ALPHONSO IV (924-931)
has a faint personality. He resigned the crown to his brother
Ramiro and went into a religious house. A certain instability
of character is revealed by the fact that he took up arms
against Ramiro, having repented of his renunciation of the
world. He was defeated, blinded and sent back to die in the
cloister of Sahagun.
