摘要：The work is focused on a specific geographical region and research questions concerning Susedgrad feudal possession and the demographic change caused by Ottoman attacks on eastern borders of Croatian medieval kingdom. These attacks, recorded in medieval and early modern written historical sources in 15th and 16th century, caused the greatest demographic change in Croatian history. In fact, its consequences were so great that we often hear, in the humanities scientific field, about the before- and after- migratory period. For the Susedgrad medieval and early modern manor the migrations meant great economical advancement, because a well inhabitated feudal possession meant more workers, crop and money for the landlord. The second, much more far reaching consequence, concerns the dialect used by the immigrants. These immigrants spoke the ikavian-čakavian dialect. During time, they assumed kaykavian elements, but kept the ikavian reflex of jat. This paper analyses earliest recorded place names, which are the only evidence of linguistic and dialectical development in 15th and 16th centuries. Using the research of Croatian linguists, historical written sources together with onomastic and historical methodology, this paper tries to give the answers concerning spatial and temporal boundaries of pre- and post-migration situation in the Susedgrad feudal possession. The author is especially interested in the western part of the estate, the so-called Brdovečko prigorje, the home of kaykavianikavian speakers. The author has analised and transcribed the written sources, obtaining a data-base of several thousand personal names, surrnames and place names. These written sources are landlord and church documents with lists of srefs and their obligations. These obligations were: tithe in wine and grain, taxes, and the tlaka or tenant-peasants’ corvée labour.
