Yep that’s right. First Crusade didn’t happen until almost 400 years of Jihad had passed from the gates of Paris, to Spain, to the Indian sub-continent, China, Asia minor - Christian, Jewish, Zorastrian, Hindu civilizations uprooted, dhimmiized, subjugated to the Jihad relentlesly. It was in fact the Eastern church and the Byzantine empire call for help as the Seljuk Turks were knocking at their doorstep already having subject some and cleansed other communities on their Jihad path, which caused the Western Church to bring together a force to counter the Jihad. Again, almost 400 years before the first Crusade ever appeared. Having said that, the Crusades in the end were not good particularly as one of them even turned on the Eastern Church and Byzantine empire by sacking Constantinople which act was probably responsible for the eventual successful Jihad against Constantinople by the Turks.
Yep. We should demand Constantinople back.
