Bentheim-Tecklenburg-Rheda
Bentheim-Tecklenburg-Rheda was a historical county located in northwestern North Rhine-Westphalia and southwestern Lower Saxony, Germany. Bentheim-Tecklenburg-Rheda emerged as a partition of Bentheim-Steinfurt in 1606, and it was mediatised to Prussia in 1806.
Today, the still-existing branches of the House of Bentheim are the Princes of Bentheim-Steinfurt with their seat at Steinfurt Castle (also still owners of the ancestral seat, Burg Bentheim), and the Princes of Bentheim-Tecklenburg-Rheda with their seat at Rheda Castle (also still owners of Hohenlimburg Castle).
