County of Mayenne

The County of Mayenne was the regional claim around the city of Mayenne, ruled by the Count of Mayenne. They were usually under the jurisdiction of the duke of Alençon, the title having been created at the start of the Hundred Years' War, in 1337 CE. At this time, the Duchy of Alençon was a vassal of the Kingdom of England, and was at war with the Kingdom of France. Mayenne played a small part in the war, the Battle of Évron (which was in the jurisdiction of the County) taking place in 1346 CE. The war was on-and-off, and eventually Mayenne fell into the jurisdiction of the Kingdom of Brittany at the Peace of Caen in 1404 CE.
