism asserts a distinct Macedonian identity, and first emerged as a thin intellectual movement in the 1860s. However, until the early 20th century, Macedonian Slavs identified with the national church of their local priest as either "Bulgarian," "Serbian" or "Greek". The Bulgarian self-identitification was most prevalent then, and perceivable pro-Bulgarian sentiments endured up until the end of the Second World War. The Serbs and Bulgarians had already established their own nation-states and intellectuals from the region of Macedonia often sought their ideological support.
The Association of Serbo-Macedonians looked to Serbia for support in petitioning the Ottoman Empire in favor of its political aspirations. Its founders had all formerly been members of the Secret Macedonian Committee. This Committee was founded by Slav Macedonian expatriate students in 1885 in Sofia, Bulgaria, but it was quickly uncovered by the Bulgarian authorities and disbanded. Four of its members left Bulgaria, and went to Belgrade, Serbia. Meanwhile, the first "Gathering of Serbo-Macedonians and Old Serbs" was held in Belgrade on February 23, 1885. At that time the development of pro-Serbian Macedonian identity was directly encouraged by Belgrade as a stage to its final turning into Old Serbian (see Serbophilia and Serbomania).
In Belgrade, the group's members met with the Serbian politician Stojan Novaković who pledged his support. Novaković proposed to spread Serbophilia so as to counteract the strong Bulgarian influence in Macedonia. The decision to create the association in Istanbul was taken at a meeting of the Serbian government in early August 1886. At the same meeting was taken also a decision to create the Saint Sava society, both for dissemination of the Serbian propaganda in the region of Macedonia. Novakovic's diplomatic activity in Istanbul played a significant role for the realization of this ideas, especially through the establishment of the Association of Serbo-Macedonians. He was sent as the Serbian envoy in the capital of the Ottoman Empire, considered as one of the most important posts in that period. Shortly afterwards Novaković took up his appointment, where he met with two members of the Macedonian committee to initiate the plan: K. Grupchev and N. Evrov. Although this was only partially successful, Serbian schools were opened in the region of Macedonia, and books were printed in the Macedonian dialect with strong Serbian linguistic influence. Despite the fact, initially this schools attempted to develop a middle road between Serbian and Macedonian dialects, in 1889 when asked to the reprinting of these texts in the Macedonian dialect, Novaković recommended only the Serbian language should be used. He claimed, the anticipated attraction of the Macedonian dialect had not eventuated. In accordance with Novaković's plans the “Macedonism” was seen as a stage of the gradual Serbianisation of the Macedonian Slavs. As result, on the eve of the new century, he and his collaborators promoted already only pro-Serbian ideas.
