Lordship of Styrum
Herrschaft Styrum
unknown - 1806

To Mülheim ?
To Limburg 1289
Mediatised to Berg 1806

The Lordship of Styrum was a small territory located around the Castle of Styrum in North Rhine-Westphalia, Germany on the Ruhr River. The Lordship was first mentioned in 1067 as belonging to the Lords of Mülheim. It passed to the Counts of Limburg in 1289. Despite the small size of the territory and that it was entirely surrounded by the Duchy of Berg, the immediacy of the Lordship was never disputed and the Lords held the right to appeal directly to the Holy Roman Emperor in times of need.

Styrum During and After the Holy Roman EmpireEdit

The Counts of Altena and Isenberg fled to Styrum after they were dispossessed of their lands in 1226 after the murder of Engelbert of Berg, the Archbishop of Cologne. The Counts of Limburg were guaranteed the Lordship, and it remained in the family until the end of the Holy Roman Empire. It passed to the line of Limburg-Styrum in 1271, and to the line of Limburg-Styrum-Styrum in 1644.

In the mediatisation of 1806, Styrum was annexed to the Grand Duchy of Berg. The line of Limburg-Styrum-Styrum became extinct in 1808. The Congress of Vienna awarded Styrum to Prussia in 1814 following the final defeat of Napoleon Bonaparte.
