Kočić was one of the most important Bosnian Serb politicians of the Austro-Hungarian era, as well as one of Bosnia and Herzegovina's most important twentieth-century playwrights. He was noted for his fiery temperament and sharp wit, which he frequently deployed against the Austro-Hungarian authorities. Kočić's works not only influenced an entire generation of Bosnian intellectuals, such as the future Nobel laureate Ivo Andrić, but also the Serbian and Yugoslav nationalist movements, as well as the Bosnian autonomist and Yugoslav communist movements. Numerous streets in Bosnia-Herzegovina and Serbia carry his name and his likeness has appeared on Bosnian 100 KM banknotes since 1998.
