The Black Death

The Flagellant Movement

In the spring and summer of 1349, bands of men and women marched through the cities and towns of Europe, stripped to the waist, whipping themselves with scourges studded with iron spikes, and singing hymns of penitence. They called themselves the Flagellants — the Brothers of the Cross — and they believed that their public acts of self-mortification could appease God’s wrath and end the plague. The movement, which originated in the German-speaking lands and spread across much of Central and Western Europe, was one of the most dramatic social phenomena of the Black Death era.

Origins and Development

The practice of religious self-flagellation was not new in the fourteenth century. It had precedents in the ascetic traditions of the early Church and had been practised by individual penitents and religious communities for centuries. However, the organised, public Flagellant movement that emerged during the Black Death was a new phenomenon, born of the specific anxieties and terrors of the pandemic.

The movement began in the spring of 1349 in the German-speaking lands, possibly in the region of Thuringia or the upper Rhine. Small groups of penitents began to march from town to town, performing public acts of self-mortification in market squares and churchyards. The practice attracted followers rapidly, and within weeks, bands of Flagellants were appearing across the Rhineland, Bavaria, and the Low Countries.

The movement was led by charismatic preachers — often laymen rather than ordained clergy — who claimed to have received divine revelations. The most prominent of these leaders preached that the plague was a punishment from God for human sin, and that only through collective penance could the divine wrath be averted. The Flagellants’ public processions were designed to demonstrate the sincerity of their repentance and to inspire others to join them.

The Flagellant Ritual

The Flagellant ritual was highly structured and deeply theatrical. A band of Flagellants — typically numbering between fifty and several hundred — would enter a town in procession, dressed in white robes marked with red crosses. They would proceed to the main church or market square, where they would strip to the waist and form a circle.

The leader would then read aloud a letter that the Flagellants claimed to have received from heaven — a letter supposedly brought by an angel to the Church of the Holy Sepulchre in Jerusalem — in which God declared that the plague was a punishment for human sin and that thirty-three and a half days of penance (corresponding to the years of Christ’s earthly life) would suffice to avert His wrath.

The Flagellants would then whip themselves with scourges — leather thongs studded with iron spikes or knots — while singing hymns of penitence. The flagellation was performed ritually, with each participant striking himself in turn, and the blood that flowed from the wounds was considered a form of sacrifice that mirrored Christ’s suffering. The ritual was intensely emotional, and spectators often wept, confessed their sins, and joined the movement.

The Flagellant movement spread rapidly through the German-speaking lands, the Low Countries, and parts of France. Bands of Flagellants appeared in Strasbourg, Basel, Cologne, Mainz, and dozens of smaller towns. The movement attracted followers from all social classes — peasants, artisans, merchants, and even some nobles and clergy — though the majority were drawn from the labouring and artisan classes.

The popular response to the Flagellants was mixed. Many people were deeply moved by the spectacle of public penance and saw the Flagellants as holy men whose suffering might indeed avert the plague. Crowds gathered to watch the processions, and many spectators confessed their sins, gave alms, and asked the Flagellants to pray for them.

However, the movement also generated fear and suspicion. The Flagellants’ claim to have received a letter from heaven challenged the authority of the Church, which held that divine revelation was mediated through the clergy and the sacraments. The movement’s leaders, who were mostly laymen, effectively set themselves up as alternative religious authorities, bypassing the established ecclesiastical hierarchy.

Antisemitism and Violence

The Flagellant movement became closely associated with the persecution of Jewish communities during the Black Death. Flagellant preachers accused Jews of poisoning wells to spread the plague and called for their destruction. In several towns, Flagellant processions were followed by attacks on Jewish quarters, and the movement provided a vehicle for the expression of antisemitic violence that was already widespread.

The massacres of Jews in Strasbourg (February 1349), Basel (January 1349), and other Rhineland cities were linked to the activities of Flagellant bands. The Flagellants’ accusation that Jews were responsible for the plague gave religious sanction to violence that was motivated by a complex mixture of theological prejudice, economic resentment, and the search for scapegoats.

Pope Clement VI condemned the Flagellant movement in part because of its association with antisemitic violence. His two papal bulls of 1348, which defended the Jews against the accusation of well-poisoning, were directed as much at the Flagellants as at the secular authorities who had permitted or encouraged the massacres; he condemned the Flagellant movement itself in a separate bull, Inter sollicitudines, in October 1349.

The Church’s Response

The Church’s initial response to the Flagellant movement was cautious. Some bishops and priests welcomed the Flagellants, seeing them as genuine penitents whose devotion might indeed help to avert the plague. Others were suspicious of the movement’s unauthorised leadership, its claims of divine revelation, and its challenge to ecclesiastical authority.

By the autumn of 1349, the Church had moved decisively against the movement. Pope Clement VI issued a bull condemning the Flagellants as heretical, and the secular authorities in most regions cooperated in suppressing the processions. The movement’s leaders were arrested, and some were executed. The bands of Flagellants were dispersed, and the practice of public self-flagellation was prohibited.

The Church’s suppression of the Flagellants reflected its concern about the movement’s theological implications. The Flagellants’ claim that their penance could avert the plague implied that human suffering could substitute for divine grace — a position that bordered on the heretical. The movement’s lay leadership challenged the Church’s monopoly on religious authority, and its association with antisemitic violence made it a source of social disorder.

Legacy and Later Movements

The Flagellant movement of 1349 was suppressed, but it did not disappear entirely. Small groups of Flagellants continued to practise in secret, and the movement resurfaced sporadically in the following decades. In Italy, the Flagellant tradition was institutionalised in the form of confraternities — lay religious organisations that practised self-flagellation as part of their devotional life. These confraternities, which were sanctioned by the Church and integrated into the established religious order, were very different from the unauthorised, apocalyptic movement of 1349.

The Flagellant movement remains one of the most striking expressions of the collective anxiety generated by the Black Death. It illustrates the depth of the crisis of faith that the pandemic provoked, the willingness of ordinary people to take religious initiative when established institutions proved inadequate, and the dangerous intersection of religious fervour and social violence.
