With the Taliban coming back, and each time before that with ISIL, it always reminded me of the crusades. So my question can be general or specific based on examples below.
Did the soldiers or new government tear down, destroy, or deface mosques, artifacts, or other non-Christian important monuments?
Were the local Muslim population, who stayed, able to lead normal lives (go to mosques, wear their religious clothing, celebrate religious festivals, etc.)?
I have a couple of previous comments that might be helpful:
The Histories of Religious Minorities Floating Feature about minorities in the crusader states - this is about the local Christian and Jewish populations too, but also about the Muslim inhabitants
and How were Muslim pilgrims/residents treated within the Kingdom of Jerusalem?
The crusaders converted the al-Aqsa mosque in Jerusalem into a Christian site (it was the headquarters of the Knights Templar), Muslims now had to pay the same jizya tax to their new Christian rulers that Christians used to have to pay to them, and there was the extra danger that they might be randomly attacked/enslaved...but otherwise, the crusaders didn't really want to interact with Muslim people at all, so the Muslims were typically completely ignored.
