The Siege of Vienna was a pivotal moment in the early 16th century as the Ottoman Empire, under the leadership of Sultan Suleiman I, sought to expand its territory into Central Europe. The siege began in September, with the Ottoman forces amassing a large army to capture the city, which was then a vital stronghold for Christian Europe. The Habsburg rulers of Austria recognized the existential threat posed by the Ottomans and fortified Vienna's defenses in anticipation of the assault. The city, surrounded and besieged, held out due to the determined defense led by figures such as Count Nikolaus von Salm and the resolute citizens, who rallied to protect their homes and lands. As the siege dragged on, the weather turned severe, and supply lines for the Ottoman forces grew strained. The defenders, taking advantage of these circumstances, executed several sorties against the besieging troops and cut off their supplies. By mid-October, as morale diminished within the Ottoman ranks, the Austrians launched a counter-offensive that decisively shattered the invading forces. This unexpected turn of events marked the end of the siege and established Vienna as a bastion against further Ottoman incursions into Europe for decades to come.
