Duchy of Penthièvre
The county Penthièvre was in the northeast of Brittany and largely corresponded to the present-day Côtes-d'Armor department ; it was created in 1034 when Duke Alain III. sought a rule for his brother Odo, and subsequently served as the paragium of the younger sons of the dukes of Brittany.
Due to the economic power of the area, the importance of the County of Penthièvre soon grew so strongly that the counts became competition for the dukes of Brittany - which prompted Duke Peter around 1216 to take advantage of the incumbent's minority and to take back most of his property .
A hundred years later, in 1317, the county of Penthièvre was again given to a younger family member, but then quickly fell into the hands of the Counts of Blois after Johanna, Countess of Penthièvre, daughter of Guys of Brittany, gave it to Count Karl von Blois in 1337 as a marriage property would have. The Counts of Blois used Penthièvre in the War of the Breton Succession as their bastion in Brittany; after their defeat in this dispute (1364), the Blois-Penthièvre family sold the Breton property to King Louis XI. († 1483), but not the title itself, which was still in use in the family until 1727, since the 16th century as "Duke of Penthièvre".
Penthièvre also came to the houses of Brosse and Luxembourg by marriage and was taken over by King Charles IX. Elevated to a duchy in 1569, which subsequently fell to the crown.
After the Dukes of Penthièvre died out, King Louis XIV restored the duchy in 1697 and gave it to one of his sons from Madame de Montespan , the Count of Toulouse, Louis Alexandre , who died in 1737. His son was Louis Jean Marie de Bourbon, Duke of Penthièvre , born on November 16, 1725 in Rambouillet .
With the marriage of his daughter Marie Louise Adélaide de Bourbon to the Duke of Orléans, known as the “Citizen Egalité”, the wealth of the Penthièvre family came to the Orléans family. In this received the title of Duke of Penthièvre the son of the Prince of Joinville , Prince Pierre Philippe Jean Marie of Orléans , born on November 4, 1845 in Saint-Cloud .
