Sobieski's Victory refers to the decisive battle fought on September 12, 1683, during the Battle of Vienna. The conflict was between the forces of the Ottoman Empire and a coalition led by King Jan III Sobieski of Poland. The battle was crucial in halting the Ottoman advance into Europe and is often seen as a turning point in the struggle between Christian and Muslim powers. King Sobieski's troops, numbering around 70,000, joined forces with the Holy Roman Empire and other allies to lift the siege of Vienna. The victory not only saved the city but also marked the beginning of the decline of Ottoman influence in Europe.
