From 1887 he published various works in many newspapers and magazines such as Golub (The Pigeon), Neven, Bosanska Vila (Bosnian Fairy), Luča, Otadžbina (Fatherland) and Brankovo Kolo.

Upon the outbreak of war in 1914 Ćorović was arrested and sent to the notorious internment camp[3] of Boldogason in Hungary where he developed the disease that eventually caused his premature death.

In "Serbia's Great War, 1914–1918" by Andrej Mitrović on page 77, we read how he was mistreated as a prisoner-of-war: "Josip Smodlaka later recalled 'furious Hungarian soldiers wanted to massacre' him and his comrades in Budapest, and the prominent writer Svetozar Ćorović was forced by guards to run without food or water beside the railway transport carrying prisoners".

The severity of reprisal is itself the best testimony to the fear and anxiety inspired by the presence of active Serb soldiers from Bosnia and Herzegovina on the flanks and in rear of the invaders.

Works that particularly stand out include a novel Majčina Sultanija (1906) with an unusual figure of a provincial woman in the center of the story, Stojan Mutikaša[5] (1907) which tells the story of a man who transforms from the poor peasant boy into a great merchant and villain, and Jarani (Buddies, 1911), which portrays the Muslim population of Herzegovina in times of unrest ahead of the termination of the Turkish authorities.
