Morlachs has been 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 in the 17th century, it referred only to Slavic-speaking, mainly Eastern Orthodox but also Roman Catholic people. The Vlach, i.e., Morlach, population of Herzegovina and Dalmatian hinterland from the Venetian and Turkish side were of either Roman Catholic or Christian Orthodox faith. Venetian sources from 17th and 18th centuries make no distinction between Orthodox and Catholics, they refer to both groupings as Morlachs. 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 Serb or Croat ethnic identity, but preserved some common sociocultural outlines.

Vlachs in the history of Croatia
The term Vlachs was initially used in medieval Croatian and Venetian history for a Romance-speaking pastoralist community, called "Vlachs" and "Morlachs", inhabiting the mountains and lands of the Croatian Kingdom and the Republic of Venice from the early 14th century. By the end of the 15th century they were highly assimilated with the Slavs and lost their language or were at least bilingual, while some communities managed to preserve and continue to speak their language (Istro-Romanians).
