The Second Siege of Vienna (July 14-September 12, 1683) marks an important turning point in European history by its outcome with terrible repercussions for the Ottoman Empire
It was lifted on September 12 after the Battle of Kahlenberg, won by the Christians over the Turks. The Polish King John III Sobieski pushes back the Turkish Grand Vizier, Kara Mustafa, who arrived at the gates of Vienna at the head of 180,000 men.
Without the intervention of the King of Poland, the Habsburg monarchy would undoubtedly have collapsed and Islam, already established in the Balkans and in Hungary, would probably have taken root as far as Bohemia and southern Germany. This Polish victory marks the beginning of the European decline of the Ottoman Empire and the rise of Austrian power.
