In 1529, the Ottoman Empire, led my Suleiman was at the height of its power. It had defeated most of Hungary and all that really stood in its way and stopped it from continuing on into parts of the Holy Roman Empire was Vienna, which was a poorly defended city. Suleiman and his army led siege to the great city with hundreds of thousands of troops. The defenders, however, managed to turn him back. Although he would try again later, he would never come as close to breaking into the Holy Roman Empire. In many ways this would be the high point of the Ottoman Empire. It would be increasingly encroached, and finally defeated by the Europeans. Who knows how history would have played out if the Ottomans had been able to keep control of Hungary and also to take Vienna? They could have used this city as a base from which to attack Germany and Italy.
