Treaty of Lunéville
In 1742, Salm-Kyrburg was raised to a principality; it shared its vote in the Reichstag with Salm-Salm. Salm-Kyrburg was annexed by France in 1798; this was recognized by the Holy Roman Empire in the Treaty of Lunéville of 1801. As a compensation, the princes were granted new territories formerly belonging to the Bishops of Münster in 1802, which formed the newly founded Principality of Salm.
