Abu Yusuf
The Marinid emir Abu Yusuf defeated a large Castilian army under Nuño González de Lara "el Bueno", "adelantado de la frontera", in the pitched Battle of Écija in September. A second army led by the Archbishop Sancho II of Toledo in October met a similar fate. Only the rapid rallying of Castilian forces by infante Sancho kept the Marinids from doing more damage. Alfonso X arrived back in Castile at the end of the year and negotiated a truce with Abu Yusuf Yaqub.
