The House of Plettenberg is the name of the Westphalian noble family of the Uradel. It dates back at least to 1187, when Heidolphus de Plettenbrath was mentioned in a document by Philip I, the archbishop of Cologne.[1] Plettenberg-Wittem branch that ruled immediate Lodships of Meitingen and Sulmingen lost its sovereignty and became mediatised to Württemberg in 1806. This line of the family went extinct in 1813.
