It was founded in 1777, followers of the Greek Rite having been up to that time under the jurisdiction of the Latin bishop. Originally the see was a suffragan of Esztergom (Gran); when, however, in 1853 the Greek Catholic Diocese of Făgăraș and Alba Iulia became the Archdiocese of Făgăraș and Alba Iulia, the diocese of Oradea Mare was transferred to its jurisdiction.[1] The see is divided into six archidiaconates and 19 vice-archidiaconates.
