Werden (abbot Heribert II, 1197-1226, who received privileges from Otto IV at a date not pinned) and the convent of Essen are imperial churches on the lower Ruhr whose small territories are governed in practice through their advocate.
Both advocacies went to the Altena line at the division of 1160; Arnold of Altena has held Werden since 1180. The advocacy is the lordship: courts, dues and the protection of the abbeys' people.
