Rodrigo Muñoz, son of Count Munio González and Mayor Muñoz, was a Castilian magnate in the kingdoms of León and Castile.
Education
He married a woman named Teresa sometime before March 1103, when they completed an exchange of properties (their land at Oreña for an estate in the Toranzo valley) with the monastery of Santillana del March As early as 1104 he was ruling Asturias de Santillana, the eastern part of Asturias, bordering northwestern Castile.
Career
His tenancies were mostly in Cantabria, in the northern Castilian lands bordering the Basque country. Rodrigo"s daughter, called Mayor or Guntroda, married Pedro Fróilaz de Traba, a powerful Galician magnate, sometime before May 1105. By September 1105 Rodrigo had been appointed a count (Latin comes or consul) by Alfonso VI. This was the highest rank in Castile during the twelfth century.
By February 1109 Rodrigo was also ruling Liébana in the far west of Castile.
The day after the king"s burial, 22 July 1109, Urraca confirmed all the privileges of the Diocese of León. Rodrigo was then present.
On 11 August 1111, in a donation of Urraca to Santillana del March, he was cited as "Count Don Rodrigo of Asturias". By February 1112 he was governor of the Trasmiera, the Castilian lands north of the Miera river.
He may have been displaced in Asturias by Rodrigo González de Lara, although this may have been brief: there is a royal charter of January 1113 that records Rodrigo Muñoz as count in Asturias.
In May 1112 a certain count Rodrigo confirmed two royal charters as ruling in castella, "in Castile", that is, Old Castile. This may have been either Rodrigo Muñoz or Rodrigo González. Another charter, from late 1110, calls Rodrigo Muñoz "Count of Castile", but its accuracy is questionable.
The last record of Rodrigo ruling in Asturias dates from February 1116.
The last record of Rodrigo alive dates to July. One charter referring to comite Rodericus Munioz totius Asturiensis (count Rodrigo Muñoz of all Asturias) is misdated to 1082.
