What it is
Claude Fleury's celebrated catechism, first published in 1679, taught Christian doctrine by narrating the full arc of salvation history through the Old and New Testaments before moving to doctrinal instruction on the commandments, sacraments, and prayer. Its narrative-first method distinguished it sharply from the question-and-answer catechisms dominant since Trent. Alongside Bossuet's Meaux catechism, it was a named source for the drafters of Napoleon's Imperial Catechism of 1806, with new editions appearing in 1803, 1805, and 1806 — precisely the years of Napoleon's catechetical project. Its wide use in French royal education from Louis XIV onward gave it a continuous institutional life across regime changes, even after its placement on the Index Librorum Prohibitorum.
Why it still matters
Fleury's approach — grounding doctrine in salvation history rather than bare definition — remains especially effective for children's formation and adult inquiry; a catechist today can follow his sequence from Genesis through the Apostolic church before introducing the creed, commandments, and sacraments.

Catéchisme du diocèse de Meaux (Bossuet's Catechism)
Catéchisme du diocèse de Meaux
Bossuet's landmark Gallican catechism, composed 1685–1686 and published in 1687, was one of the two primary sources — alongside Fleury's Catéchisme historique — from which Napoleon's mandatory Imperial Catechism of 1806 was directly derived. The Organic Articles of 1802 specified that the Empire's single catechism should be drawn from existing Gallican models; the drafting commission under Abbé d'Astros explicitly revised and condensed Bossuet and Fleury for that purpose. The work comprises nineteen lessons of basic doctrine, an advanced catechism, morning prayers, and a catechism of feasts and Sundays, all in Bossuet's celebrated plain and luminous French prose. Its Gallican ecclesiology was also mandated teaching in all French seminaries under the Organic Articles, giving it an institutional reach well beyond Meaux diocese.
Imperial Catechism (Catéchisme impérial)
Catéchisme à l'usage de toutes les Églises de l'Empire français
Napoleon's mandatory catechism for all churches and schools of the Empire, derived primarily from the Gallican catechisms of Bossuet and Fleury and imposed by imperial decree of 4 April 1806. At Napoleon's personal insistence, Lesson VII on the Fourth Commandment required every Christian to owe the Emperor 'love, respect, obedience, fidelity, military service and taxes,' framing Napoleon as God's anointed image on earth. Children across the Empire were required to memorize it; Cardinal Caprara approved it without prior papal consultation on 30 March 1806, and Pope Pius VII's reservations over the text contributed materially to the rupture of 1809. The catechism replaced all existing diocesan catechisms by force of law throughout French-controlled territory.
Religious Education of Napoleon II (King of Rome / Duke of Reichstadt)
[Bibliothèque religieuse du Roi de Rome, Vienna, c. 1814–1820]
After Napoleon's abdication in 1814, his son Napoleon II (born 1811, King of Rome) was raised at the Habsburg court in Vienna under Emperor Francis I with the title Duke of Reichstadt. Governess Madame de Montesquiou assembled an initial religious library intended to ground the child in religion, philosophy, and military subjects, and by age ten he was formally studying religion alongside Latin, Greek, Italian, history, and natural sciences. The specific catechisms and devotional texts used would have been standard Habsburg court Catholic formation materials — likely including the Austrian imperial catechisms of the period — but no inventory of his particular religious library has been identified in any accessible primary source. The connection to the Bonaparte house is by dynastic lineage; the texts themselves were Austrian Habsburg court materials.
