The Kingdom of Brittany (Breton: Rouantelezh Breizh) was a short-lived vassal-state of the Frankish Empire that emerged during the Norse invasions. Its history begins in 851 with Erispoe's claim to kingship. In 856, Erispoe was murdered and succeeded by his cousin Salomon.

The kingdom fell into a period of turmoil caused by Norse invasions and a succession dispute between Salomon's murderers: Gurvand and Pascweten. Pascweten's brother, Alan, called the Great, was the third and last to be recognized as King of Brittany.^[1] After his death, Brittany fell under Norse occupation.

When Alan Twistedbeard, Alan the Great's grandson, reconquered Brittany in 939, Brittany became a sovereign duchy until its union with France in 1532.
