Immediately after the establishment of the power of the Arpadović dynasty in the newly created Hungarian-Croatian Kingdom, the revitalization of the population began for Slavonia. Until then, Slavonia, which had been largely depopulated by people, began to be settled by noble families who obtained ownership of arable land in it. Owned land was the most important way of distinguishing the nobles who slowly immigrated to the western part of medieval Slavonia. Although they formally belonged to the same class, the nobles differed from each other in terms of wealth, power and influence. Numerous noble families that were part of the Slavonian Middle Ages show us how dynamic life was at that time. Family friendships and alliances are a key part of the life of a Slavonian noble person who had to choose them wisely in order to stay as long as possible on the social and political scene of the kingdom. Quality and daily communication with the king and other members of society contributed to the influence of an individual who, thanks to this, was able to achieve very important political functions. In addition to their political functions, the nobles portrayed their reputation through marriage ties, which confirmed their place in society. Choosing a suitable marriage partner could have a long-term positive effect on the fate of the noble family, which is why choosing a spouse was one of the most important tasks in the life of a noble. In the case of the nobles with whom this paper deals, we come across examples of capable individuals who exalt their family name. We find examples of the importance of family ties, alliances and enmity. The period of the late Middle Ages in Western Slavonia brought numerous powerful family names that held the most important positions in the kingdom.
