September 27th: Suleiman I, known as "The Magnificent" and also Sultan of the Ottoman Turkish Empire as well, attacked the city of Vienna in 1529.

The Battle of Vassilika in 1821 marked an early turning point in the war.

The Turkish Ottoman Empire laid siege to Vienna for the first time on September 27, 1529. However, Fernando I, Emperor of the Holy Roman Empire, won the support of Carlos V of Spain and the Prussians so he was able to repel the Turkish invasion in the Vienna streets.

Suleiman laid siege to Vienna in 1529.

Three years later, in 1532, the Turks attacked again to Vienna. If they had defeated Vienna, they would have taken over Central Europe. Austria was very weak.

Suleiman ruled from 1520-1560. In his time was regarded as the most significant ruler in the world, by both Muslims and Europeans. His military empire expanded greatly both to the east and west, and he threatened to overrun the heart of Europe itself. 

Carlos V of Spain, who was the brother of Ferdinand I, Archduke of Austria; King of Hungary and Bohemia; and Emperor of the Holy Roman Empire, had to send Spanish troops under the Duke of Alba to beat back the armies of Suleiman. Ferdinand of Austria and Carlos of Spain were brothers and sons of Philip "The Handsome".

One hundred and fifty years of hostilities between Turks and Germanic ended in the Battle of Vienna. The Turks captured Constantinople, now Istanbul, and seized Eastern Europe.

They wanted to capture the heart of Europe and else. Suleiman wanted first to become the king of Hungary, and then absorb the Holy Roman Empire.

Sultan Suleiman I (1494 – 1520 – 1566) “The Magnificent” and “The Law Giver” reigned for 46 years from 1520 as the tenth and greatest ruler of the Ottoman Empire. His father, Selim “the Grim”, who ruled from 1512 to 1520, had conquered Egypt and become the first Ottoman Sultan to also take the title of Caliph.
