Europe

• Vikings plunder London and Canterbury.
• Charles the Bald, Louis the German and Lothar meet in Meersen.
• Garcia Iñiguez succeeds his father Iñigo Arista as king of Navarra.
• August 22 – Battle of Jengland. Erispoe, king of Brittany and son of Nominoe, defeats the Franc king Charles the Bald in Jengland-Beslé near Grand-Fougeray in Brittany. This is considered as the birth of the Breton state.
• September – Treaty of Angers. Charles the Bald acknowledges Erispoë as king of Brittany. He lets him have the County of Nantes, the County of Rennes and the County of Retz which become part of the Breton nation. The King of Brittany takes the oath to the King of France (but not an hommage lige which would be an allegiance). To mark the sovereignty of the Breton state, the Dukes of Brittany are since then crowned as "Duke, king in their lands".^[1]
