Henry III of England

Henry III began the rebuilding of Westminster Abbey in the Gothic style, dedicating it to Edward the Confessor. This project became a major architectural achievement and a symbol of royal piety and power.

Under baronial pressure, Henry III agreed to the Provisions of Oxford, which established a council of barons to oversee royal governance. This reform limited royal power and created a precedent for parliamentary oversight.

Henry III faced the Second Barons' War led by Simon de Montfort. He was captured at the Battle of Lewes, but later restored after the royalist victory at the Battle of Evesham, where de Montfort was killed.

Royalist forces under Prince Edward defeated Simon de Montfort's army at the Battle of Evesham. De Montfort was killed, ending the baronial rebellion and restoring Henry III's full authority.

Henry III issued the Dictum of Kenilworth, a compromise that allowed rebel barons to reclaim their lands by paying fines. This helped reconcile the kingdom after the Second Barons' War.
