Sicilian Vespers massacre the French
On Easter Monday a drunken French sergeant harassed a Palermitan bride outside the church of Santo Spirito. A riot exploded into a coordinated uprising that killed thousands of Frenchmen across Sicily within weeks. Charles of Anjou lost half his kingdom overnight. The revolt's speed and coordination suggest advance planning, possibly with the backing of Peter III of Aragon and Byzantine gold.
Llywelyn the Last killed at Cilmeri
Caught in the open by English forces during his uprising, the last independent Welsh prince was killed near Builth Wells, reportedly by a lone knight who did not recognize him. His head was sent to Edward I and displayed on a pike in London. Wales lost its native dynasty. The Welsh bards mourned him in verses that became the foundation of a national literature of loss and resistance.
Peter III of Aragon lands in Sicily
Summoned by Sicilian rebels and backed by his wife Constance, Manfred's daughter, Peter III sailed into Trapani and claimed the island. The ensuing War of the Sicilian Vespers would drag on for two decades and splinter Angevin Italy from Aragonese Sicily. The war drew in every major Mediterranean power and demonstrated that popular revolt could shatter even a papally sanctioned kingdom overnight.
Edward I issues Welsh coinage reform
As part of his pacification of Wales, Edward I launched a thorough reform of the English coinage, recalling worn pennies and minting silver groats and farthings for the first time. The new coins circulated from Carnarvon to Bordeaux and underwrote his wars. The reform standardized weights and designs across the realm, creating a uniform currency that facilitated trade and strengthened the crown's fiscal authority.
