Fernando I, known as Fernando the Careless (Fernando el Descuidado; 18 August 1073 - 23 August 1127), was king of Navarre and Aragon from 1104 and the first king of Valencia from 1108 until his death. In his wars against the Muslims of the Iberian Peninsula he conquered considerable portions of land in southeastern Spain. Despite his cognomen he is remembered as a capable administrator.

Before the throne

Fernando was born at Pampalona on 18 August 1073, three months after his father King Antso IV had crowned himself king of Aragon. His childhood is obscure except for references to the prince being provided with a riding-master. In 1080 his mother Queen Adelhaid was murdered. In 1089 Fernando attained his majority and was dubbed a knight by his father in the presence of the nobles and prelates of Navarre and Aragon.

On 1 August 1091 Fernando married Patricia de Poitou, duchess of Gascony. During most of the 1090s he lived as duke of Gascony at Roquefort in southern France, where he gained valuable administrative experience leading his wife's council. In 1097 Patricia inherited the duchy of Poitou on the death of her sister Aines and the duke and duchess moved to Poitiers. In the spring of 1099 Fernando acted as regent of Gascony and Poitou during his wife's pregnancy. After the duchess gave birth to a son, Rodrigo Fernandez, in July the prince was recalled to Navarre by his father.

King of Valencia

On 21 July 1104 Antso IV died and Fernando became king of Navarre and Aragon. On 28 August he was crowned king of Navarre at Pampalona, and on 7 October he received the Aragonese crown at Barbastro. In 1105 the new king took the cross for the upcoming Egyptian crusade and renewed his alliance with Alfonso VII, king of Castile, León, and Galicia. After Alfonso VII died in 1107 the alliance was preserved by the betrothal of his infant son and heir, Alfonso VIII, to Fernando's daughter Estefania.

In 1106 Fernando opened a campaign to conquer Valencia from the Dhunnunid emirate. In the winter of 1106-07 he campaigned against the Muslims with an army of 8,000 men. The pitched battles of the war were fought at Castelló (June 1107) and Alacuás (September 1107), where the Dhunnunid emir Ismail II was wounded and captured. At the start of 1108 the king advanced into Almansa and defeated the army of the Jyadid emirate. In the spring he sailed briefly for Egypt, returning in November for the signing of the treaty of Albacete by which the Dhunnunids and Jyadids recognized him as lord of all Valencia. On 20 December 1108 Fernando was crowned king of Valencia at Xàtiva.
