In the spring of 1220, Isabella married Hugh X of Lusignan, "le Brun", Seigneur de Luisignan, Count of La Marche, the son of her former fiancé, Hugh IX, to whom she had been betrothed before her marriage to King John. It had been previously arranged that her eldest daughter Joan should marry Hugh, and the little girl was being brought up at the Lusignan court in preparation for her marriage. Hugh, however, upon seeing Isabella, whose beauty had not diminished, preferred the girl's mother. Joan was provided with another husband, King Alexander II of Scotland, whom she wed in 1221.
