A naval administrator who served as commissioner at Saint-Domingue from 1767 and afterwards at Cayenne, Malouet acquired plantations through his marriage and argued in a memoir of 1788 for the amelioration rather than the abolition of colonial slavery. Elected for the Third Estate of Riom, he opposed issuing a declaration of rights in advance of the constitution and supported an absolute royal veto and two chambers, leading the Impartiaux and later the Monarchical Club. He was the chief parliamentary support of the Saint-Domingue proprietors against the Amis des Noirs. Emigrating in 1792, he asked to be heard in defence of Louis XVI and later negotiated the placing of Saint-Domingue under British protection. He served Napoleon as maritime prefect at Antwerp and became minister of marine in May 1814, dying in office that September.
