“The Western Church splits and when the Turks are invading Vienna in 1683, some Hungarian actually fight on the side of the Turks against their Christian brethren. Luckily this does not result in a Turkish win, or else Rome too would be under the yoke of Islam”
What about the defeat at Budapest under Suleyman, etc. By 1683 - they were already on the decline and this was their last ditch attempt to take Vienna. They failed because of the collaboration between the Poles and Vienna.
The first invasion of Vienna was far more serious and resulted in the subjugation of Hungary.
The defeat at Buda (Pest was a separate town across the river) in 1686 was due to the victory at 1683. In 1683 we had Christians fighting on the side of the Ottoman Caliph. THAT is what i’m pointing out..
