are you actually a historian or just some guy who watched some youtube documentaries. Crusades failed, and that's a fact, i don't know what else to say. They did capture a tiny area but it was later recaptured and their goal was not achived.I am an historian, and you are simply a really not smart person. Over 200 years, pilgrims could visit Jerusalem, for over 500 years Constantinople endured and for almost 600 years people in Europe could live their lives without a big Muslim invasion.
This is the first sentence from the wiki page on crusades, "The Crusades were a series of religious wars initiated, supported, and sometimes directed by the Latin Church in the medieval period. The term refers especially to the Eastern Mediterranean campaigns in the period between 1096 and 1271 that had the objective of recovering the Holy Land from Islamic rule." Now you still refuse to believe that crusades were a thing?Uhmn... no. The first crusade was the first crusade. the second the second. the third the third. there was no "bigger crusade". But to be fair, yes, their was an overarching goal of all crusades, which was "to check the spread of Islam, to retake control of the Holy Land in the eastern Mediterranean, to conquer pagan areas, and to recapture formerly Christian territories " (https://www.britannica.com/event/Crusades) and that failed in the end, at least until the end of the first world war. That doesnt mean that some of them acchieved what they wanted.
