The Internal Macedonian-Adrianople Revolutionary Organization, backed by the Supreme Macedonian-Adrianople Committee and Bulgarian military personnel, sought autonomy for the Macedonia and Adrianople regions under Ottoman rule. Mounting repression and the absence of reform prompted the organization to plan an armed uprising, though key leaders including Gotse Delchev had already been killed or arrested before it began.
Beginning on August 2, 1903, rebels seized control of parts of the Manastir vilayet and briefly established the Kruševo Republic, while a separate revolt in the Adrianople vilayet created the Strandzha Republic on August 19. Both provisional governments were quickly crushed by Ottoman forces, yet rebels sustained a guerrilla campaign for nearly three months across multiple vilayets before the uprising was fully suppressed.
Suppression of the uprising triggered a mass refugee exodus from Macedonia and Thrace, primarily to Bulgaria but also to North America. European powers pressured the Ottoman sultan to adopt the Mürzsteg Reforms, and Bulgaria signed a bilateral agreement in 1904 pledging not to support the revolutionary movement. Neither the reforms nor the agreement was fully implemented, leaving the underlying tensions unresolved.
