The Poor Catholics (Pauperes Catholici) were an early Catholic mendicant order, organized in 1208 and of short duration. Recruits were taken from the Pauperes Lugdunenses (the original name of the Waldensians); the distinguishing name was given by Pope Innocent III.
The background was the growth of the Albigensians in Provence. Innocent III complains bitterly, in a letter to the bishops, saying that the people are hungry for the Bread of Life, but that there is no one to break it for them. Public preaching, exclusively in the hands of the bishops, had become a rare event. Having thus far failed in its attempts to suppress the heresy, on account of the inadequate methods of its missionaries, the Catholic Church now adopted a new method, preaching the word of God and leading a life of resignation and evangelical poverty. Through the missionary activities of Bishop Diego of Osma and St. Dominic, a small group of Waldenses, under the leadership of Duran of Huesca (Spain), was won back to the Catholic Church during a religious discussion at a meeting held at Pamiers (France) towards the end of 1207.
Innocent III gave them, initially seven in number, a constitution by which they could retain their former rule of life. Aside from this they had to make a profession of faith. It represented the doctrine of the Church relative to all current heresies, and was intended, not only to free their minds from all heretical tendencies and subject them to the authority of the Church, but also to offer them a guide according to which they could enter upon missionary activities with a series of formulated truths giving them a clear outline of their faith and absolute certainty in their work. After having promised allegiance to the pope and the doctrines of the Church, they entered upon their mission in the beginning of 1208. They were active, not only through Southern France, but as far as Milan where they founded a school in 1209 to gather and educate recruits for their order. Three years later, 1212, a group of penitents placed themselves under their spiritual direction. Within four years of their foundation they extended their activities over the Dioceses of Béziers, Uzès, Nîmes, Carcassonne, Narbonne, Taragon, Marseilles, Barcelona, Huesca, and Milan.
