majority of the population from Bosnia and Herzegovina in general"(This also applies to the entire Western Balkans as a mixture of Slavic and indigenous population), but also states that "there are none direct sources to support Vlach colonization of these lands." Serbian Orthodox Church have a decisive role in the process of national identification of Vlachs in Croatia and Bosnia and Herzegovina who became Serbs while Catholic Vlachs became Croats. Today only a small part of former Vlachs declares with this name. According to Bogumil Hrabak, Vlachs katuns which exist in Herzegovina with old Balkan, ethnically probably Arbanas basis does not mean that ancient Slavs of Herzegovina were all Arbanas. Considering it was a transit area and before 1330, Vlachs arrived from several directions, most Herzegovinian katuns came from Serbia and Albania that is, from Thessaly and Epirus, the main Vlach areas in the Balkans. According to Noel Malcolm, today it makes no sense to claim that Bosnian Serbs are "actually" Vlachs because members of the Serbian Orthodox Church over time crossed the Drina and moved to Bosnia or moved north from Herzegovina, but not all people who settled northern Bosnia in the 15th and 16th century were Vlachs. There were too many arrivals and departures to determine what is the percentage of Vlach ancestors of Bosnian Serbs since the Vlachs did not only contribute to the growth of the Serbian population, Vlachs mostly in Croatia converted to the Catholic faith, and many of them in Bosnia converted to Islam. Notable Bosnian Vlachs Hasan Pasha Predojević (c. 1530 – 22 June 1593) – the Predojević Vlachs are first mentioned 1372, while since 1468 were included in the Ottoman hierarchy.
