The Castilian House of Ivrea, also known as the House of Burgundy, is a cadet branch of the House of Ivrea descended from Raymond of Burgundy. Raymond married Urraca, the eldest legitimate daughter of Alfonso VI of León and Castile of the House of Jiménez. Two years after Raymond's death, Urraca succeeded her father and became queen of Castile and León; Urraca's and Raymond's offspring in the legitimate line ruled the kingdom from 1126 until the death of Peter of Castile in 1369, while their descendants in an illegitimate line, the House of Trastámara, would rule Castile and Aragón into the 16th century.

The Jiménez dynasty, alternatively called the Jimena, the Sancha, the Banu Sancho, the Abarca or the Banu Abarca, was a medieval ruling family which, beginning in the 9th century, eventually grew to control the royal houses of several kingdoms on the Iberian Peninsula during the 11th and 12th centuries, namely the Kingdoms of Navarre, Aragon, Castile, León and Galicia as well as of other territories in the South of France. The family played a major role in the Reconquista, expanding the territory under the direct control of the Christian states as well as subjecting neighboring Muslim taifas to vassalage. Each of the Jiménez royal lines ultimately went extinct in the male line in the 12th or 13th century.
