Vlachs in the history of Croatia
Some older sources like, Belsazar Hacquet (1739–1815) noted that although some call the Vlachs as Serbs, the Croats are their actual descendants. In the work "About the Vlachs" from 1806, Metropolitan Stevan Stratimirović stated that Roman Catholics from Croatia and Slavonia scornfully used the name Vlach for ""the Slovenians (Slavs) and Serbs, who are of our, Eastern confession (Orthodoxy)"", and that ""the Turks in Bosnia and Serbia also call every Bosnian or Serbian Christian a Vlach"". Scholars like Vuk Stefanović Karadžić, Ferdo Šišić, Vjekoslav Klaić, Petar Skok, vaguely argued according to the ideologies of the time, that the Vlachs lacked national consciousness, belonging to Serbs or Croats, that Orthodoxy made them Serbs, or that due to them being mainly Orthodox the Roman Catholic priests started to identify them with the Serbs/Rascians which eventually got adopted.
