This website presents the results of the research project 'Polonica Philosophica Orientalia: Philosophy in the Polish-Lithuanian Commonwealth from the 16th to 18th Centuries and the Historiography of Philosophy in Poland, Lithuania, Belarus and Ukraine”, which was funded by the Republic of Poland's National Programme for the Development of Humanities and realised between 2018 and 2025.

The project aimed to make sources accessible by describing, transcribing, translating and commenting on them, as well as providing a common interpretation of the history of philosophy in this part of Europe. As part of the project, we have prepared a series of editions of manuscript sources, a lexicon and two monographs on intellectual geography and political theory.

Coordinated at Jagiellonian University in Cracow, the project brought together scientists from the following institutions:

• H. Skovoroda Institute of Philosophy, National Academy of Sciences of Ukraine, Kyiv

• Lithuanian Culture Research Institute, Vilnius;

• Vernadsky National Library of Ukraine, Kyiv

• Library of the University of Vilnius

• Wroblewski Library, Lithuanian Academy of Sciences, Vilnius

• Institute of Philosophy, Academy of Sciences of Belarus, Minsk (until 2022)

Starting from Jagiellonian times, intellectual life in the region was closely linked to the Polish and Lithuanian states and their confederations, as well as the Ukrainian and Belarusian states and other forms of collective identity. Thus, the project focused on the relationship between philosophy and politics. The research covers a variety of regions and their institutional landscapes, as well as the different nation-building processes. We consider the following questions and similar ones:

• How did philosophers react to political problems, and how did they try to influence political life?

• To what extent did they uphold the Jagiellonian legacy in Poland, Lithuania, Belarus and Ukraine?

• What arguments did philosophers use to criticise the Jagiellonian heritage?

• Which elements of the Jagiellonian political culture made their way into the political and cultural narratives of our countries?
