John's personal life greatly affected his reign. Contemporary chroniclers state that John was sinfully lustful and lacking in piety. It was common for kings and nobles of the period to keep mistresses, but chroniclers complained that John's mistresses were married noblewomen, which was considered unacceptable. John had at least five children with mistresses during his first marriage to Isabelle of Gloucester, and two of those mistresses are known to have been noblewomen. John's behaviour after his second marriage to Isabella of Angoulême is less clear, however. None of John's known illegitimate children were born after he remarried, and there is no actual documentary proof of adultery after that point, although John certainly had female friends amongst the court throughout the period. The specific accusations made against John during the baronial revolts are now generally considered to have been invented for the purposes of justifying the revolt; nonetheless, most of John's contemporaries seem to have held a poor opinion of his sexual behaviour.[nb 14]
