Fernando Ansúrez II

Fernando Ansúrez II (died 978, shortly after 23 April) was the Count of Monzón, Peñafiel, and Campos from 950 and one of the most powerful noblemen of his generation in the Kingdom of León. He was the eldest son of Ansur Fernández and namesake of his grandfather, Fernando Ansúrez I. His sister Teresa was the queen of Sancho I and later regent for her son, Ramiro III.

Fernando had six brothers (Oveco, Gonzalo, Osorio, Muño, Gutier and Nuño) at the time of his first appearance in contemporary records (943), but shortly after being appointed to the county of Monzón (951) only two, Gonzalo and Muño, were still living, and they were recorded as counts along with him. The first record of Fernando as count is his confirmation of a diploma of 17 June 950, where he signs as Fredinandus Assurez comes. Fernando probably succeeded his father, with royal approval, but there is a lapse in the documentation concerning the county of Monzón between 947 and 950.
