The Second Siege of Vienna and the Great Retreat
On the timeline · around 1683 CE ·
What happened
In 1683 the Ottomans besieged Vienna a second time, only to be routed when a Polish-led relief army charged down from the hills. It was the beginning of a long retreat from central Europe.
Why it matters
The failure at Vienna turned the tide permanently: for the first time the Ottomans began losing large territories rather than gaining them.
