The Siege of Vienna refers to two significant military conflicts in the 17th century, the first occurring in 1529 and the second in 1683. In both instances, the city of Vienna, the capital of Austria, was besieged by the Ottoman Empire. The 1683 siege is particularly notable as it marked a turning point in the struggle between the Ottomans and European powers. During the 1683 siege, the Ottomans aimed to expand their territory into Central Europe. However, a coalition of European forces, including the Holy Roman Empire and the Polish-Lithuanian Commonwealth, successfully lifted the siege. This victory is often seen as a crucial moment in halting Ottoman expansion into Europe.
