MontesquieuCharles Louis de Secondat, Baron de La Brède et de Montesquieu (ʃaʁl lwi də səɡɔ̃da baʁɔ̃ də la bʁɛd e də mɔ̃tɛskjø; 18 January 1689 - 10 February 1755), generally referred to as simply Montesquieu (ˈmɒntəskjuː, ˌmɒntEˈskjɜː, mɔ̃tɛskjø), was a French judge, man of letters, historian, and political philosopher. He is the principal source of the theory of separation of powers, which is implemented in many constitutions throughout the world. He is also known for doing more than any other author to secure the place of the word despotism in the political lexicon.
American RevolutionThe American Revolution was an ideological and political revolution that generally occurred in British America between 1765 and 1783. In the American Revolutionary War, which lasted from 1775 to 1783, the Thirteen Colonies secured their independence from the British Crown and established the United States as the first sovereign nation state founded on Enlightenment principles of constitutionalism and liberal democracy. American colonists objected to being taxed by the British Parliament, a body in which they had no direct representation.
French RevolutionThe French Revolution (Révolution française ʁevɔlysjɔ̃ fʁɑ̃sɛːz) was a period of radical political and societal change in France that began with the Estates General of 1789 and ended with the formation of the French Consulate in November 1799. Many of its ideas are considered fundamental principles of liberal democracy, while the values and institutions it created remain central to French political discourse. Its causes are generally agreed to be a combination of social, political and economic factors, which the Ancien Régime proved unable to manage.
