Urraca (April 1079 – 8 March 1126) was Queen of León, Castile, and Galicia, and claimed the imperial title as suo jure Empress of All the Spains from 1109 until her death in childbirth, as well as Empress of All Galicia.
Born in Burgos, Urraca was the eldest and only surviving child of Alfonso VI of León with his second wife Constance of Burgundy; for this, she was heiress presumptive of the Kingdoms of Castile and León until 1107, when her father recognized his illegitimate son Sancho as his heir.
Urraca’s place in the line of succession made her the focus of dynastic politics, and she became a child bride at age eight (1087) to Raymond of Burgundy, a mercenary adventurer. Author Bernard F. Reilly suggests that, rather than a betrothal, the eight-year-old Urraca was fully wedded to Raymond of Burgundy, as he almost immediately appears in protocol documents as Alfonso VI's son-in-law, a distinction that would not have been made without the marriage. Reilly doubts that the marriage was consummated until Urraca was 13, as she was placed under the protective guardianship of a trusted magnate. Her pregnancy and stillbirth at age 14 suggest that the marriage was indeed consummated when she was 13 or 14 years old.
