Louis had three younger brothers: Philip IV the Fair,[2] Robert and Charles.[3] His mother died in Calabria following a riding accident during her pregnancy with her fifth child, in 1270.[4] At his death at the age of 12, his younger brother Philip, succeeded him as heir apparent.[5]
Circumstances of his death
Following his death, Pierre de la Broce, Philip's chamberlain,[6] accused Mary of Brabant, Philip's second wife, of poisoning Louis.[1] By 1277, suspicion had fallen on Pierre de la Broce, who was then tried for treachery, and hanged at Montfaucon.[1]
