oldest sons: Alfonso III of Aragon, who received the crown of Aragon, and James II of Aragon, who succeeded as King of Sicily. Honorius IV acknowledged neither the one nor the other: on 11 April 1286, he solemnly excommunicated King James II of Sicily and the bishops who had taken part in his coronation at Palermo on 2 February.
