Philip IV, called Philip the Fair, was King of France from 1285 to 1314. By virtue of his marriage with Joan I of Navarre, he was also King of Navarre as Philip I from 1284 to 1305, as well as Count of Champagne. Although Philip was known to be handsome, hence the epithet le Bel, his rigid, autocratic, imposing, and inflexible personality gained him other nicknames, such as the Iron King. His fierce opponent Bernard Saisset, bishop of Pamiers, said of him: "He is neither man nor beast. He is a statue."

The Capetian dynasty, also known as the "House of France", is a dynasty of European origin, and a branch of the Robertians and the Karlings. It is among the largest and oldest royal houses in Europe and the world, and consists of Hugh Capet, the founder of the dynasty, and his male-line descendants, who ruled in France without interruption from 987 to 1792, and again from 1814 to 1848. The senior line ruled in France as the House of Capet from the election of Hugh Capet in 987 until the death of Charles IV in 1328. That line was succeeded by cadet branches, the Houses of Valois and then Bourbon, which ruled without interruption until the French Revolution abolished the monarchy in 1792. The Bourbons were restored in 1814 in the aftermath of Napoleon's defeat, but had to vacate the throne again in 1830 in favour of the last Capetian monarch of France, Louis Philippe I, who belonged to the House of Orléans. Cadet branches of the Capetian House of Bourbon are still reigning over Spain and Luxembourg.
