Who was Montesquieu?
Charles-Louis de Secondat, Baron de Montesquieu, was born near Bordeaux, studied law and inherited a seat as president of the Parlement of Bordeaux. His satirical Persian Letters (1721) made him famous, and after years of travel, including a long stay in England, he published The Spirit of the Laws in 1748. The book classifies governments as republics, monarchies and despotisms, each with its own guiding principle, and studies how climate, geography, religion and commerce shape laws. The Catholic Church placed it on the Index of Forbidden Books in 1751.

Legacy
Montesquieu's separation of powers deeply influenced the framers of the United States Constitution, who cited him frequently, and it shaped constitutional design in many later democracies. Liberals credit him with a durable theory of limited government, and conservatives value his attention to custom, tradition and gradual reform. Critics have argued that his reading of the English constitution was idealized, that his climate theory relied on stereotypes about peoples and regions, and that his defense of aristocratic privilege sat uneasily with equal rights. Sociologists also treat him as an early comparative social scientist.
In their words
To prevent this abuse, it is necessary from the very nature of things that power should be a check to power.
