Peter III of Aragon (In Aragonese, Pero; in Catalan, Pere; in Italian, Pietro; c. 1239 – November 1285) was King of Aragon, King of Valencia (as Peter I), and Count of Barcelona (as Peter II) from 1276 to his death. At the invitation of some rebels, he conquered the Kingdom of Sicily and became King of Sicily in 1282, pressing the claim of his wife, Constance II of Sicily, uniting the kingdom to the crown.
