Answer:
Catholic church would not have advocated for the crusades because they knew the long term result of them because crusades divided the land in between Christian and recaptured their holy land from the authority of Muslim. Roman catholic church suffered due to the crusades because it supported Protestantism.
Step-by-step explanation:
Crusades worked in favor of Christianity but not for the Roman Catholic church. They supported Protestantism. They started war with Muslim for again gaining their holy land which was once captured by Muslim. But crusades promoted autocracy where king had the supreme power to control everything.
Due to the crusades battle was started between different religious group in Western Europe and the whole country suffered for it and many soldiers killed there. All the Muslim occupied territories again regained by crusades.
