The Principality of Salm
Around 1190, Count Henri II of Salm built a castle which, after several modifications, was already in ruins by the 16th century. At the same time, members of this lineage became sole masters of the territory in 1571, but since it remained undivided, sovereignty was shared between the two branches of the family.
La Broque thus became a divided village, with one half belonging to the Dukes of Lorraine who retained it until 1751. At that date, it also came under the authority of the Prince of Salm-Salm.
When the Principality of Salm was annexed by France in 1793, the commune joined the Vosges department before being detached by the Treaty of Frankfurt in 1871. Sites to discover include the Kupferschmitt farm, the Salm oak, the Anabaptist cemetery, and the remains of Salm Castle.
