Vlachs in the history of Croatia
While the Slavic communities managed to form national identities founding regional provinces and kingdoms, Romance-speaking Vlachs didn't manage to form a national identity and were prone to assimilation. However, even if they were prone to national, linguistical and cultural assimilation with the Slavs, they did contribute to their respective communities. The problems the Vlachs faced with the creation of the national identity did not differ very much from what other rural communities face. Rural people comprised the majority of the population in the Middle Ages, and the centuries of war, conquest, regional boundaries, migrations, religious conversions, cultural blending and socio-economic problems affected the belonging of a population to a specific South Slavic national group. The regions of Lika (which mostly involved the Croatian Military Frontier) and Dalmatia were the border area between Habsburg, Ottoman and Venetian empires, a place of mass migrations and mixing of communities.
