The itinerary of Johannes de Plano Carpini (itinerary in blue)

Anglo-Welsh War

  • Earlier this year: In the English-Welsh war defeat British troops one led by Dafydd ap Llywelyn of Gwynedd united Welsh forces at Montgomery Castle .
  • March 28th : The Welsh conquer Mold Castle .
  • June: King Heinrich III. of England calls his feudal army to Chester , from where in August he sets out on another campaign to Wales. English troops advance along the North Wales coast to the Conwy estuary , which they reach on August 26th . There the advance stops and the English begin to rebuild Deganwy Castle .
  • For the next two months the English army encamped on the Conwy. Welsh raids at night and supply shortages demoralize soldiers, leading to the sacking of Aberconwy Abbey and other rioting. The Welsh responded with further robberies and executions of prisoners. An English force arriving from Ireland sacked the island of Anglesey , but at the end of October the main English army withdrew to Chester in view of the approaching winter. The King appoints John Gray as the new Justiciar of Chester and imposes a trade blockade on Wales.

Iberian Peninsula

  • March: Pope Innocent IV accuses King Sancho II of Portugal of the worst offenses in the Bull Inter alia desiderabilia . On July 24th, in Grandi non immerito , he declares him an “unfit ruler” ( rex inutilis ) and his brother Alfons III. to the "administrator and defender" of the kingdom. Sancho II, however, is not prepared to accept this dismissal without a fight; civil war breaks out in Portugal .
