OTD 1683 the Battle of Vienna took place on Kahlenberg Mountain, near Vienna, after the city had been besieged by the Ottoman Empire for two months. The battle was fought by the Hapsburg Monarchy, the Polish-Lithuanian Commonwealth and the Holy Roman Empire, under the command of King John III Sobieski. The battle marked the first time that the Commonwealth and the Holy Roman Empire had cooperated militarily against the Ottomans, and is often seen as a turning point in history, after which 'the Ottoman Turks ceased to be a menace to the Christian world'. An ancestor, Franciszek Tuchołka, was one of the 'Winged Hussars' who charged. His arms are amongst those of the 102 noblemen who took part in the Battle which are displayed in the Sobieski Chapel on Kahlenberg. #siegeofvienna #battleofvienna #kahlenberg #franciszektuchołka #jansobieski #sobieskichapel #ottomanempire #wingedhussars #poland #hapsburg #holyromanempire (at Kahlenberg)
