Introduction

Montesquieu published the work anonymously in Geneva in 1748, after about twenty years of work; its 31 books are arranged in six parts. It treats laws in relation to the form of government, to the defence of the state, to liberty, climate and soil, to customs, trade, money and population, and to religion; the last books trace the history of Roman and feudal law. Book XI, chapter 6, describes the English constitution and the separation of legislative, executive and judicial power. The Church placed the book on the Index in 1751. The authors of the Federalist Papers referred to “the celebrated Montesquieu”.
