The Pope thought the crusades would help end fighting among what group of European landowners?

The Pope believed that the Crusades would help end fighting among the nobility, specifically the feudal lords and landowners of Europe. By redirecting their martial energies towards a common external enemy in the Holy Land, the Crusades aimed to reduce internal conflicts and unite these factions under the banner of a religious cause. This was seen as a way to promote peace and stability within Christendom by channeling their ambitions outward.
