It was part of the civil war which engulfed the Kingdom of Castile following the death of Sancho III (1158), wherein competing factions sought control of his minor son and successor, Alfonso VIII.
Fernando was with the court of León at least as late as 16 April, but by early summer he was in the castle of Huete in Toledo amassing forces for an invasion of Castile.
In the words of the Chronica latina regum castellae, "at that time Count Manrique fought against Fernando Rodríguez, who had with him the people of Huete.
[4] According to the late Crónica de Veinte Reyes Manrique demanded that Fernando turn over the castle of Huete, but the latter refused, citing Sancho III's command that tenants should continue to hold their royal fiefs until Alfonso VIII came of age.
After Manrique's death, his brothers led the retreat to Zorita with the king and from there to Ávila, where the prelates with them negotiated their reception and afterwards a cessation to hostilities.
Fifteen and three days before this charter was made [3 June] Count Don Manrique and his knights were killed.
