Congress of Gniezno

The Congress of Gniezno, held in 1000 AD, was a significant diplomatic meeting between European leaders, notably Polish Duke Bolesław I and Holy Roman Emperor Otto III. It aimed to strengthen ties and establish Poland as a recognized power in Europe. The event marked the elevation of the Polish Church's status, leading to the establishment of an archdiocese in Gniezno. This congress not only solidified Bolesław's rule but also integrated Poland into the broader European political and religious landscape, highlighting the importance of alliances and religious authority in medieval politics.
