Morlachs (Serbo-Croatian: Morlaci, Морлаци; Italian: Morlacchi; Romanian: Morlaci) is an exonym used for a rural Christian community in Herzegovina, Lika and the Dalmatian Hinterland. The term was initially used for a bilingual Vlach pastoralist community in the mountains of Croatia from the second half of the 14th until the early 16th century. Then, when the community straddled the Venetian–Ottoman border until the 17th century, it referred only to the Slavic-speaking people of the Dalmatian Hinterland, Orthodox and Catholic, on both the Venetian and Turkish side.
The exonym ceased to be used in an ethnic sense by the end of the 18th century, and came to be viewed as derogatory, but has been renewed as a social or cultural anthropological subject. As the nation-building of the 19th century proceeded, the Vlach/Morlach population residing with the Croats and Serbs of the Dalmatian Hinterland espoused either a Croat or Serb ethnic identity, but preserved some common sociocultural outlines.
