Why did peasants give up their work to go off and fight under the leadership of Peter the Hermit?

Peasants were motivated to join Peter the Hermit and participate in the First Crusade due to a combination of religious fervor and the promise of spiritual rewards, such as forgiveness of sins and the hope of salvation. The idea of reclaiming the Holy Land from Muslim control resonated deeply with their faith, prompting many to abandon their daily struggles for a higher purpose. Additionally, social and economic pressures at home may have contributed to their willingness to join the movement, seeking a sense of adventure and community in the quest.
