The Congregation of Windesheim is a branch of the Augustinians. It takes its name from its most important monastery, which was located about four miles south of Zwolle on the IJssel, in the Netherlands.
This congregation of canons regular, of which this was the chief house, was an offshoot of the Brethren of the Common Life and played a considerable part in the reform movement within the Dutch and German Catholic Church in the century before the Protestant Reformation.
The Brethren of the Common Life, who did not form an order or congregation strictly so called, had become obnoxious to the mendicant friars and the object of their attacks. To remedy this, their founder, Gerard Groote, advised on his deathbed in 1384 that some of the brethren should adopt the rule of an approved Order. His successor, Florence Radewyns, carried this advice into effect. Six of the brethren, carefully chosen as specially fitted for the work, among them John, elder brother of Thomas a Kempis, were sent to the monastery of Eymsteyn (founded 1382) to learn the usages of the canons regular. In 1386, they erected huts for a temporary monastery at Windesheim, and in March of the following year commenced the building of a monastery and church, which were consecrated by Hubert Lebene, titular Bishop of Hippo and auxiliary bishop of Utrecht, on 17 October 1387. At the same time the six men took their vows. They adopted the apostolate of hospitality.
Under Johann Vos, the second prior (1391–1424), the number of canons greatly increased and many new foundations were made. The first of these were Marienborn near Arnhem and Niewlicht near Hoorn (1392). The congregation was approved and received certain privileges from Pope Boniface IX in 1395. Their constitutions, added to the Rule of St. Augustine, were approved by Pope Martin V at the Council of Constance.
