The Roman Catholic Diocese of Baeza (Latin: Beatia) was a Visigothic Catholic bishopric, suppressed under Moorish rule and shortly restored in the 13th century, which remains a Latin titular see.
Some claim that Ancient Roman Beatia became the seat of a bishop in the Visigothic Kingdom of Toledo between 656 and 675, when the Diocese of Castulo was transferred to Beatia, on territory previously belonging to the Diocese of Tucci.
In 715 was established a Diocese of Baeza / Beatia (Curiate Italian = Latin) / Biatien(sis) (Latin adjective) in its own right, on canonical territory split off from the suppressed Diocese of Tucci, as a suffragan of the Archbishopric of Toledo (in the Visigothic and later Castilian royal capital), but the Moorish rule (since 711) doomed it after a few more bishops, including martyrs.
In 900 the bishopric was suppressed, but king Alfonso VIII of Castile (1158-1214) still mentions it in his Chronicle.
The diocese was shortly restored from 1227, when the Baeza Cathedral, then dedicated to the Assumption of Mary (which the Moors had turned into a mosque), was reinstated (Catedral de la Asunción de la Virgen), until 1249, when the see was transferred for good and its territory merged into the Roman Catholic Diocese of Jaén. The former cathedral, although a Minor World Heritage Site (since 2003 part of a UNESCO World Heritage Site with other monuments in Baeza and in the nearby city of Úbeda), never became a (co-)cathedral again.
