Jančić's Rebellion

Jančić's Rebellion (Јанчићева буна/Jančićeva buna), also known as the First Mašići Rebellion (Прва Машићка буна/Prva Mašićka buna), was a rebellion led by ethnic Serbs in the Gradiška region against the Ottoman government in the Bosnia Eyalet. It broke out in September 1809 following a string of econominal, national and religious deprivations of the rights of Serbs.

Background
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.

The work of priest Jovo from Svinjar, priest Nikodim from Mačkovac, and the brotherhood of the Moštanica Monastery also led to the uprising.

Location
The revolt broke out in the Bosnian Frontier and Bosnian Posavina.

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 actions 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 on the mountains of 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.

Aftermath and legacy
Another revolt broke out in the region in 1834, following Priest Jovica's Rebellion, in Mašići, known as the (Second) Mašići Rebellion.

A memorial plaque stands in Mašići dedicated to the fallen people of both rebellions.
