Well, yes, that’s a bit obvious, innit ? No religion, no Pope ; no Pope, no decree across Christendom.
Yes and no. Depends on what you refer to for “people”.
For Kings and high profile barons, avoiding being on the Pope’s shitlist and scoring brownie points by acquiescing to his wishes was a powerful incentive, too. I’m not sure this was already the case for the first one, but the Vatican also loaned lots and lots of moolah to help finance the war effort later on as well - another bonus, especially when you’re in position to skim a bit, or a lot, off the top.
What factors led commoners, men-at-arms, petty nobles and fanatics to join up vary from crusade to crusade, region to region, person to person. You really can’t chalk it *all *to blind religion.
Look, I’m not saying there wasn’t a religious aspect to the Crusades. That would be absurd, even for me ;). But the higher up the Crusade counter you go, the less they had to do with religion at all.
Although the alternative history scenario you propose is interesting. I really wonder how European history would have unfolded, without the unifying factor of Catholicism.

Nonsense, I think you seriously underestimate the power of the Church over medieval minds. Whether religion was the casus belli or just the major tool used to propagate the conflict it makes no difference, religion was at the center so it’s a religious war.

Nonsense right back atcha. People of the Middle Ages might have been lacking in accumulated knowledge, they mightn’t have stood on the shoulders of giants, but they weren’t stupid. Nor were they religulous automatons played by their priests. Especially the nobles, who were for the most part well educated, and often had minds like corkscrews.
The Church had enough symbolic power to nudge events, sure. It also had money to nudge events. But the Pope really wasn’t Big Brother, the All Controling Man-Behind-The-Crowns, strongarming the shaking masses to his iron will using his ju-ju threats. The Fourth Crusade alone is a testament to that.
