The emergence of the Breton princedom predated that of the Duchy of Burgundy. As successor to his murdered cousin Erispoë in 857, Salomon had at first claimed the title 'prince by the grace of God of all Brittany and of a large part of Gaul.' As a result of clan feuding, Salomon was assassinated in 874. His relatives Pascwethen and Gurwant arranged an uneasy partition of the peninsula into northern and southern halves. Both men were replaced by another pair of rulers, Alan, count of Vannes, Pascwethen's brother, and Judicaël, Gurwant's son. 121
