Why did Ottoman Türkiye, which had been strong for centuries, end up in Vienna?

In the 17th century, Turkey's domestic development and stability led to a rapid increase in population. Most of Türkiye's territory is desert. Türkiye's population reaches 30 million. The pressure on land has increased significantly, resulting in a decline in fiscal revenue. The result of the inability to pay the demobilized personnel wages and land was a large-scale rebellion by these mercenaries, and the location of the rebellion was in Asia Minor, its political heartland. The war and the post-Party dictatorship caused the Ottomans to miss the opportunity of the Thirty Years' War.

At this time, the Ottoman Empire could not continue its attack. The stagnation of expansion made the level of the Sipaxi cavalry in the fief worse and worse. This has also led to increased population pressure. In the end, the Koprulu family took over as the grand vizier, allowing the Ottoman Empire to have its last renaissance before the recession. This was the last revival of the Ottoman Empire before the economic recession. They were able to expand again because the interests of the guards, rear party members, and bureaucrats were well coordinated. For the Austrian border guards, the threat of a resurgent Ottoman Empire remained great. After all, there is no gap in technology.

There are many reasons for the serious setback in Vienna, one of which is also related to Turkey being attacked on both sides. The reason why Türkiye has failed to restore the Iranian plateau in the Middle East has to do with the powerful enemies there. At that time, the existence of the Timurid Empire blocked Türkiye. At the beginning of the 16th century, 20 years before Turkey attacked Vienna, the rise of the Fourth Persian Empire on the Iranian Plateau also made the Turks very anxious. However, this was only one aspect. In fact, it did not reflect the reasons for the failure of Vienna in Turkey. . The main reason is that the prosperity that the belligerent Ottoman Empire gained through wars and plunders has slowly declined. The resources and technology of the three continents that it once relied on and the prosperity it gained through the attack on Western Europe have been in constant war with many countries. Make enemies and fall into endless long-term wars from which you cannot extricate yourself.

The Ottoman army, which was constantly defeated by the coalition forces, began to fight in disorder. The coalition forces pursued the victory and began to break through the Ottoman army's defense lines one after another. Finally, the coalition forces attacked the Ottoman army's large-scale cavalry and dealt the final blow to the defeated Ottoman army. In just one day, the reinforcements defeated the Ottoman army and won the siege of Vienna.
