Charles Louis de Secondat, Baron de La Brède et de Montesquieu, was a French judge and political philosopher. 
Montesquieu was born on January 18, 1689, at the Château de la Brède. 
His early life coincided with major shifts in European government. England became a constitutional monarchy following the Glorious Revolution.
Montesquieu became a successful author with his 1721 book, *Persian Letters*. This work was a satire that criticized French society through the eyes of two Persian visitors. In 1728, he began a grand tour of Europe with a traveling companion. 
His most famous theory is the separation of powers, or *trias politica*.
Montesquieu's ideas reached far beyond the borders of France. In the British colonies of North America, he was a major authority on politics. One study found he was the most frequently quoted source on government in colonial America, second only to the Bible.
Montesquieu also had a unique philosophy regarding the movement of history. He argued that history is not driven by mere chance or accidents. Instead, he believed that "general causes" drive the rise and fall of nations. In his book about the Romans, he suggested that human nature drives events. For example, he believed the ambition of men was a cause of change. He thought that if one leader did not seize power, another person would have done the same. This view focused on large social movements rather than just individual people.
In his later years, Montesquieu suffered from a cataract and feared losing his sight. He visited Paris in late 1754 and soon became ill. He died from a fever on February 10, 1755.
