Alexis-Charles-Henri Clérel de Tocqueville (French pronunciation: ; 29 July 1805, Paris – 16 April 1859, Cannes) was a French political thinker and historian best known for his Democracy in America (appearing in two volumes: 1835 and 1840) and The Old Regime and the Revolution (1856). In both of these works, he explored the effects of the rising equality of social conditions on the individual and the state in western societies. Democracy in America (1835), his major work, published after his travels in the United States, is today considered an early work of sociology and political science.
An eminent representative of the classical liberal political tradition, Tocqueville was an active participant in French politics, first under the July Monarchy (1830–1848) and then during the Second Republic (1849–1851) which succeeded the February 1848 Revolution. He retired from political life after Louis Napoléon Bonaparte's 2 December 1851 coup, and thereafter began work on The Old Regime and the Revolution, Volume I.
Alexis de Tocqueville came from an old Norman aristocratic family with ancestors who participated in the Battle of Hastings in 1066. His parents, Hervé Louis François Jean Bonaventure Clérel, Comte de Tocqueville, an officer of the Constitutional Guard of King Louis XVI, and Louise Madeleine Le Peletier de Rosanbo, narrowly avoided the guillotine due to the fall of Robespierre in 1794. After an exile in England, they returned to France during the reign of Napoleon. Under the Bourbon Restoration, his father became a noble peer and prefect. Tocqueville attended the Lycée Fabert in Metz.
