Waldenses, also spelled Valdenses, French Vaudois, Italian Valdesi, members of a Christian movement that originated in 12th-century France, the devotees of which sought to follow Christ in poverty and simplicity. In modern times the name has been applied to members of a Protestant church (centred on the Franco-Italian border) that formed when remnants of the earlier movement became Swiss Protestant Reformers.

Early Roman Catholic and Waldensian sources are few and unreliable, and little is known with certainty about the reputed founder, Valdes (also called Peter Waldo, or Valdo). As a layman, Valdes preached in Lyon (1170–76), but ecclesiastical authorities were disturbed by his lack of theological training and by his use of a non-Latin version of the Bible. Valdes attended the third Lateran Council (1179) in Rome and was confirmed in his vow of poverty by Pope Alexander III. Probably during this council Valdes made his Profession of Faith (which still survives); it is a statement of orthodox beliefs such as accused heretics were required to sign. Valdes, however, did not receive the ecclesiastical recognition that he sought. Undeterred, he and his followers (Pauperes: “Poor”) continued to preach; the archbishop of Lyon condemned him, and Pope Lucius III placed the Waldenses under ban with his bull Ad Abolendam (1184), issued during the Synod of Verona.

Thereafter, the Waldenses departed from the teaching of the Roman Catholic church by rejecting some of the seven sacraments and the notion of purgatory. Their views were based on a simplified biblicism, moral rigour, and criticism of abuses in the contemporary church. Their movement, often joined to and influenced by other sects, spread rapidly to Spain, northern France, Flanders, Germany, and southern Italy and even reached Poland and Hungary. Rome responded vigorously, turning from excommunication to active persecution and execution. Though the Waldenses confessed regularly, celebrated communion once a year, fasted, and preached poverty, they repudiated such Roman practices as prayers for the dead and the veneration of saints, and they refused to recognize secular courts because they did not believe in taking oaths.

In the early 13th century a number of Waldenses returned to orthodoxy; by the end of the century persecution had virtually eliminated the sect in some areas, and for safety the survivors abandoned their distinctive dress. By the end of the 15th century they were confined mostly to the French and Italian valleys of the Cottian Alps.

A second period in their history began when the French reformer Guillaume Farel introduced Reformation theology to the Waldensian ministers (barbes) in 1526. The Waldenses raised questions concerning the number of sacraments, the relationship between free will and predestination, and the problem of reconciling justification by faith with the scriptural emphasis on the necessity of good works. At a conference at Cianforan in 1532 most Waldenses accepted secular law courts and celibacy for their barbes and agreed to accept only two sacraments (baptism and Holy Communion) and the doctrine of predestination as presented by the Protestants in attendance. By further adapting themselves to Genevan forms of worship and church organization, they became in effect a Swiss Protestant church. Years of persecution continued, however, before they received full civil rights in 1848.

During the second half of the 19th century, Waldensian emigrants arrived in Uruguay and later moved from there to the United States. There, strengthened by arrivals from France and Switzerland, they established small communities in Missouri, Texas, and Utah and, most importantly, around Valdese, in Burke county, N.C., now a thriving industrial town whose population of about 3,000 is still largely Waldensian.

Today the Waldenses are governed by a seven-member board, called the Tavola (“Table”), elected annually by a general synod that convenes in Torre Pellice, Italy.
