In the wake of taking Constantinople, the Ottoman Empire would spend the next few centuries expanding its size, power, and influence, bumping up against Eastern Europe and becoming one of the world’s most important geopolitical players. It would take repeated efforts by various European coalitions to prevent a complete Ottoman takeover of the continent, and one of the most important battles among those efforts took place at Vienna in 1529.
At the time, the Ottomans were led by one of their most famous sultans, Suleiman the Magnificent, and different chroniclers have analyzed Suleiman's behavior in different ways. There is a plethora of opinions as to his motives for attempting the takeover of Vienna, a well-guarded city far away from his empire's center. Had he intended to conquer the whole of the Holy Roman Empire? Had he intended to strengthen his borders? Had he acted in accordance with King Francis I’s needs in the West? No matter the reason, Suleiman did not halt in his advances, despite the fact circumstances were not favorable for the Ottomans. The summer rains had already begun when he set out for Vienna, making most of the roads inaccessible both for cavalry and moving the heavy pieces of artillery needed for a successful siege. The camels brought from Anatolia proved too sensitive for the cold, constant rain and died in large numbers, and many of the soldiers shared the same fate.
Modern historians speculate as to why Suleiman persisted with the siege even though the Ottoman forces were evidently weaker than the forces in Vienna upon their arrival. As an experienced, strategic warrior, it is most likely he realized his disadvantage and the full scale of his potential losses. It was also probable that the last burst of attacks was merely a means with which to weaken the city walls for a future siege. The second attempt, in 1532, was met with the same mix of bad luck and good defense, and Vienna marked the limit of their advances
