John married three times but died with no male heirs. He married firstly, in 1298, Isabelle, sister of Philip IV of France; secondly, in 1310, Isabella, daughter of Sancho IV of Castile; and thirdly, in 1329, Joan, only child of Edward of Savoy. His death triggered the Breton War of Succession (1341-1364), which opposed the House of Blois and the rights of his niece Joanna of Dreux, to the House of Montfort, a cadet branch of the ducal family of Brittany, led by John of Montfort and his homonymous son. This civil war was an incident of the Hundred Years War.
