Peter of Barcelona
Peter of Aragon (Spanish: Pedro de Aragón, Italian: Pietro d'Aragona, Catalan: Pere d'Aragó, Aragonese: Pero d'Aragón; 4 May 1152 - c.1164) was an Aragonese Infante as the oldest son and first child of Queen Petronilla of Aragon and her king consort, Ramon Berenguer IV, Count of Barcelona.
Not much information about Peter survives, but it is known for sure that he existed. The Corónicas Navarras names all of Petronilla's children, in order, as don Pedro…el rey don Alfonso, que ovo nombre Remón Belenguer et el conte don Pedro de Provença et el conte don Sancho et a la muller del rey don Sancho de Portugal. Peter was named Count of Cerdanya, Carcassonne and Narbonne.
Some sources state that Peter died in 1157, sometime after King Alfonso VII of León and Castile died. This year of death is also likely since the third son, also named Peter, was born in 1158. It is certain that the elder son Peter was dead by 18 July 1164, as his mother abdicated in favour of his younger brother, Ramon, rather than Peter, who had been named heir of Aragon at birth. The Corónicas Navarras also stated that Peter died in Huesca.
