The Serbian secret organization in eastern Bosnia (Serbian: Српска тајна организација у источној Босни/Srpska tajna organizacija u istočnoj Bosni) was a Serb secret revolutionary organization active in 1849–55 in the eastern Bosnia Eyalet–the kaza of Srebrenica, Višegrad, Rogatica and Nova Varoš. It was part of a larger network of organizations active in Ottoman Europe (Rumelia), envisaged by Serbian politician Ilija Garašanin. The aim of the organization was to prepare an uprising against Ottoman rule. Pavle Marinović was responsible for eastern Bosnia, and was subordinated to Toma Kovačević, Garašanin's man responsible for Bosnia as a whole. Marinović established the organization network in the four kazas in eastern Bosnia in the second half of 1849 and in 1850, and appointed chiefs of each kaza that reported on numbers of Orthodox and Muslim men, the relief, strategical objects and Ottoman military forces. It was concluded that half of the Serb population there were well-armed and ready to revolt. However, as Serbia did not pursue a war of liberation against the Ottomans, in 1851 the organization turned into an intelligence agency. The organization's failure was largely due to lack of funds.
