In 1298 the fleet of James II of Aragon (1267-1327) was ordered to attack his brother Frederick II of Sicily (1272-1337), also known as Frederick III, for his refusal to comply with the Treaty of Anagni (20 june 1295). Part of the fleet, commanded by Juan of Lauria, nephew of Admiral Roger of Lauria, was defeated near Messina, being taken prisoner along with many others. Frederick ordered Juan de Lauria to be beheaded, provoking the reaction of King James II and Admiral Roger of Lauria, who attacked and completely defeated the Sicilian fleet in 1299.
