“In the year 1276, Alfonso the Wise had defeated Yussuf, the Emperor of Marocco, and made peace with him with the assistance of Guzman: a tournament was held in Seville in celebration of it, and King Alfonso having asked who had most distinguished himself, was told D. Alonzo Perez. He asked which of them, and D. Juan Ramirez de Guzman replied: ‘Alonzo Perez de Guzman, my brother of profit.’ This answer seemed ill to all, and especially to Guzman, who saw that a slur was cast upon the illegitimacy of his birth, for at that time they named children of profit (_gananciu_), those who were born of unmarried women, and his mother had not been married. Guzman, irritated at being thus spoken of before the king and the court, then said: ‘You speak truth, I am a brother of profit, but you are and will be one of loss; and were it not for the respect due to the presence in which we stand, I would teach you the manner in which you should treat me; but you are not to blame for it, but rather he who has brought you up and taught you so ill.’ The king, against whom this complaint appeared to be directed, then said: ‘Your brother does not speak ill, for so it is the custom in Castile to name those who are not children of women married to their husbands.’ ‘So also,’ he replied, ‘is it the custom of the nobles of Castile, when they are not well treated by their sovereigns, to go abroad to seek those who will treat them well; I will do likewise; and I swear not to return until with truth they may call me a man of profit. Grant me, therefore, the term which the privilege of the nobles of Castile gives, that I may go out of the kingdom, for from this day I disnaturalise myself, and take leave of being your vassal.’ The king attempted to dissuade him, but his efforts being in vain, he had to grant him the term which he asked for; during which Guzman sold all that he had inherited from his father or acquired in the war, and went out from Castile, accompanied by thirty of his friends and servants.”—Quintana, _Vidas de Españoles Celebres_.
