The Diocese of Huesca (Latin, Oscensis) is a Latin Church ecclesiastical territory or diocese of the Catholic Church located in north-eastern Spain, in the province of Huesca, part of the autonomous community of Aragón. The Diocese of Huesca is a suffragan diocese in the ecclesiastical province of the metropolitan Archdiocese of Zaragoza. The diocese encompasses parts of the province of Huesca in north-eastern Spain, seven parishes in the Broto valley and three within the territorial limits of the Archdiocese of Saragossa, one parish being situated in the city of Saragossa itself. The Diocese of Huesca was created in or before the 6th century; after the Moorish conquest of 713 its bishops moved to Aragon (the itinerant "Bishops of Aragon"). The episcopal seat was established in Jaca during 1063-1096, then finally moved back to Huesca after king Pedro I of Aragon took the city from the Moors in November 1096. History Early history (c. 500 – 713) The date of origin of the diocese cannot be definitely ascertained; the earliest evidence of its existence is the signature of Gabinius, Bishop of Huesca, to the decrees of the Third Council of Toledo, held in 589. Isidore of Seville, writing in the 7th century, mentions the presence of Elpidius, Bishop of Huesca, at an earlier council, but this is not considered authoritative. The year of the diocese being erected is given as 533. After 589, we next hear of the diocese through a synod held there in 598 which ordered annual diocesan conferences and enacted various disciplinary measures. Itinerant bishops of Aragon (713–1063) The Moorish invasion of 710 rapidly worked toward Huesca; when the city was taken in 713 the bishop fled, and the diocese was directed from Aragon by itinerant bishops, sometimes called bishops of Aragon, sometimes bishops of Huesca or Jaca, who lived either at Jaca or in the neighbouring monasteries of San Juan de la Peña, San Pedro de Siresa, and San Adrián de Sasabe. Among the bishops of Aragon were: . c. 920 : Iñigo . c. 922 : Ferriolus 933–947 : Fortuño 971–978 : Aureolus . c. 981 : Atón 1011–1036 : Mancius 1036–1057 : García 1058–1075 : Sancho 1076–1086 : García Ramírez 1087–1097 : Peter Jaca as seat of the bishops of Huesca (1063–1096) A council held at Jaca in 1063 determined anew the boundaries of the Diocese of Huesca, which thereafter included the present dioceses of
