Ancient Diocese of Die

[7] On 28 March 1165 Pope Alexander III confirmed by papal bull the grant to the Church of Die on the part of Arnaud de Crest[8] and Guillaume of Poitiers[9] of the abbeys of S. Marcel de Die,[10] Saint-Medard, Saint-Croix, Saint Julien-de-Guiniaise, Leoncel, and Saou.

[7] The Huguenot sect, derived from the Calvinism of Geneva, had taken firm hold in the Dauphiné, and in particular in the Alpine valleys.

From the point of view of the Roman Catholic Church, however, the union of the two dioceses was dissolved canonically in the Consistory of 7 July 1692 by Pope Innocent XII.

[15] On 10 September 1692, the Bishop of Die, Armand de Montmorin Saint-Hérem, had an interview with James II of England and Louis XIV.

Bishop Gaspard-Alexis Plan des Augiers protested, and then fled his diocese; he died in exile in Rome in 1794.

On 21 February 1791, the Constitutional diocese of Drôme elected François Marbos, curé of the parish of Bourg-lez-Valence as their 'bishop'.

[17] The Carthusian who went by the pseudonym Polycarpe de la Rivière gives a St. Martinus (220) as first Bishop of Die; his assertion has been doubted.
