Styrum

Styrum (German pronunciation: [ˈʃtiːʁʊm]; sometimes spelled "Stirum") was an immediate lordship in the Holy Roman Empire, located in Mülheim an der Ruhr, North Rhine-Westphalia, Germany. It held no seat in the Diet and was circumvened by the lordship of Broich.

The exact date of construction of its castle is unknown. Styrum was already prosperous in Frankish times before Charlemagne (late 8th century). In 1067 Styrum was given to the Abbacy of Kaiserswerth. After the murder of the Archbishop of Cologne, Engelbert of Berg, in 1225, the descendants of Frederick I of Isenberg gained ownership of Mülheim an der Ruhr and thereby of the castle as Lords of Styrum and took up residence. Here they founded the line of Counts of Limburg Styrum, a family that would later obtain important estates in Westphalia and the Lower Rhine. With the partition of the House of Limburg Styrum in 1644, Styrum passed to the line of Limburg-Styrum-Styrum.

Styrum was rebuilt in Baroque style in 1668, and it received its present form after a fire in 1738. In the mediatisation of 1806, Styrum came under control of the Grand Duchy of Berg. The line of Limburg-Styrum-Styrum became extinct in 1809. The last count of the Styrum branch of the family, Ernst Maria Johan (deceased on 23 March 1809) in his will of 29 January 1808 donated Styrum to the sister of his wife: Maria Margaretha von Humbracht, who sold it in 1825.
