Polscy negocjatorzy i gwaranci traktatu lubowelskiego z 15 marca 1412 r.

The Polish and Hungarian monarchs and their spouses, courts, as well as numerous advisers met on March 15, 1412 in Lubowla in Spiš, where a peace treaty was concluded. The article presents the circumstances of initiating Polish–Hungarian talks in the autumn of 1410 (the mission of Zawisza Czarny) and the process of Poland and Hungary becoming closer in the years 1411–1412, culminating in a congress in Lubowla. Negotiations took place in three rounds and lasted a total of several months. They were characterized by a consistent desire to achieve peace. A significant role was played in particular by the king’s four advisers: the Archbishop of Halice and then Gniezno Mikołaj Trąba, the Bishop of Poznań Wojciech Jastrzębiec, the voivode of Kraków Jan from Tarnów, and the Marshal of the Kingdom Zbigniew from Brzezie. The following part presents the poorly-known Polish list of guarantors of the Treaty of Lubowla, consisting of 50 people. Individual guarantors have been identified and described in a prosopographic manner. Attention was drawn to other examples of their guarantee of peace treaties. By analyzing the group of guarantors the author concludes that the main peace documents were written down and sealed during the meeting in the Spiš region. The guarantors of peace were also chosen there from among the dignitaries and knights of the court accompanying the monarchs. The list of guarantors of the Polish document was dominated by residents of Lesser Poland. A relatively large group of guarantors consisted of untitled knights of the court, mainly famous knights, participants of the war with the Teutonic Order in the years 1409–1411. The author recommends publishing both treaty documents as well as the set seals.
