During the early 14th century, tensions were rising in Central Europe, particularly between the kingdoms of Bohemia and Poland. King John of Bohemia was embroiled in territorial disputes with Casimir III, the King of Poland, as each sought to assert dominance over regions that were crucial for trade and strategic advantages. In an effort to alleviate these conflicts, Charles I of Hungary convened a congress in Visegrád, hoping to bring the two monarchs together. This gathering was significant not just for its immediate potential to resolve disputes but also as a demonstration of Charles's ambition and his role as a peacemaker in the region. The negotiations were intense; however, the atmosphere fostered by Charles allowed for a candid exchange of grievances and suggestions for compromise.

At the congress, both sovereigns were reminded of their shared interests and the potential benefits of a cooperative approach. Through various discussions, including proposals regarding borders and trade agreements, a reconciliation began to form. John of Bohemia and Casimir III made commitments to pursue amicable relations, which were crucial for ensuring stability in the region. This congress was thus more than a simple meeting; it laid the groundwork for improved diplomatic ties and demonstrated the power of negotiation over military conflict. Charles I's ability to host and facilitate such an important diplomatic event showcased Hungary's rising political influence during this period.
