Roman Catholic Diocese of Aire and Dax

The Diocese of Aire and Dax (Latin: Dioecesis Adurensis et Aquae Augustae; French: Diocèse d'Aire et Dax) is a Latin Church ecclesiastical territory or diocese of the Catholic Church in France. It comprises the département of Landes, in the région of Gascony in Aquitaine.

It was a suffragan diocese of the Archdiocese of Auch under the Ancien Régime, but was not re-established until 1822, when it was again made a suffragan of the re-established Archdiocese of Auch, and was assigned the territory of the former Diocese of Aire and Diocese of Acqs (Dax). It is now a suffragan in the ecclesiastical province of the metropolitan Archdiocese of Bordeaux.

It has been known since 1857 as the Diocese of Aire and Dax. It is a co-cathedral diocese, with cathedras in the Cathedral St-Jean-Baptiste d' Aire and in Nôtre Dame de Dax.

On April 6, 2017, the resignation letter of recent Bishop Herve Gaschignard was officially accepted by Pope Francis following allegations that Gaschignard engaged in inappropriate behavior with young people.

History
The first reference to a bishop of Aire, on the river Adour, in history is to Marcellus, represented at the Council of Agde, 506. Aire was also the home of St. Philibert; it numbered among its bishops during the second half of the sixteenth century François de Foix, Count of Candale, an illustrious mathematician, who translated Euclid and founded a chair of mathematics at the University of Bordeaux, though he never visited his diocese.

In 1572, on the death of Bishop Christophe de Candale, the Capitular Vicar of Aire submitted a status report (pouillé) to King Charles IX, providing a picture of the diocese at that time. There were two Archdeacons, that of Marsan and that of Chalosse. In addition to the two archdeacons, the Cathedral Chapter was composed of ten Canons and seven Prebendaries, two semi-Prebendaries, the Master of the Children of the Choir, and the Basse-Contre. The Statutes of the Chapter were confirmed by Bishop Tristan d'Aure in 1459 or 1460.

 * the Abbaye du Mas d'Aire (O.S.B.: four religious, a Prior, a Sacristan, a Chamberlain and an Almoner; eleven other positions vacant)
