Early life William was the son of William IX by his second wife Philippa of Toulouse. He was born in Toulouse during the brief period when his parents ruled the capital. His birth is recorded in the Chronicle of Saint-Maixent for the year 1099: Willelmo comiti natus est filius, equivoce Guillelmus vocatus ('a son was born to Count William, named William like himself'). Later that same year, much to Philippa's ire, Duke William IX mortgaged Toulouse to Philippa's cousin, Bertrand of Toulouse, and then left on crusade. Coin of William X 0,890g. William and his mother, Philippa, were left in Poitiers. W
