In 1093 Urraca's mother died and Alfonso's Moorish concubine Zaida of Seville gave birth to a son, Sancho Alfónsez. The birth of her illegitimate brother jeopardized Urraca's position as their father's sole heir. The power base of Raymond and Urraca weakened even more when Alfonso granted the "Land of Portugal" to his illegitimate daughter Theresa and her husband Henry of Burgundy around 1094. As a woman, Urraca was under the tutelage of her husband. Raymond was mentioned at the first place in 
Title: Urraca of León
Content:  Urraca was born to King Alfonso VI of León and Castile and Constance of Burgundy. Constance—Alfonso's second wife—was closely related to the French royal family and the influential Burgundian abbot Hugh of Cluny was her maternal uncle. As Constance was also related to her husband's first wife, Agnes of Aquitaine, Pope Gregory VII only confirmed their marriage after Alfonso agreed to replace the traditional Mozarabic liturgy in his realms with the Roman Rite. The place and date of Urraca's birth are unknown, but she was born likely in Sahagún or León around 1080, probably in 1081. Although she was her parents' sole child, her childhood is poorly documented. She would mention one Presbyter Pedro and a certain Domingo Falcóniz, two otherwise unknown clergymen, as her tutors in her royal diplomas. Her relationship with her paternal aunt Elvira was obviously close, as it is demonstrated by Elvira's appointment as guardian of Urraca's daughter Sancha Raimúndez. A late source, Rodrigo Jiménez de Rada, claims that the powerful aristocrat Pedro Ansúrez and his wife Elo Alfónsez raised Urraca in their household, but no contemporaneous document confirms this report.
