That's ridiculous. The crusaders never got anywhere near Bagdad, Persia, or Mecca. They only attempted to retake Christian lands that muslims had taken by force of arms. Just about everything the Muslims had was taken by military force. Modern Muslims take pride in Mohamed's skill at combined military+economic conquest. Meanwhile the Crusaders had never done anything remotely like that, so naturally their attempts were a mess. They had troops who were expecting to fight people with literal tails and horns growing from their heads. When they arrived and found that they couldn't tell friend from foe, confusion lead to atrocities.HHunter1 wrote: ↑Mon Sep 11, 2023 12:28 pmOh, and if your wondering why the Muslim world suddenly stopped being a technologies and progressive leader, it was the Crusades. Not falling behind. Not ignoring advances. Its hard to be a pillar of civilization when armed groups of plague carrying people raid and pillage your Libraries and places of learning every couple of years. I mean Harvard is a prestigious University but I think the quality of the education there would drop dramatically if randomly every few years it was pillaged by barbarian raiders.
You've also got the dates wrong. By the time the muslim empires started declining, (1400's) the serious crusades were over, and what was left were token efforts that didn't accomplish much.
