On the margins of the second treaty of Szőny data for the history of the signing of the treaty of Szőny in 1642

Growing interest can be observed in recent research focusing on the peace treaties between the Ottoman and the Habsburg Empires. In the present study, I provide some additional data and information on the history of the so-called second Treaty of Szőny (1642). After the review of contemporary political scene and the antecedents to the peace talks, I exclusively highlight one node of the communication network during the second Treaty of Szőny. I present this communication channel through the letters of the members of the famous Esterházy family (Dániel Esterházy and his elder brother, Miklós Esterházy). The correspondence of the Esterházys with other people points out the major problems of the earlier treaties between the Habsburgs and the Ottomans, for example the conscious falsification of the texts of the treaties. In addition, it is possible to learn other interesting details about the negotiations.
