Sancho IV
In 1291, the truce with Sancho IV of Castile expired, so hostilities in Spain were renewed. While Abu Yaqub was busy against Tlemcen, Sancho IV conspired with the Nasrid sultan Muhammad II of Granada to seize the three remaining Marinid citadels in Spain - Tarifa, Algeciras and Ronda - for themselves. With Granadine assistance, the Marinid citadel of Tarifa fell to Sancho IV in October 1292. But Sancho refused to honour his agreement to hand the citadel over to Granada and instead he decided to keep Tarifa for himself.
