Among notable supporters of Yugoslavism and a Yugoslav identity active at the beginning of the 20th century were famous sculptor Ivan Meštrović (1883–1962), who called Serbian folk hero Prince Marko "our Yugoslav people with its gigantic and noble heart" and wrote poetry speaking of a "Yugoslav race"; Jovan Cvijić, in his article "The Bases of Yugoslav Civilization", developed the idea of a unified Yugoslav culture and stated that "New qualities that until now have been expressed but weakly will appear. An amalgamation of the most fertile qualities of our three tribes Croats, Slovenes will come forth every more strongly, and thus will be constructed the type of single Yugoslav civilization-the final and most important goal of our country."
