Polish-Lithuanian unions are a vast topic, undoubtedly still relevant today in some respects. The issues concerning the relationship between Poland and Lithuania, spread over several centuries and covering a large part of Central and Eastern Europe, are indeed — we could say — a “prehistory” of today’s European Union and the idea of a union of equal European nations. The article covers, in three separate parts, historiographic and research questions relating to the contemporary reception of the Polish-Lithuanian union concluded in Horodło and its contribution to the historic achievements of the Polish-Lithuanian state over the last few centuries. In the context of the opinions presented and the progress of studies into the Polish-Lithuanian relations in the past, as well as in the context of modern research into the Polish-Lithuanian relations between the 14th and the 19th centuries, particularly worthy of note is a meeting of Polish and foreign scholars studying these issues during an international conference entitled “The Union of Horodło against the background of Polish-Lithuanian relations from Kreva to the Mutual Pledge of the Two Nations” (Zamość, 27–28 September 2013). The conference, under the honorary patronage of the President of Poland, Bronisław Komorowski, was organised by the Society of the Descendants of the Great Sejm, City of Zamość, Museum of Zamość, Polish History Museum, Centre for East European Studies at the University of Warsaw, Institute of the Grand Duchy of Lithuania in Kaunas and Polish Heraldic Society.
