This war of succession was, in reality, an incident of the Hundred Years' War, the partisans of Blois and Montfort supporting respectively the kings of France and England.
After the siege of Tournai a truce was arranged on the 25th of September 1340; but the next year the armies of England and France were again at war in Brittany on account of the rival pretensions of Charles of Blois and John of Montfort to the succession of that duchy.
A little later, when Montfort was committed to opposition, Henry foolishly accepted from Innocent IV.
Llewelyn, utterly humbled, now behaved with such prudence that Edward at last sanctioned his marriage with Eleanor de Montfort (although such an alliance must originally have been highly distasteful to the English king), and the ceremony was performed with much pomp in Worcester Cathedral in 1278.
The principal buildings are the church of St Esprit (13th century) now secularized; the Renaissance church of St Gildas; the town-hall (18th century); and, at a short distance from the town, the Carthusian monastery, now a deaf and dumb institute, on the site of the battle of 1364, at which Charles of Blois was defeated by John of Montfort (see Brittany: History).
From the 12th century onwards, its bishops, the first of whom appears to have lived about the 3rd century, began to encroach on the authority of the viscounts; the latter, after the Albigensian war, lost their estates, which passed to Simon de Montfort and then to the crown of France.
By the treaty of Shrewsbury (1265) he was recognized as overlord of Wales; and in return Simon de Montfort was supplied with Welsh troops for his last campaign.
An appeal to the pope they would have laughed to scorn; but the ccsnfidence felt in the probity of the French king was so great that Montfort advised his friends to accede to the proposal.
The deed is mentioned by Dante, who put Guy de Montfort in the seventh circle of hell.
