On December 6, 1768, the first volume of the first edition of the Encyclopaedia Britannica was published in London as , 'A Dictionary of Arts and Sciences, compiled upon a New Plan'. The Britannica is the oldest English-language encyclopaedia still being produced today. The history of its 15 editions alone would be subject of an entire book. But although it might be the most popular encyclopaedia ever printed, it was not the first.
On January 18, 1698, French philosopher and political thinker Charles-Louis de Secondat, baron de La Brède et de Montesquieu, generally only referred to as Montesquieu, was born. He is best known for his articulation of the theory of separation of powers, which is taken for granted in modern discussions of government and implemented in many constitutions throughout the world.
