Burials at the Basilica of Saint-Denis

Philip III (1 May 1245 – 5 October 1285), called the Bold (French: le Hardi), was King of France from 1270 until his death in 1285. His father, Louis IX, died in Tunis during the Eighth Crusade. Philip, who was accompanying him, returned to France and was anointed king at Reims in 1271.
Philip inherited numerous territorial lands during his reign, the most notable being the County of Toulouse, which was annexed to the royal domain in 1271. With the Treaty of Orléans, he expanded French influence into the Kingdom of Navarre and following the death of his brother Peter during the Sicilian Vespers, the County of Alençon was returned to the crown lands.
Following the Sicilian Vespers, Philip led the Aragonese Crusade in support of his uncle. Initially successful, Philip, his army racked with sickness, was forced to retreat and died from dysentery in Perpignan in 1285 at the age of 40. He was succeeded by his son Philip IV.

Monsieur d'Orléans (16 April 1607 – 17 November 1611) was the second son and fourth child of Henry IV of France and his consort, Marie de' Medici. Commonly ascribed the names Nicolas or Nicolas Henri and the title Duke of Orléans, he was neither baptised nor invested as such during the course of his short life.
He was betrothed to Marie de Bourbon-Montpensier, heiress to vast lands of the extended House of Bourbon. After his father's death in 1610, he was heir presumptive to his older brother, Louis XIII. Of frail health, he died of seizures brought on by hydrocephalus at the age of four, whereupon his title and betrothal were transferred to Gaston, his younger brother.
