Kings and Queens of Castile

Jiménez dynasty

Monarch	Epithet	Reign began	Reign ended	Notes
Sancho II	the Strong	27 December 1065	6 October 1072	Oldest son of Ferdinand I of León, who ruled León and Castile, and declared himself Emperor of Spain. Ferdinand did not, however, pass both of his kingdoms on to Sancho but on his death gave instructions to divide the kingdoms among his sons, with Sancho receiving Castile, Alfonso receiving León, and Galicia elevated as a separate kingdom for Garcia. But it did not go well. In 1071, Garcia's kingdom of Galicia was attacked, conquered, and divded between his brothers, and in 1072, Alfonso's kingdom of León was attacked and conquered by Sancho. Sancho did not enjoy his conquests long, however, as in that same year, Sancho was assassinated.
Alfonso VI	the Brave the Valiant	6 October 1072	30 June 1109	Son of Ferdinand I, brother of his predecessor Sancho II. Ferdinand had ruled León and Castile, and on his death attempted to divide his kingdoms between his sons, with Sancho receiving Castile, Alfonso receiving León, and Garcia receiving a newly elevated kingdom of Galicia. Alfonso had first participated with Sancho in dividing Garcia's kingdom between them in 1071, only to lose his own to Sancho in 1072. Happily for Alfonso, Sancho, who was still childless, was almost immediately assassinated, creating opportunities for his brothers to return and attempt to reclaim their father’s kingdoms. As it happened, this only worked out for Alfonso, who captured and imprisoned Garcia, taking all three kingdoms under Alfonso’s control. Alfonso also seems to have adopted the title Emperor of All Spain, sometimes used by his father.
Urraca	the Reckless	30 June 1109	8 March 1126	Daughter of Alfonso VI, and sister to Sancho Alfónsez. Urraca came to the throne on the death of her father, his having been pre-deceased by Sancho in 1108. As Alfonso was king of León as well as Castile, he passed both kingdoms to Urraca. An attempt to create a dynastic unity with neighboring Aragon by a marriage with its king, Alfonso VI of of Aragon, spectacularly failed. Not only was the marriage childless, Alfonso actively waged war on his wife until his death in 1114. Urraca did seem to sometimes use the title Empress of All Spain.

House of Ivrea

The following dynasts are descendants, in the male line, of Urraca's first husband, Raymond of Burgundy.

Alfonso VIII	The Noble	31 August 1158	6 October 1214	Oldest son of Sancho III. Ascending to the throne at the age of 2, the kingdom was divided by a power struggle over control of his regency, which lasted until he was 15.

Alfonso X	The Wise	30 May 1252	4 April 1284	Oldest son of Ferdinand III. He was elected King of Germany in 1257, a title which he held without ever gaining any authority by it until he renounced it in 1275
Sancho IV	The Brave	4 April 1284	25 April 1295	Son of Alfonso X. He ascended over the claims on behalf of the minor son of his deceased older brother Fernando de la Cerda. (The traditions of Proximity of blood and Agnatic seniority, by which younger sons would be preferred over grandsons, were not dead in Castile.) To retain power, Sancho executed thousands of his nephew's supporters during his reign.
Ferdinand IV	The Summoned	25 April 1295	7 September 1312	Oldest son of Sancho IV. He ascended as a minor, amid disputes regarding competing claims to his throne and his regency. His mother retained custody of him (though not the regency) until he was old enough to hold power for himself in 1301.
Alfonso XI	The Just	7 September 1312	26 March 1350	Oldest son of Ferdinand IV. He ascended as an infant, and was under a divided regency of multiple relatives until he took power in 1325. His passion for his mistress led to her having 10 illegitimate children by him, one of whom, the future Henry II, deposed and executed Alfonso’s son and succcessor, Peter.
Peter	The Cruel	26 March 1350	23 March 1369	Oldest legitimate son of Alfonso XI. After a tumultuous reign, an uprising against him begn in 1366, led by his illegitimate half-brother, the future Henry II. Peter was deposed and executed by Henry in 1369.
