Marcellus I, the first known
bishop of Senez, attended the
Council of Agde in 506 CE; nevertheless, Senez must have been an episcopal city as early as 439 CE. Jean IV Soanen, the
Oratorian, noted for his opposition to the Bull "Unigenitus", was Bishop of Senez from 1696 until the time of his deposition in 1727. By the Concordat of 1801, the
diocese of Digne was made to include the two departments of the
Hautes-Alpes and
Basses Alpes, in addition to the former diocese of Digne, the
archdiocese of Embrun, the dioceses of
Gap,
Sisteron, and Senez, a very considerable part of the
diocese of Glandèves and
diocese of Riez, and fourteen parishes in the
Archdiocese of Aix and the
Diocese of Apt. In 1822 Gap was made an episcopal see and, thus divested of the department of the Hautes Alpes, the present diocese of Digne covers the territory formerly included in the dioceses of Digne, Senez, Glandèves, Riez, and Sisteron. ==Demographics==
