What “taking the cross” meant
A crusade was not just an army marching under a banner. It was a religious undertaking made by individuals who promised to go. A person who made the promise was said to “take the cross”, often receiving a cloth cross to sew onto clothing as a visible sign. The vow made the person a crusader in law and in the eyes of the church, with spiritual rewards and legal protections, and also with obligations that could be hard to escape.
The pope as preacher
Pope Urban II launched the movement in 1095 with a sermon at Clermont, after which the call was spread across France and further. Later popes did not leave this to chance. They issued letters, appointed legates and encouraged local preachers to travel through towns and villages and stir up interest. Preaching might include a sermon in the local language, public ceremonies and the distribution of crosses. Records of what was actually said are patchy, and the surviving wording often comes from chroniclers who wrote later. Historians therefore treat the exact words of the Clermont speech with caution.
Indulgences
The central spiritual reward was an indulgence, which in this period meant a remission of the penance owed for sins that had already been confessed. Over time the wording changed. The earliest versions seem to have focused on the hardship of the journey as a substitute for penance. Later versions were more elaborate, and by the thirteenth century popes spoke in broader terms about forgiveness for those who took part, and in some cases for those who gave money in place of going.
It is easy to misread the idea. An indulgence was not a license to sin or a purchase of salvation. In church teaching it depended on genuine repentance. How well ordinary people understood the fine points, and how far preachers stretched them, is a different question, and contemporary critics did complain about abuse.
Legal and practical protections
A crusader was usually promised protection for family and property while away. Debts might be suspended or interest limited, and the church claimed jurisdiction over matters affecting crusaders. These benefits were useful but not always respected in practice. Vows could also be commuted. Someone too old, sick or poor could be released from going in return for a donation, which brought in money for the cause.
Breaking a vow was treated seriously. Those who turned back without permission could be pressured by the church to go again, and some were disgraced in the eyes of their neighbors.
Who answered
The picture of an army made up wholly of armored knights is incomplete. Knights and their followers formed the core of the fighting men, and often traveled in groups bound by ties of lordship and kinship. But sources also mention poorer pilgrims, servants, clergy, craftsmen and women. Some women went as wives or relatives, and some provided support in camps. The size of these crowds is uncertain, since medieval writers were prone to round and exaggerated numbers.
Early in the movement, crowds led by preachers set out with little training or equipment. The popular expeditions of 1096, often grouped under the name People’s Crusade, ended badly, and the same period saw attacks on Jewish communities in the Rhineland. Church leaders at the time criticized some of this violence, though not all of them.
Motives and mixed reasons
Why did people go? Sincere belief was very likely strong, along with fear for the soul, love of Jerusalem and duty to a lord. Adventure, land and a hope of improving one’s position probably played a part for some, as did family tradition. Chroniclers often describe a crusader’s motives in solemn religious terms, which limits what we can learn. A reasonable view is that motives varied from person to person and could be mixed in one individual.
From promise to practice
The vow shaped everything that followed, including how armies were raised, how they were funded and how they were seen by those at home. It tied warfare to penance, and that link is one reason the crusades are described as holy war. The idea was not static, and by the thirteenth century crusade preaching was being used against heretics and political enemies of the papacy as well as against Muslim rulers.
