Serbian epic poetry (Serbian: Српске епске народне песме, romanized: Srpske epske narodne pesme) is a form of epic poetry created by Serbs originating in today's Serbia, Bosnia and Herzegovina, Croatia, Montenegro and North Macedonia. The main cycles were composed by unknown Serb authors between the 14th and 19th centuries. They are largely concerned with historical events and personages. The instrument accompanying the epic poetry is the gusle.
