ENThe article refers to the diplomatic talks and discussions in the years 1492–1506 whose aim was to renegotiate the conditions of the Polish-Lithuanian union. The author is of the opinion that in spite of the evolution of the Polish-Lithuanian relations, during the reign of Casimir Jagiellon, the Union of Horodło was still regarded as formally binding. The course of the political negotiations has been presented taking into account the interests of all interested parties – the Kingdom of Poland, Grand Duchy of Lithuania and the Jagiellon dynasty. Hence the author’s minute analysis of the successive changes within the detailed conditions of the planned union. Apart from that, the author discusses the issue of the preparation of the union documents and their circulation. The author is of the opinion that the apparent renewal of the Union of Horodło in 1501, reported by some sources, was in reality associated with the transumptions of the Horodło and Grodzieńsk agreements, which were dated only a few months after the formulation of the act of the new Polish-Lithuanian union. Yet the purpose of transuming the documents of the old unions, does not seem to be quite clear. [From the publication]
