Since the beginning of the 19th century the Balkans has been a synonym for aggressive nationalism and unbridled violence; the two phenomena traditionally understood to be the key obstacles for its social development. This paper contests such views by arguing that it was the absence of protracted warfare and coherent nationalist doctrines that distinguishes the history of South Eastern Europe from the rest of the continent. Drawing critically on bellicose historical sociology and modernist theories of nationalism - with a spotlight on the work of Charles Tilly and Ernest Gellner. Drawing critically on bellicose historical sociology and modernists theories of nationalism the paper makes a case that it was not the abundance of nationalism and organised violence but rather their historical scarcity that proved decisive for the slow pace of social development in the Balkans.
