In the reign of Ordoño I of Asturias (850–866), the kingdom began to be known as that of León. In 910, an independent Kingdom of León was founded when the king of Asturias divided his territory amongst his three sons.
Below follows a list of monarchs of León. It is, in part, a continuation of the list of Asturian monarchs.
The Kingdom of León was an independent kingdom situated in the northwest region of the Iberian Peninsula. It was founded in 910 when the Christian princes of Asturias along the northern coast of the peninsula shifted their capital from Oviedo to the city of León. The kings of León fought civil wars, wars against neighbouring kingdoms and campaigns by both the Moors and the Vikings, all in order to protect their kingdom's changing fortunes.
García is the first of the kings described by the charters as reigning in León. It is generally assumed that the old Asturian kingdom was divided among the three sons of Alfonso III of Asturias: García (León), Ordoño (Galicia) and Fruela (Asturias), as all three participated in deposing their father. When García died in 914, León went to Ordoño, who now ruled both León and Galicia as Ordoño II. At Ordoño's death in 924, the throne went to his brother Fruela II (924–925), who died of leprosy a year later. Fruela's death in 925 was followed by a civil war, after which Alfonso, the eldest son of Ordoño II, emerged as the new king Alfonso IV, ruling from 925 to 932. After a further power struggle, Ramiro, the younger brother of Alfonso IV, became king in 932, having captured his brother Alfonso, as well as the three sons of Fruela II – Alfonso, Ordoño and Ramiro. Alfonso IV may have died soon after, but he left two infant sons, called Ordoño and Fruela. When Ramiro died in 951, he left two sons by two different wives. When the elder son Ordoño III, who ruled from 951 to 956, suddenly died aged little more than thirty, he was succeeded by his younger half-brother Sancho I "The Fat" (956–966), as Ordoño had failed to produce a legitimate heir.
The Crown of Castile was a medieval polity in the Iberian Peninsula that formed in 1230 as a result of the third and definitive union of the crowns and, some decades later, the parliaments of the kingdoms of Castile and León upon the accession of the then Castilian king, Ferdinand III, to the vacant Leonese throne. It continued to exist as a separate entity after the personal union in 1469 of the crowns of Castile and Aragon with the marriage of the Catholic Monarchs up to the promulgation of the Nueva Planta decrees by Philip V in 1716.
In 1492, the voyage of Christopher Columbus and the discovery of the Americas were major events in the history of Castile. The West Indies, Islands and Mainland of the Ocean Sea were also a part of the Crown of Castile when transformed from lordships to kingdoms of the heirs of Castile in 1506, with the Treaty of Villafáfila, and upon the death of Ferdinand the Catholic. The discovery of the Pacific Ocean, the conquest of the Aztec Empire, the conquest of the Inca Empire, the Spanish conquest of New Granada as well as the conquest of the Philippines all helped shape the Crown of Castile into a global empire in the 16th Century.
Isabella I (Spanish: Isabel I; 22 April 1451 – 26 November 1504), also called Isabella the Catholic (Spanish: Isabel la Católica), was Queen of Castile and León from 1474 until her death in 1504. She was also Queen of Aragon from 1479 until her death as the wife of King Ferdinand II. Reigning together over a dynastically unified Spain, Isabella and Ferdinand are known as the Catholic Monarchs. Her reign marked the end of Reconquista and also the start of Spanish Empire and dominance of Spain over European politics for the next century.
Isabella's marriage to Ferdinand of Aragon in 1469 created the basis of the de facto unification of Spain. With Ferdinand's help, she won the War of the Castilian Succession, securing her position as Queen of Castille. Isabella reorganized the governmental system, brought the crime rate down, and unburdened the kingdom of the debt which her half-brother King Henry IV had left behind. Her reforms and those she made with her husband had an influence that extended well beyond the borders of their united kingdoms.
John I (Spanish: Juan I; 24 August 1358 – 9 October 1390) was King of Castile and León from 1379 until 1390. He was the son of Henry II and of his wife Juana Manuel of Castile. John ascended to the throne in 1379 and in 1383, he married Beatrice, the daughter of King Ferdinand I of Portugal. When Ferdinand died that same year, John, aiming to enforce his claim on the Portuguese crown through his wife, brought the country into the 1383–1385 Crisis. His forces faced resistance from Portuguese factions supporting John of Aviz. The conflict culminated in the Battle of Aljubarrota in 1385, where John suffered a defeat, ensuring Portugal's independence.
To secure Castile, he married his son Henry to the daughter of John of Gaunt, linking the Trastámara and Plantagenet dynasties. He died in 1390 when he fell from his horse during a fantasia performance. His death led to minority rule under his son, Henry III.
García I (c. 871 – 914) was the King of León from 910 until his death and eldest of three succeeding sons of Alfonso III of Asturias by his wife Jimena.
García took part in the government alongside his father until 909. In that year a conspiracy, in which García was implicated, was uncovered. Alfonso renounced the throne and divided the realm among his three sons. León went to García, Galicia to Ordoño, and Asturias to Fruela. Asturian primacy was nevertheless recognised.
This is a list of the rulers of the Kingdom of Asturias, a kingdom in the Iberian Peninsula during the Early Middle Ages. It originated as a refuge for Visigothic nobles following the conquest of Iberia by the Umayyad Caliphate. Following the forced abdication of Alfonso III by his sons in 910, the kingdom was split into three: Asturias, León, and Galicia. All three were reunited in 924 under the Kingdom of León.
For later kings, see the list of Leonese monarchs and the list of Galician monarchs. From 1388, the title Prince of Asturias has been used for the heirs to the Castillian and Spanish thrones.
Peter (Spanish: Pedro; 30 August 1334 – 23 March 1369), called Peter the Cruel (el Cruel) or the Just (el Justo), was King of Castile and León from 1350 to 1369. Peter was the last ruler of the main branch of the House of Ivrea. He was excommunicated by Pope Urban V for his persecutions and cruelties committed against the clergy.
Henry II (13 January 1334 – 29 May 1379), called Henry of Trastámara or the Fratricidal (el Fratricida), was the first King of Castile and León from the House of Trastámara. He became king in 1369 by defeating his half-brother Peter the Cruel, after numerous rebellions and battles. As king he was involved in the Fernandine Wars and the Hundred Years' War.
