Tarentaise comprises the arrondissement of Moutiers in the Department of Savoie; it is also sometimes called the Diocese of Moutiers en Tarentaise, and is suffragan of Chambéry. Legend relates that the "Centrones" were evangelized in the fifth century by James the Assyrian secretary to St. Honoratus, Archbishop of Arles. He became the first Bishop of Darantasia or Tarentaise, the metropolis of the "Centrones", and named St. Marcellus as his successor. The first document in which the Diocese of Tarentaise is reliably mentioned is a letter of Leo the Great (5 May, 450) which assigns to the Archdiocese of Vienne, among other suffragans, the Bishop of Tarentaise. The first historically known bishop is Sanctius who in 517 assisted at the Council of Epaon. A plea was brought before the Council of Frankfort (794) against the decision of Leo I that had been confirmed by Popes Symmachus and Gregory the Great. Leo III partly acceded to this plea, and made Darantasia a metropolis with three suffragans, Aosta, Sion, and Maurienne, but maintained the primacy of Vienne. For four centuries this primacy was the cause of conflicts between the archbishops of Tarentaise and those of Vienne; subsequently Maurienne was again attached to the metropolis of Vienne.

The city of Darantasia was destroyed by the Saracens in the tenth century, whereupon the archbishops moved their residence to the right bank of the Isére, calling it their moutier (monastery), and it was at this place that the town of Moutiers began to be built in the second half of the tenth century. In the twelfth century the archbishops of Tarentaise were powerful sovereigns. In 1186 a bull of Frederick Barbarossa recognized the Archbishop of Tarentaise as immediate vassal of the empire and prince of the Holy Roman Empire in disregard of the pretensions of Humbert III, Count of Savoy; but in 1358 a transaction between Archbishop Jean de Bertrand and the Count of Savoy, Amadeus VI, fixed the respective rights of the archbishops and the counts. Tarentaise belonged to France from 1536 to 1559, and from the sixteenth to the eighteenth century was on four occasions wrested for a time by France from the House of Savoy. In 1792 it formed the Department of Mont Blanc. The Treaty of Paris (30 May, 1814) gave it to the King of Sardinia, while the Plebiscite of 22 and 23 April, 1860, gave it to France. The Archdiocese of Moutiers in Tarentaise was suppressed in 1792 by the French Revolution. In 1825 a diocese was re-established at Moutiers, suffragan of Chambéry, and was maintained in 1860 in virtue of a special clause in the treaty ceding Savoy to France.

Among the archbishops of Moutiers in Tarentaise may be mentioned: St. Peter I (about 1130), the first Cistercian raised to the episcopate, who founded in a defile the Cistercian Abbey of Tamié, to serve as a shelter for pilgrims and travellers; the Cistercian monk St. Peter II (1141-74) founded the charity of the pain de Mai, which until the second half of the eighteenth century distributed bread at Moutiers at the expense of the archdiocese during the first twenty-eight days of May; it was he who upheld Alexander III against Frederick Barbarossa and the antipope Victor IV, and maintained in obedience to Alexander III the seven hundred abbeys of the Cistercian Order. Alexander decided (3 Feb., 1171) that thenceforth the metropolitan See of Tarentaise should depend only on Rome; St. Peter III (1271-83); Cardinal Antoine de Chalant (1402-18), to whom has been ascribed "Le livre du Roi Modus et de la reine Ratio", a much-esteemed treatise on hunting; Cardinal Jean d'Arces' (1438-54), who at the Council of Basle in 1440 supported Duke Amadeus of Savoy, antipope under the name of Felix V, against Eugene IV; Cardinals Christopher and Dominic de la Rovére (1472-78 and 1478-83), whose tomb erected at Rome in the Church of Santa Maria del Popolo is a splendid monument of the Renaissance; Germonio (1607-27), who played an important part in the seventeenth-century reform of the clergy and whose "Commentaries" and "Acta Ecclesiæ Tarentasiensis" are important documents for the history of the time. As natives of the diocese may be mentioned: Pope Nicholas II (1059), born at Chevron-Villette of the family of the lords of Miolans; Pierre d'Aigueblanche, who in 1240 became Archbishop of Hereford in England, and for twenty-five years was councillor and minister to Henry III of England; Blessed Peter of Tarentaise, who became pope in 1276 under the name of Innocent V.

The chief pilgrimages of the diocese are: Notre Dame de Briançon, which dates from the victory over the Saracens in the tenth century. Francis I and Henry IV visited this shrine; Notre Dame des Vernettes, at Peisey, created in the eighteenth century near a miraculous fountain; Notre Dame de la Vie at St. Martin de Belleville; Notre Dame de Beaufort; St. Anne at Villette dating from 1248. Before the application of the Law of 1901 regarding associations there were in the diocese Augustinians of the Assumption, Capuchins, and two orders of teaching brothers. The Sisters of St. Joseph, nursing and teaching sisters, separated in 1825 from the Congregation of Puy. Several hospitals and schools in Brazil are dependent on their mother-house at Moutiers. At the end of the nineteenth century religious congregations in the diocese were charged with: 4 infant schools, 2 orphanages for girls, 6 infirmaries or hospitals, 4 houses of retreat. In 1905 (end of the period of the Concordat) the diocese numbered 68,000 inhabitants, 7 parishes, 79 succursal churches, and 21 vicariates remunerated by the Government.
