# Siege of Vienna

> The Ottoman attempt to take Vienna and its failure marked the definitive limit of Islamic expansion into Europe and triggered the empire's long decline.

In September 1683, Ottoman forces under Kara Mustafa Pasha had Vienna surrounded and starving after a two-month siege. A relief army led by Polish King John III Sobieski broke through on 12 September, routing the Ottomans in what became one of history's most decisive military reversals—and a turning point that ended Ottoman expansion into Europe.

## Summary

The Battle of Vienna took place at Kahlenberg Mountain near Vienna on 12 September 1683 after the city had been besieged by the Ottoman Empire for two months. The battle was fought by the Holy Roman Empire, led by the Habsburg monarchy, and the Polish–Lithuanian Commonwealth, both under the command of Polish King John III Sobieski, against the Ottomans and their vassal and tributary states.
