Peter I, Duke of Bourbon

From Wikipedia, the free encyclopedia

Peter I of Bourbon (1311 – September 19, 1356, Poitiers) was the second Duke of Bourbon, from 1342 to his death.

Peter was son of Louis I of Bourbon, whom he also succeeded as Grand Chamberlain of France, and Mary of Hainaut.

Duke Peter is reported to have been mentally somewhat instable, a trait of nervous breakdowns presumably hereditary that showed clearly for example in his daughter Jeanne de Bourbon, the queen, and in her son, king Charles VI of France, as well as in Peter's only surviving son, Duke Louis II.

On 25 January 1326 he married Isabella of Valois, daughter of Charles, Count of Valois and his third wife Mahaut of Chatillon. Peter and Isabella had only one son, Louis, and seven daughters. These were:

• Jeanne (1338–1378), married King Charles V of France
• Blanche (1339–1361, Medina-Sidonia), married King Pedro of Castile in 1353 in Valladolid, poisoned by her husband
• Bonne (1341 – January 19, 1402, Château de Mâcon), married Amadeus VI, Count of Savoy in 1355 in Paris
• Catherine (1342–1427, Paris), married John VI, Count of Harcourt
• Margaret (1344–1416), married Arnaud Amanieu, Viscount of Tartas
• Isabelle (b. 1345)
• Mary (1347–1401, Poissy), Prioress of Poissy

Peter died in the Battle of Poitiers.
