1727–1796
A soldier, planter, and political economist of the late Enlightenment, he wrote sharply about public debt, taxation, and the forces that shape societies. His work brought together colonial experience, financial argument, and big ideas about how nations rise and falter.

by marquis de Charles Casaux
Born in 1727 in Guadeloupe, the Marquis de Casaux — also known as Alexandre Cazeau de Roumillac — was a French military officer, colonial planter, and writer on political economy. He later lived in London and was elected a Fellow of the Royal Society in 1780, a sign of the attention his ideas attracted in intellectual circles.
Casaux is best known for Thoughts on the Mechanism of Societies, a work that examines public finance, taxation, and national debt. Writing in the late eighteenth century, he argued that economic policy could shape the strength or decline of whole societies, and his ideas were noted by later readers including Mirabeau.
His life also reflects the wider world of the Atlantic eighteenth century: born in the Caribbean, involved in colonial plantation society, and active in Britain as well as France. He died in London in 1796, leaving behind a small but distinctive body of work that connects economics, politics, and the history of empire.
