Claude Fleury (6 December 1640, Paris – 14 July 1723, Paris), was a French ecclesiastical historian.
Destined for the bar, he was educated at the aristocratic College de Clermont (now that of Louis-le-Grand).
In 1658 he was nominated an advocate to the parlement of Paris, and for nine years followed the legal profession.
But he had long been of a religious disposition, and in 1667 turned from law to theology.
Fleury's evident intention was to write a history of the church for all classes of society; but at the time in which his great work appeared it was less religion than theology that absorbed the attention of the clergy and the educated public; and his work accordingly appealed to the student rather than to the popular reader, dwelling as it does very particularly on questions of doctrine, of discipline, of supremacy, and of rivalry between the priesthood and the imperial power.
Nevertheless, it had a great success.
The first edition, printed at Paris in 20 volumes (4to), 1691, was followed by many others, among which may be mentioned that of Brussels, in 32 vols (8vo), 1692, and that of Nîmes, in 25 vols (8vo), 1778 to 1780.
The work of Fleury only comes down to the year 1414.
It was continued by Jean Claude Fabre and Goujet down to 1595, in 16 vols.
(4to).
In consulting the work of Fleury and its supplement, the general table of contents, published by Rondet, Paris, 1758, 1 vol.
(4to) will be found very useful.
Translations have been made of the entire work into Latin, German and Italian.
The Latin translation, published at Augsburg, 1758–1759, 85 vols.
(8vo), carries the work down to 1684.
Fleury was appointed confessor to the young King Louis XV in 1716, because, as the duke of Orleans said, he was neither Jansenist nor Molinist, nor Ultramontanist, but Catholic.
