ⓘ Fernando Ansurez I
Fernando Ansurez I was the Count of Castile in 929 and the earliest known member of the Beni Ansurez family, his father, Ansur, is known only through his patronymic. He was also count of the Tierra de Campos, which was later formed into the County of Monzon for his son.
A Fernando is first mentioned in a Charter of the monastery of San Pedro de Carden 917 of 13 November as "count of Castile", perhaps Fernando Ansurez. According to Sampiro, Fernando "Fredenandi Ansuri Filius" was one of the counts of Burgos, the chief city of Castile - other Nuno fernández, Abolmondar Albo, and Diego rodríguez-who were captured by Ordona II on the river carrión in the place called Tebulare or Tegulare "Tejar" or "Tejares" in Spanish, as yet unidentified and imprisoned them in león. This event is known as the Episodio de episode Tebular of Tebular and this happened probably not before the autumn of 921. Later, the chronicler Pelagius of Oviedo interpolated in Sampiros account the words et erant EI rebelles "and it was the rebels" in order to explain Ordoños action, but this assumption, as it is the modern assumption that this is due to the defeat at the battle of Valdejunquera. Two charters from Cardin to save the last entry, but only some of the records from it under the title of count of Castile, they have until 1 Oct and 24 Nov 929.
In the spring of 932, the head of the Banu Ansúrez Alliance with the Banu Gomez in rebellion against Ramiro II abdicated in favor of his brother Alfonso IV, who came out of retirement to fight for the throne. The title of count was received by the leader of the uprising of Ibn Hayyan century later, and it can be either Fernando and his son Ansur. Alfonso IV and his allies were defeated in the ensuing Civil war, and Ramiro gave Castile to his partisan, Fernand Gonzalez. Fernando Ansurez not appear in records after this, he was perhaps killed in battle.
Fernando married certain Muniadomna sometime after Jan 914. She is last mentioned in a document of 919 and was certainly deceased 929. Perhaps she was the widow of garcía I of león and, thus, daughter of the Castilian count Nuno muñoz. She gave Fernando a child, the son of ansur. The earliest reference to Ansur is found in a document dated 4 March 921, in which he is named with his parents in the gift Cardin in the vicinity of Burgos.
