Yane Ivanov Sandanski or Jane Ivanov Sandanski (Bulgarian: ??? ?????????, Macedonian: ???? ?????????) (18 May 1872 – 22 April 1915), was a Bulgarian revolutionary recognised as a national hero in Bulgaria and North Macedonia.
In his youth Sandanski was interested in Bulgarian politics and had a career as governor of the local prison in Dupnitsa.
Then he was involved in the anti-Ottoman struggle, joining initially the Supreme Macedonian-Adrianople Committee (SMAC), but later switched to the Internal Macedonian-Adrianople Revolutionary Organisation (IMARO).
Sandanski became one of the leaders of the IMARO in the Serres revolutionary district and head of the extreme leftist wing of the organisation.
He supported the idea of a Balkan Federation, and Macedonia as an autonomous state within its framework, as an ultimate solution of the national problems in the area.
During the Second Constitutional Era he became an Ottoman politician and entrepreneur, collaborating with the Young Turks and founded the Bulgarian People's Federative Party.
Sandanski took up arms on the side of Bulgaria during the Balkan Wars (1912–13).
Finally he was involved in Bulgarian public life again, but was eventually killed by the rivalling IMARO right-wing faction activists.
Sandanski's legacy remains disputed among Bulgarian and Macedonian historiography today.
Macedonian historians refers 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.
Despite the allegedly "anti-Bulgarian" autonomism and federalism of Sandanski, it is unlikely he had developed Macedonian national identity in a narrow sens?, or he regarded the Bulgarian Exarchists in Ottoman Macedonia as a separate nation from Bulgarians.
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 local Slavs, it denoted mainly the regional Bulgarian community.
However, contrary to Bulgarian assertions, his ideas of a separate Macedonian political entity, have stimulated the subsequent development of Macedonian nationalism.
