To what extent was the First Crusade motivated more by religion, or other factors?

When answering a question such as this it is important to break it down and gleam its true essence. First, the question requires the student to recall other factors which could challenge religion's dominance as the prime motivator in the launching of the First Crusade. Second, it necessitates thought on whether a single one of these "other factors" could be just as motivating as religion, or whether they could only challenge religion's influence combined together. Finally, it encourages direct analysis between religion and these other factors in order to produce (in the student's own opinion) as to which factor is the most dominant. All the while students should also attempt to structure their paragraphs to the P.E.E.L. method – Point (argument by student), Evidence (to support said argument), Explanation (how evidence and point combine into acceptable statement), and Link (linking analysis back to the main question). With these considerations in mind the student should easily be able to formulate a high quality answer to the question. Such a answer would include content as follows:Potential "other factors": 1. The desire of Pope Urban II to end constant fighting between kings and princes of Europe by providing them with a common enemy in the form of the Seljuk Empire. 2. The potential to acquire new lands, monetary gains from looting, and prestige for Frankish nobles who took part in the Crusade. 3. The desire of Pope Urban II to bring the Byzantine Orthodox Church back in the Catholic fold through military/political aid via the First Crusade. Can "other factors" displace religion as dominating factor individually? Each reason has its own merits, yet are circumstantial due to being inapplicable to all the participants in the First Crusade. Which factor is the most dominant as motivation for the First Crusade? This segment is up to the student, but for the sake of this question I personally believe religion remained the most dominant, with remission of sins being a proverbial “golden ticket” into heaven for both the Frankish nobles and soldiers who wore the cross.
