feudalism declined during the crusades because\no the catholic church called for its end.\no the nobilitys…

Brief Explanations:

During the Crusades, many nobles went on Crusades, and when they died or faced financial difficulties, their wealth and land often passed to the monarch. This weakened the feudal - based power structure of nobles and thus contributed to the decline of feudalism. The Catholic Church did not call for the end of feudalism. The Catholic Church did not take control of European governments in a way that directly led to feudalism's decline. There was no large - scale uprising of knights against their kings that was a main cause of feudalism's decline during the Crusades.

Answer:

the nobility’s wealth and land passed to the monarch.
