Vlachs in the history of Croatia
In Serbian historiography all Dinaric/Shtokavian cultural attributes were without exception proclaimed as being Serb, and also often stressed the ethno-demographic discontinuity wanting to prove that the Croatian Military Frontier lost its original Croat population and received a new, ethnically Serb majority population, and also downplayed Croat and overemphasized the importance of the Serbs in the history of the Military Frontier. Serbian historiography strongly considered that the term Vlach indicated status and not ethnos, and that they didn't exist in later centuries as an ethnic group, yet were true Serbs. Sima Ćirković noted that the name was maintained due to different crafts, way of life and distinct form of social organization, until the differences lost their meaning, with Slavicization process lasting for centuries; he considered that Serbs absorbed many Vlachs and other ethnic groups. Many Serbian scholars, including foreign, claim that the settlers in the Military Frontier were Serbs or mainly Serbs.
