The presence of Henry's extended family in England proved controversial. Concerns were raised by contemporary chroniclers – especially in works of Roger de Wendover and Matthew Paris – about the number of foreigners in England and historian Martin Aurell notes the xenophobic overtones of their commentary. The term "Poitevins" became loosely applied to this grouping, although many came from Anjou and other parts of France, and by the 1250s there was a fierce rivalry between the relatively well established Savoyards and the newly arrived Poitevins. The Lusignans began to break the law with impunity, pursuing personal grievances against other barons and the Savoyards, and Henry took little or no action to restrain them. By 1258, the general dislike of the Poitevins had turned into hatred, with Simon de Montfort one of their strongest critics.
