Siege of Vienna

The Siege of Vienna in 1529 was the first attempt by the Ottoman Empire, led by Suleiman the Magnificent, to capture the city of Vienna, Austria. The siege signalled the pinnacle of the Ottoman Empire's power and the maximum extent of Ottoman expansion in central Europe. Thereafter, 150 years of bitter military tension and reciprocal attacks ensued, culminating in the Battle of Vienna of 1683, which marked the start of the 15-year long Great Turkish War.
