From my reading of history, wasn’t the LAST CRUSADE the Spanish attack on England in 1588? The Spanish tried again a few years later and again failed to conquer England.
It was generally called the "Great Eastern Crisis" part of which was the Herzegovina Uprising of 1877. In which 200,000 christian were fugitives as a result the Ottoman Empires Jizya tax increases. Christians were still considered to be Dhimmi or second class citizens under Islamic rule. This spread into the Serbo-Turkish War.
It was only logical for the Austria-Hungary to stop the war at the boarders.
After Austria took over the area this caused issues with Serbia you know the rest of the story.
I understand your point but it is similar to Serbia attacking Austria when their real that was Islam. Philip II was an idiot
