Guy-Marie Deplace

Born in 1772 and dying in 1843, Guy-Marie Deplace was a French Catholic ecclesiastic and author whose career unfolded during one of the most unsettled periods in French religious history. He is chiefly associated with De la persécution de l'Église, sous Buonaparte, a work that reflects his strong concern for the fate of the Church in Napoleonic France.

Available sources point to him as both a man of religion and a polemical writer, shaped by the aftermath of the French Revolution and the conflicts between Church and state that followed. His writing suggests a deeply committed Catholic perspective and an interest in defending the Church's experience and memory in a politically charged era.

Although detailed biographical information is limited in the sources readily available online, his surviving work gives a clear sense of his place in history: a cleric-author writing from within the struggles of his time, and leaving behind testimony to the religious debates of early modern France.
