Is the desire to take control of jerusalem away from muslims a religious reason, a politcal reason or an economic reason?

This is a religious reason.

This desire was the motivation of the crusaders who wanted to bring Jerusalem, and other sites that witness the life of Jesus, into the hands of the Christians, and away from the Muslims, so that Christians can worship in this sites.
