There’s a universal truth buried in here:

«Since the late tenth century, European churchmen had been fretting over what they could do to rein in the violence perpetrated by knights engaged in local feuds. The popes had direct experience of this through the Normans of southern Italy. But trouble was—or seemed to be—endemic. Two early attempts to impose Church discipline over unruly knights were known as the “peace movements”: the Peace of God (Pax Dei) and Truce of God (Treuga Dei). These were mass advocacy programs through which clergy tried to impress on fighting men the need to refrain from plundering churches, and killing, raping, maiming, or robbing civilians. Bishops tried to enforce the Peace by putting towns and regions under the Church’s explicit protection, and threatening God’s curse against trespassers who did their inhabitants harm. The Truce, meanwhile, named days and times of the year when fighting was forbidden.3 Both the Peace and the Truce of God proved widely popular among the common people, but they were not enormously effective. So among the many things that vexed Urban at the outset of his papacy was how to support moral censure with positive action.

Then, in 1095, an intriguing solution presented itself. In the first week of March, ambassadors from Alexios I Komnenos’s court in Constantinople appeared in the west.4 They tracked down Urban in the city of Piacenza, where he was holding an ecclesiastical council known as a synod. And they made him a proposal. According to the German chronicler Bernold of St. Blaisen, they “humbly implored the lord pope and all Christ’s faithful people to give [the Byzantines] some help against the pagans in defense of the holy Church, which the pagans had almost destroyed in that region, having seized that territory up to the walls of the City of Constantinople.”»

Every Western (movie) starts with the townspeople trying to enforce their rules against guns in town.

So here’s the truth: violent, armed men are not popular. They’re not the heroes.

Also: all that “Deus vult” horseshit is (excuse me, was) just an excuse for said armed, violent men. The First Crusade was just a way to ship those guys off, away from “here”, wherever “here” was.
