Etymology: Charles-Louis de Secondat inherited the title Baron de Montesquieu from his family's estate near Bordeaux, and it is the name the world remembers him by. He was born at the château de La Brède, trained as a lawyer, and served in the Bordeaux parlement before he turned to writing. His most influential book, "De l'esprit des lois" (The Spirit of the Laws), argued that liberty is safest when legislative, executive and judicial powers are held by separate bodies, so that each can check the others. He drew heavily on his reading of the English constitution. The idea had earlier roots, but his treatment of it shaped how later constitutions were written, including that of the United States. Reformers and writers quoted him so often that his name became shorthand for the doctrine itself.

Synonyms: Charles-Louis de Secondat, Baron de Montesquieu
