At the Battle of Vienna (1683), the Army of the Holy Roman Empire, led by the Polish King John III Sobieski, decisively defeated a large Turkish army, stopping the western Ottoman advance and leading to the eventual dismemberment of the Ottoman Empire in Europe. The army was half forces of the Polish–Lithuanian Commonwealth, mostly cavalry, and half forces of the Holy Roman Empire (German/Austrian), mostly infantry.
This period of renewed assertiveness came to a calamitous end in 1683 when Grand Vizier Kara Mustafa Pasha led a huge army to attempt a second Ottoman siege of Vienna in the Great Turkish War of 1683–1699. The final assault being fatally delayed, the Ottoman forces were swept away by allied Habsburg, German, and Polish forces spearheaded by the Polish king John III Sobieski at the Battle of Vienna.
