Kings and Queens of Castile

Jiménez dynasty

Monarch	Image	Epithet	Reign began	Reign ended	Notes
Sancho II		the Strong	27 December 1065	6 October 1072	Eldest 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 I of Aragon, spectacularly failed. Not only was the marriage childless, Alfonso actively waged war on his wife until their divorce in 1114. Urraca did seem to sometimes use the title Empress of All Spain.

House of Ivrea / Burgundy

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

Henry II, the founder of the Trastámara dynasty was installed after victory in the Castilian Civil War.

Isabella I		The Catholic	11 December 1474	26 November 1504	Half-sister of Henry IV.

Philip I		The Handsome	26 November 1504	25 September 1506	jure uxoris king ruling on behalf of his wife, Joanna I. As the Eldest 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.

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 and his younger brother Ferdinand, who inherited the rest. Charles died in 1564.
Philip II	100px	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 but also those from the Crown of Aragon,, 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 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	100px	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.

Charles II	100px	The Bewitched	17 September 1665	1 November 1700	Eldest surviving son of Philip IV. 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.
