In addition to the Battle of Vienna, Poland had a history of defending Europe from the Ottomans throughout the 16th and 17th centuries. The Polish-Lithuanian Commonwealth, which Poland was part of at the time, often fought the Ottoman Empire to protect the Christian nations of Europe.
One famous battle in this context is the Battle of Khotyn (1621). In this battle, the Polish army, led by Hetman Jan Karol Chodkiewicz, successfully repelled the Ottoman forces from the region of modern-day Ukraine, which was a critical buffer zone for the rest of Europe.
During this period, Poland often acted as a key ally in the defense of Christendom. The Ottoman Empire posed a significant threat to Europe for centuries, and Poland, under kings like Sobieski, was one of the leading powers in resisting their advances.
Without Poland's military intervention, the course of European history might have been very different. The battle at Vienna especially is often cited as the moment when Europe was saved from Ottoman expansion.
