How are Vienna and Ottoman Empire related?

Answer 1

Vienna is the capital city of Austria. During the medieval era of Europe, the Ottoman Empire was a very large and powerful country in the Middle East, and was difficult for the European countries to stop. In 1453 the Ottomans conquered the city of Constantinople and officially ended the Roman Empire. In less than 100 years, they had conquered the entire region known as the Balkans, right up to Vienna. So Vienna, in a way, marked the border between the Ottoman Empire and the rest of Western Europe.

In 1529 the Ottoman Empire made a major effort to conquer Vienna but failed, and historians generally consider that battle to have been the peak of their empire- they never again would be as powerful as they were up to that point. Again, in 1683, allied armies from Poland and Germany fought the Ottomans against near Vienna, defeating them and ushering in the long decline of the Ottoman Empire, which would ultimately end with the empire being dismantled after World War I.

During World War I, Austria and the Ottoman Empire were allies as part of the "Central Powers" along with Germany and Bulgaria. They fought together against the Allies (England, France, Russia until 1917, USA starting in 1917, and so on).
