Abu Yusuf
In 1272, the Nasrid ruler Muhammad I of Granada had appealed to the Marinid emir Abu Yusuf Yaqub for assistance. Granada was then plunged in civil war, with the Nasrids fighting off a challenge from the rival Banu Ashqilula family, rulers in Málaga, Guadix and Comares. The Christian king Alfonso X of Castile had thrown his weight behind the Ashqilula – in part because the Nasrids themselves had sheltered Castilian rebels. But the Marinid emir Abu Yusuf was then engaged against Tlemcen and could not intervene.
