Duchy of Mercœur
The reign of Mercœur was elevated to the Duchy of Mercœur in 1569. It was in the Auvergne or in the later Haute-Loire department . The capital of the Seigneurie and the Duchy was the place Mercœur .
Mercœur was in the hands of the same family from the end of the 9th century until 1321, which was inherited by the Dauphins of Auvergne . Their heirs, in turn, were the Dukes of Bourbon , who gave Mercœur to the Counts of Montpensier, their younger line. Gilbert de Bourbon-Montpensier gave the rule to his daughter Renée as a dowry, whereby Mercœur went to the House of Châtenois . Nicholas of Lorraine , Lord of Mercœur, was made Duke of Mercœur in 1569. Via his granddaughter Françoise , the duchy came back to the Bourbons.
When Louis II. Joseph, duc de Vendôme et de Mercœur , died in 1712, the king refused to succeed his brother Philippe , as he was not allowed to have any property as the Grand Prior of the Order of Malta , and took the duchy.
