Philip, Count of Longueville

Philip of Navarre, Count of Longueville (1336–1363) was a younger brother and supporter of Charles II of Navarre, a claimant to the French throne. The son of Philip III of Navarre and Joan II of Navarre, he married Yolande of Flanders in 1353. She was the daughter of Robert of Flanders and Jeanne of Brittany (from the House of Capet) and the widow of Henry IV of Bar. The marriage was childless, though by his mistress Jeannette d'Aisy Philip had two illegitimate children - Lancelot (who was granted Longueville as a gift in 1371 by his uncle Charles II of Navarre so long as he served in the company of the duc de Bretagne) and Robine (granted Longueville by her uncle Louis of Navarre in 1367). Philip and his brother Charles fought against John II of France in 1353.

Christmas 1353 he followed his brother Charles to Paris where they intended to pick a quarrel. On arrival they exchanged insults with Charles de la Cerda (also known as Charles of Spain), the Constable of France, in the king’s presence, Philip even going so far a drawing his dagger.

Two weeks later Charles de la Cerda was travelling unescorted through Normandy when on 7 January 1354 Philip with a band of Norman and Navarrese followers including John, Count of Harcourt, the Bascon de Mareuil and Rabigot Dury, came to the village of l'Aigle and inn where Charles was spending the night. After surrounding the inn Philip stormed into Charles bedroom saying “Charles of Spain, I am Philip, son of a King, whom you have foully slandered.” According to one account Charles begged for his life and promised to leave France forever, but the Bascon de Mareuil and Rabigot Dury fell upon him with four other troopers and stabbed him to death. In all eighty wounds was found on the body of Charles of Spain. The murder of Charles of Spain brought about a break in relations between the King of Navarre and the King of France and occasioned the first of Charles of Navarre's many rapprochements with the English. This time it was not to last long. Already in February Philips brother was, formally at least, reconcile to King John II. In the Treaty of Mantes concluded 22 February Charles of Navarre gained considerable territories in Lower Normandy as well as promises of pardons for Charles, his brothers and confederates for the murder of Charles of Spain.
