Castilian House of Ivrea

Origins

Raymond was the fourth son of William I, Count of Burgundy (from the House of Ivrea) and arrived in the Iberian penninsula probably in 1086 with the army of Odo I, Duke of Burgundy, who siege the city Tudela, Navarre. In April 1087 the army abandoned the siege and returned home, but Odo, Raymond and Henry (Raymond's cousin) went west at the court of Alfonso VI king of Castile and León. There, Odo arranged the marriage of king's first daughter Urraca to Raymond on 1087; the couple received the county of Galicia as dowry.^[1] In 1093 Alfonso VI married his second daughter Teresa to Henry and gave them the county of Portugal, which evolved to a kingdom.^[2] In 1107 Raymond died; the next year died Sancho, king's only son and in 1109 the king himself. Urraca succeded him up to her death and then next ruler was her son Alfonso VII, first king of Castile and León from the Castilian House of Ivrea.

Kings of Castile and León

Alfonso VII partitioned the kingdom to his sons: Sancho III received Castile & Toledo and Ferdinand received León & Galicia. The kingdom remained divided by their sons Alfonso VIII of Castile and Alfonso IX of León recpectively, but in 1197 the latter married the daughter of the former, so their son Ferdinand III of Castlile and León reunited the two kindoms. Ferdinand III married Elisabeth of Swabia, the daughter of Irene Angelina, and heir son was Alfonso X.

Alfonso X's eldest son Ferdinand died in 1275 leaving two sons, but king's second son Sancho claimed to be the new heir. The king prefered Ferdinand's sons, but the nobility supported Sancho and a civil war began. The descedents of Ferdinand form the House of la Cerda. Alfonso X died in 1284 and finally succeeded him his second son, as Sancho IV. The grandson of Sancho IV, i.e. Alfonso XI, had legitimate son Peter of Castile and some illegitimate sons: Henry, Fadrique, etc. Since Peter had no legitimate sons, Henry attacked Peter with a host of soldiers of fortune in 1366. The Castilian Civil War followed: Peter was besieged at the fortress of Montiel. During the negotiations, Peter enter the tent of Henry's envoy, where Henry, which was hidden there, attecked Peter and killed him. Henry become the new king as Henry II and was the founder of the House of Trastámara. His brother Fadrique become the founder of the House of Enríquez.
