Gottesfreunde
In 1338 or 1339 the Dominicans were exiled from Strasbourg as a result of the tensions between Pope John XXII and Lewis of Bavaria. Tauler spent his exile (c. 1339–1343) in Basel. Here, he became acquainted with the circles of devout clergy and laity known as the "Friends of God" ("Gottesfreunde"). Tauler mentions the Friends of God often in his sermons. Evidence for further connections with this group is found in the letters exchanged between the secular priest Henry of Nördlingen and his spiritual friend, the Dominican nun Margaret Ebner. Through Henry, Tauler also became acquainted with Mechthild of Magdeburg's "Flowing Light of the Godhead".
