Sandanski's legacy remains disputed among Bulgarian and Macedonian historiography today. Macedonian historians refer to him in an attempt to demonstrate the existence of Macedonian nationalism or at least proto-nationalism within a part of the local revolutionary movement at his time.[6] Despite the allegedly "anti-Bulgarian" autonomism and federalism of Sandanski,[7] it is unlikely he had developed Macedonian national identity in a narrow sensе,[8] or he regarded the Bulgarian Exarchists in Ottoman Macedonia as a separate nation from Bulgarians.[9] Contrary to the assertions of Skopje, his "separatism" represented a supranational project, not national. More, the compatriots, who convinced Sandanski to accept such leftist ideas, were Bulgarian socialists, most of whom were non-Macedonian in origin. The designation Macedonian then was an umbrella term covering different nationalities in the area and when applied to the Slavic speakers in Ottoman Macedonia, it denoted mainly the then Bulgarian ethnic community there.[10] However, contrary to Bulgarian assertions, his ideas of a separate Macedonian political entity, have stimulated the subsequent development of Macedonian nationalism.
As initial member of the SMAC, which served directly the Bulgarian governmental interests,[11] and then of the left wing of the IMRO, which advocated the creation of a Balkan Federation, Yane Sandanski remains one of the most controversial[12]Bulgarian revolutionaries.[13] While the Bulgarian communist authorities mostly liked him for his leftist sympathies,[14] after the fall of communism he is described by some nationalist historians as a betrayer of the Bulgarian national interests in Macedonia.[15] Sandanski is portrayed by them as an Ottomanist, and collaborationist of the Young Turks, seen as Bulgarian enemies, and as the man who started the fratricidal war into the IMRO. He has been accused also of being transformed himself from a revolutionary into a businessperson whose political motivation became only the money earning. On the contrary, in North Macedonia, the positive connotation of him, created in the times of Communist Yugoslavia is still alive. Since then the Macedonian historiography has emphasized the particularity of the IMRO's left wing,[16] while in fact Yugoslav communism and Macedonian nationalism are closely related.[17] Thus, he is portrayed by the Macedonian historians as a freedom fighter against the “Greater Bulgarian chauvinism” and the “Turkish yoke”.

^The way Bulgarian and Macedonian history and identities are intertwined is exemplified by the dispute over the identity of revolutionary heroes such as Gotse Delchev and Yane Sandanski. Bulgarian nationalists, for example, ridicule their Macedonian counterparts' identification with Sandanski, since archival documents refer to him as Bulgarian.

^The other prominent member of the Socialist Workers' Federation, besides the Sephardic Circle and the “anarcho-liberals,” was the People’s Federative Party–Bulgarian Section. The latter was founded in April 1909 by IMRO members who actively participated in the Young Turk Revolution and the “Army of Freedom” march on Istanbul to quell the countercoup in 1909. It was strongly divided along ideological lines and different strategic choices around social democrats like Dimitîr Vlahov (1878–1953), nationalists with socialist leanings like Iane Sandanski (1872–1915), and nationalists like Khristo Chernopeev.

^In his youth Sandanski was a member of the Bulgarian nationalist Supreme Macedonian Committee, which main idea was the direct unification of Macedonia with Bulgaria, but later switched to the IMRO. However, the first name of the IMRO was "Bulgarian Macedonian-Adrianople Revolutionary Committees", which was later changed several times. Initially its membership was restricted only for Bulgarians. It was active not only in Macedonia but also in Thrace (the Vilayet of Adrianople). Since its early name emphasised the Bulgarian nature of the organisation by linking the inhabitants of Thrace and Macedonia to Bulgaria, these facts are still difficult to be explained from the Macedonian historiography. They suggest that IMRO revolutionaries in the Ottoman period did not differentiate between ‘Macedonians’ and ‘Bulgarians’. Moreover, as their own writings attest, they often saw themselves and their compatriots as ‘Bulgarians’ and wrote in Bulgarian standard language.

^The Internal organization's leaders rejected the national-separatist idea of promoting the Macedonian into a distinct language. They opposed Misirkov's program and his book seems to have been burned in Sofia by TMORO activists. When, in 1905, Čupovski tried to organize a "Pan-Macedonian conference" in Veles, he was expelled from the town by a local chief of the Internal organization. At the same time, the Macedonian nationalists did not recognize their program even in the allegedly "anti-Bulgarian" autonomism of Sandanski and, in 1914, accused him of "non-Macedonian" activity.

^It is nevertheless doubtful that Sandanski and the other leftists of this period developed Macedonian nationalism stricto sensu. During the constitutional regime established by the Young Turks, Sandanski and his followers set up a “People's Federative Party” that was supposed to include a number of ethnic sections, each one representing a distinct "nationality" of Macedonia... This federalist project, however, failed and the only section that was set up within the "People's Federative Party" was the one of Sandanski himself and of his "co-nationals," which was actually called the "Bulgarian section."

^In Macedonian historiography, Sandanski has been portrayed as a fighter for Macedonian independence against the Young Turks and the Turkish rule in Macedonia. I think that this interpretation is highly problematic. He certainly stood for the autonomy of Macedonia, but this does not mean that he regarded the Slavic Christians in Macedonia as a separate nation—namely, a “Macedonian nation.” For more see: Mehmet Hacısalihoğlu, «Yane Sandanski as a political leader in Macedonia in the era of the Young Turks», Cahiers balkaniques [En ligne], 40 | 2012, mis en ligne le 21 mai 2012, doi:10.4000/ceb.1192.
