Lordship of Léon


The Lordship of Léon, later Principality of Léon was a former Breton fief located in the Léon province, in north-western Brittany, which corresponds roughly to the French département Finistère. This lordship was created after the Viscounty of Léon was divided into a viscounty and the lordship at the end of the 12th century. The lordship of Léon was a large fief made of about sixty parishes and . The estates of the lordship are located around the valley of the Élorn river, the town of Landerneau and the castle of La Roche-Maurice. The lordship was initially held by the junior branch of the Viscounts of Léon, which was founded by Harvey I. After Harvey VIII died without issue, the fief was inherited by the Viscounts of Rohan. In the middle of the 16th century the fief became known as "Pincipality of Léon". Landerneau, Landivisiau, Daoulas, Coat-Méal, Penzé and La Roche-Maurice were the seats of the jurisdictions of this huge Breton lordship.

History

In the 12th century, the Viscounts of Léon rebelled against Henry II of England in order to escape Plantagenet's domination in the Duchy of Brittany. In 1179, after the death of Guihomar IV, who had submitted to the Ducal power not long before, Henry II of England confiscated the Léon estates. Following the confiscation of Morlaix by Duke Geoffrey Plantagenet, Guihomar IV's two sons Guihomar V et Harvey recovered their inheritance. Guihomar V got the castellanies of Lesneven, Brest, Saint-Renan and Le Conquet as well as the title of Viscount. Harvey got the estates of Landerneau and Daoudour, as well as the lordship of Coat-Méal. Being a juveigneur, i.e. a younger son endowed with an estate, Hervé had to content himself with the title of Lord of Léon and founded the junior branch of the House of Léon, which managed to keep his fief of La Roche-Maurice for 8 generations.

House of Léon

During the War of the Breton Succession which started in 1341, the Lords of Léon supported Charles of Blois partly because of their links with the House of Avaugour. Harvey VII of Léon was captured by the English in 1342 and spent two years imprisoned in the Tower of London. He died in 1344 soon after he was released. The fief of La Roche-Maurice was inherited by his son Harvey VIII of Léon, then aged 3. A note in the Lords of Léon's Bible indicates that Harvey VIII was born in La Roche-Maurice in 1341. During the War of the Breton Succession, the situation became confused. The last Lord of Léon died without issue in 1363. The fief was inherited by John I, Viscount of Rohan through his marriage with Joan of Léon, Harvey VIII's sister.
In 1363, Harvey VIII died without issue: the Lordship of Léon was inherited by his sister Joan, wife of John I of Rohan. The Lordship became part of the estates held by the Rohans. From this time up to 1517, the Rohans' eldest sons would live in the castle of La Roche-Maurice and style themselves Lord of Léon before becoming Viscounts of Rohan.

House of Rohan

The Viscounts of Rohan, later Dukes of Rohan styled themselves Prince of Léon in the early 16th century and the Lordship became Principality of Léon.
The heir apparent is the present Duke Josselin de Rohan's son, Alain Louis Marc de Rohan-Chabot
