Abstract: The research into the relations between certain rulers, territories or peoples can be considered one of the classic topics of Medieval Studies. The Polish-Hungarian contact in the Middle Ages is no exception, several scientific and popular works have dealt with the relations of the Piasts and Árpáds, and their respective realms. Since we can only speak indirectly about the international relations of the High Middle Ages, the personal contacts of the rulers and the dynastic ties established between the ruling families are of great importance when studying the various elements of the relations. This paper focuses on an interesting and controversial episode of the matrimonial history of the Piasts of Poland and the Árpáds of Hungary. In my opinion, despite the poor state of the sources, it can be assumed that King Béla II of Hungary and Duke Bolesław III Wrymouth of Poland in 1135 – 1136, in order to put an end to their hostilities, concluded an agreement on a double marriage between their dynasties. Only one of the two planned marriages was realized, yet I believe that the hypothesis formulated in this study can be supported by a thorough analysis of the remaining sources and the political conditions of the 1130s.
