🛡️ A War Under Religious Language

The campaign targeted Aragon, but it was mobilised through a spiritual and papal justification. In reality, this was a war of dynasties and Mediterranean control, in which logistics and money weighed as much as arms.

🦠 A Reign’s End by Attrition

The expedition aimed at Catalonia: siege of Girona (summer 1285), naval and land battles, then a harassed retreat. Disease and campaign fatigue played a central role: the army was struck by dysentery, and the retreat turned into a disaster (Formigues, col de Panissars).

Philip III died at Perpignan on 5 October 1285. As the king died far from Paris, his body underwent funeral treatment designed to limit decomposition and allow transport. The sovereign’s memory was deployed across several sites: the remains were divided (heart, entrails, bones), following a practice of multiple burials that multiplied ceremonies and commemorative spaces.

The expedition ended without lasting success, but the succession was secured: Philip IV inherited an enlarged kingdom and a solid apparatus of state.

🧠 Key Points to Remember

• The “Aragonese Crusade” reveals a more Mediterranean, more conflict-ridden political world.
• Capetian dynastic continuity remains a major asset: power was transmitted without crisis.
