Jančić's Revolt

First Mašići Revolt or Jančić's Revolt (Прва Машићка буна/Јанчићева буна) was a revolt led by ethnic Serbs in the Gradiška-region against the Ottoman government in the Bosnia Eyalet. It broke out in September 1809 following econominal, national and religious deprivation of rights of Serbs.

With the First Serbian Uprising that broke out in the Sanjak of Smederevo in 1804, hajduk actions also began to the west of the Drina, especially after the decisive Serbian victory at the Battle of Mišar (1806). Hajduks (brigands) also arrived from Serbia, and they were especially active on the Kozara. Jovan Jančić Sarajlija was the organizer of the uprising with help from the Metropolitan Benedikt Kraljević. The Ottomans sensed that something was in planning, so they increased the terror against the population, and Kraljević fled to Austria. While planning the operation, Jančić turned to Austria and France for help, but without any success. In the dilemma of whether to start an uprising without proper planning, was forestalled by a progress of events.

Peasants took arms on 23 September 1809, in the region of Gradiška, beginning from Mašići. The fighting began on 25 September, and on the night of 25/26 September, the Ottomans, who had gathered a strong army, captured Jančić in his house. The rest of the rebels, without any commander, were afraid and retreated to their villages. Only the rebels in Kozara and Motajica continued, and offered strong resistance, which the Ottoman finally crushed by mid-October, after burning villages and looting. The Roman Catholic population (local Croats, etc.) of the Bosnian frontier intended to join the uprising, but never did. After the crushing of the revolt, the Ottoman government in the region captured the rebel leaders and executed them.

Another revolt broke out in 1834, following the Priest Jovica's Revolt, in Mašići.
