Context and Prelude to the Battle
Vienna, the capital of the Habsburg Monarchy, was under siege from 14 July 1683 by a vast Ottoman force commanded by Grand Vizier Merzifonlu Kara Mustafa Pasha. The Ottoman army, with strength estimates ranging from 100,000 to 300,000 men, aimed to capture Vienna and thus open the path to further expansion into Central Europe. The city’s defense was led by Ernst Rüdiger Graf von Starhemberg, who, despite being heavily outnumbered, managed to hold out against the siege for two months.

The Relief Force
The Holy Roman Empire and the Polish–Lithuanian Commonwealth, for the first time, cooperated militarily against the Ottomans. The relief force was led by John III Sobieski, King of Poland, who brought together a coalition army composed of various European states. Notably, the Polish contingent represented the Crown of the Kingdom of Poland, as the Lithuanian forces were delayed and arrived after the siege had been lifted.

The relief force led by John III Sobieski comprised around 70,000 men from Polish, Austrian, and German troops. The Polish contingent included the elite Winged Hussars, known for their formidable cavalry charges. Sobieski’s leadership and the surprise attack strategy played a crucial role in lifting the siege of Vienna. Image: Portrait of John III Sobieski.
