The first Bishop of Münster, Liudger established Werne as a parish by erecting a chapel in the southern parts of the Dreingau ("in pago dreginni"). He acted on orders of Charlemagne who, having finally brought the region under the fold of Francia following the conclusion of the Saxon Wars, was eager to press on with Christianization. The Latin text of the oldest preserved document ("in villa quae dicitur werina"), which dates from 834 and is being kept at the Leiden University Library, indicates that by this time a village had already formed around the chapel.
