Border-Crossings and Migration in the Croatian and Slavonian Military Frontiers in the Early Modern Period

Significant geographical discoveries and the emergence of modern cartography, when combined with the concept of a territorial state, brought meaningful changes how borders were conceived during the early modern period. A diffuse image that had prevailed from antiquity to the late Middle Ages was replaced by a clear idea of a fixed border (Baramova, 2010). The role of the Military Frontier as a wider borderland was two-fold: It served as a buffer zone against the Ottoman Empire for the Habsburg hereditary lands and the still unconquered Croatian territories, and it was also an area of intense migration, especially for the Vlach population from the southeastern Dinaric region. After the suppression of the Ottomans and the first international demarcation of the Croatian territories in 1699/1700, migration to the Military Frontier increased, both from the central European area and from the southern and southwestern parts of the Balkan Peninsula. This paper discusses the role and perception of this borderland and especially of Croatia’s Military Frontier. Through interpretation and explanation of several typical examples of border crossings in this area, both before and after the first official demarcation in 1699, the paper will attempt to answer the question of how the migration processes influence the development and strengthening of the early modern state and its institutions
