Libertarianism is a term used by a broad spectrum of political philosophies which seek to maximize individual liberty and minimize or even abolish the state. Libertarians embrace viewpoints across that spectrum ranging from pro-property to anti-property, from minimal government to openly anarchist. The word libertarian is an antonym of authoritarian.
The term libertarian in a metaphysical or philosophical sense was first used by late-Enlightenment free-thinkers to refer to those who believed in free will, as opposed to determinism. Libertarianism in this sense is still encountered in metaphysics in discussions of free will. The first recorded use was in 1789 by William Belsham in a discussion of free will and in opposition to "necessitarian" (or determinist) views.
Metaphysical and philosophical contrasts between philosophies of necessity and libertarianism continued in the early 19th century. The French communist-anarchist Joseph Déjacque was the first to employ the term libertarian in a political sense in May 1857, in an 11-page pamphlet De l'Etre Humain mâle et femelle (Concerning the Human Male and Female), an open letter criticizing Pierre-Joseph Proudhon published while its author was in exile in New Orleans. From 1858 until his return to France in 1861 Déjacque published in New York a journal called Le Libertaire: Journal du Mouvement Social.
According to the anarchist historian Max Nettlau, the first use of the term libertarian communism was in November 1880, when a French anarchist congress employed it to more clearly identify its doctrines. The French anarchist journalist Sébastien Faure, later founder and editor of the four-volume Anarchist Encyclopedia, started the weekly paper Le Libertaire (The Libertarian) in 1895.
