The
Supreme Macedonian-Adrianople Committee (SMAC) led by General
Ivan Tsonchev and
Stoyan Mihaylovski started to prepare the uprising in 1901. The goal of the uprising was to cause the Great Powers to intervene, which would force the
Sublime Porte to implement Article 23 and Article 62 of the
Treaty of Berlin, granting
autonomy to Macedonia and Adrianople. In 1901, SMAC began sending detachments to Ottoman Macedonia to prepare the population for an uprising.
Ivan Garvanov, who was the leader of the
Internal Macedonian Revolutionary Organization (IMRO), cooperated with SMAC. SMAC was able to increase its influence in Ottoman Macedonia. Starting from 1902, detachments from Bulgaria entered the
Serres sanjak. Many local committees in Macedonia strongly resisted SMAC's advances. Garvanov became convinced that an uprising in 1902 would have fatal consequences for the Macedonian revolutionary movement. Tsonchev's faction was opposed by factions by
Gotse Delchev and
Boris Sarafov. The Central Committee of IMRO in Salonica disapproved of Tsonchev's plans for an uprising and made preparations in northeast Macedonia to resist against Tsonchev's followers. In August 1902, Bulgarian military officer
Anastas Yankov went to western Macedonia to prepare the planned uprising. Yankov's attempts to raise an uprising ended in failure, due to the opposition of IMRO's local leaders. At the end of August and the beginning of September 1902, SMAC concentrated the detachments of officers
Petar Darvingov, Todor Saev, Sofroni Stoyanov, Yordan Stoyanov, Hristo Sarakinov, Dimitar Dumbalakov, Anton Bozukov, Vladimir Kanazirev and Konstantin Kondov in Pirin, under the command of Ivan Tsonchev and Stefan Nikolov. ==Uprising==
