Louis of France (1263 or 1264 – Château de Vincennes, before May 1276), was a French prince. He was the eldest son of King Philip III of France and his first wife, Isabella of Aragon (1247-1271). He was the heir apparent to the French throne from August 25, 1270 (at the death of his grandfather Louis IX of France), until his own premature death, at the age of 12-13.
His mother died in Calabria following a riding accident during her pregnancy with her fifth child. Louis was then 7–8 years old.
At his premature death at the age of 12 or 13, his younger brother Philip, the future Philip IV of France, succeeded him as heir apparent.
Infamous suspicions, insidiously ascribed to the royal favorite Pierre de la Broce (c. 1230 - hanged at Gallows of Montfaucon, 1278), hinted that the young Louis was poisoned by his stepmother, Mary of Brabant (1254-1321), the second wife of Philip III of France, whose purpose was to eliminate successively the sons of Isabella.
Pierre de la Brosse was arrested, then hanged.
