The first recognized work of anthropological interest in ethnicity was done by Erdeljanović, named as one of the founding fathers of Serbian ethnology. His works are influenced by ideas of evolutionism and Yugoslavism and he represented the theory that Yugoslavs are people of one blood and one origin.[2][3]
