The crusades mainly even happened because of the spread of Christianity in Rome and because of religious freedom.
The mission was to take back jerusalem at the command of the pope because it was a holy city and Jerusalem was sacred to Jews, Muslims and Christians. Here are some reasons people joined the crusades: -
1. To gain back a holy site from the Muslims because of devotion to their religion.
2. The pope told them that all the soldier’s sins would be forgiven.
3. To get wealthy
Hope this helped and if it did then kindly give me brainliest and have a nice day : )
