Duc de Boisroyeux

Duc de Boisroyeux is a title in the Aleurian nobility. Unlike the other Ducs of Aleuria this title is mostly customary, being given to the heir apparent to the reigning monarch of Aleuria. For this reason, in Province Boisroyeux the roles typically performed by an Aleurian Duc are instead performed by the Marchis de Boisroyeux.
== History of the title ==
Following the execution of the rebel Duc Bonné Boiseignuer, the title was stripped from his household and given to the royal heir apparent at the time. After the king realised his heir was incapable of handling the duties of Ducdom, he appointed a Marchis to look after the province. This arrangement has persisted into modernity.
