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 divided 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. He died without children.
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, as her brother had died 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 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.

Although his father was king of Castile, León, and Galicia, Sancho only inherited Castile, with León and Galicia going to his younger brother Ferdinand. (Castile , León, and Galicia would be later re-united in 1230 under Ferdinand III.)
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.

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.

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 successor, 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.

In 1366, Peter's conduct led to an uprising by his illegitimate half-brother Henry with support from France and Aragon. After three years, Henry triumphed in 1369, and personally executed Peter.

Isabella I	The Catholic	11 December 1474	26 November 1504	Half-sister of Henry IV. Her succession was disputed by partisans of Henry's (allegedly illegitimate) daughter Joanna, resulting in the War of the Castilian Succession, which lasted until 1479, with the resolution in Isabella's favor. Isabella's husband Ferdinand, ruled with her as co-monarch of Castile, while on his ascension to the Crown of Aragon, she ruled as co-monarch of Aragon.

Philip I	The Handsome	26 November 1504	25 September 1506	jure uxoris king ruling on behalf of his wife, Joanna I. As the oldest son of Mary of Burgundy, Philip also inherited the titles of Lord of the Netherlands and Duke of Burgundy on his mother's death in 1482.
Charles I	The Emperor	13 March 1516	16 January 1556	Son of Philip I and Joanna I. In 1516 he was made co-monarch with his mother, becoming sole monarch of Castile on her death in 1555. Charles also inherited the titles Lord of the Netherlands and Duke of Burgundy on his father's death in 1506, King of Aragon on the death of his maternal grandfather Ferdinand II in 1516, and Archduke of Austria on the death of his paternal grandfather Maximilian I in 1519. In 1519, he was also elected to the non-hereditary position of Holy Roman Emperor. Governing such a vast and disparate set of realms proved exceedingly difficult. In Castile, his rule was challenged in 1520-1522 by the broadly-based Revolt of the Comuneros, and in neighboring Aragon in 1519-23 by the Revolt of the Brotherhoods. Both were overcome by a combination of force and compromise. After a long reign Charles abdicated in 1556, dividing his lands between his son Philip II (who inherited the lands of the Crown of Castile (including the Americas), the Crown of Aragon, his Italian territories, and the Netherlands) and his younger brother Ferdinand, who inherited the rest. Charles died in 1564.
Philip II	The Prudent	16 January 1556	13 September 1598	Son of Charles I. Through his father's abdication, he inherited not only the lands of the Crown of Castile (including the American colonies) but also those from the Crown of Aragon, (including the kingdoms of Naples, Sardinia, and Sicily), the Duchy of Milan, as well as the titles of Lord of the Netherlands and Duke of Burgundy. His rule in the Netherlands was challenged by a powerful rebellion , leading to the establishment of the Dutch Republic in 1579 and the Eighty Years' War, which expanded to include multiple other wars, ending only with Spanish recognition of Dutch independence in 1648. In 1580, during a succession crisis in the Kingdom of Portugal when there was no obvious heir to the throne, Philip (a candidate in his own right) invaded and was made king that same year. Through his marriage to Mary I of England in 1554, Philip was nominal King of England until her death, but he never exercised any power there.
Philip III	The Pious	13 September 1598	31 March 1621	Son of Philip II. Philip III became heir to the crown after the death of his older brother, Carlos, who died insane and in captivity in 1568.
Philip IV	The Great	31 March 1621	17 September 1665	Oldest son of Philip III. A revolt against Philip in Portugal led to Portugal's regaining its independence in the Portuguese Restoration War, from 1640-1668.
Charles II	The Bewitched	17 September 1665	1 November 1700	Oldest surviving son of Philip IV. (Two older brothers died young.) His reign was marked by his life-long ill-health and he died childless, leading to the War of the Spanish Succession, from 1701 to 1714.
