Libertarianism (from French: libertaire, itself from the Latin: libertas, lit. 'freedom') is a political philosophy that upholds liberty as a core value. Libertarians seek to maximize autonomy and political freedom, emphasizing equality before the law and civil rights to freedom of association, freedom of speech, freedom of thought and freedom of choice. Libertarians are often skeptical of or opposed to authority, state power, warfare, militarism and nationalism, but some libertarians diverge on the scope of their opposition to existing economic and political systems. Various schools of libertarian thought offer a range of views regarding the legitimate functions of state and private power. Different categorizations have been used to distinguish various forms of Libertarianism. Scholars distinguish libertarian views on the nature of property and capital, usually along left–right or socialist–capitalist lines. Libertarians of various schools were influenced by liberal ideas.

In the mid-19th century, libertarianism originated as a form of left-wing politics such as anti-authoritarian and anti-state socialists like anarchists, especially social anarchists, but more generally libertarian communists/Marxists and libertarian socialists. These libertarians sought to abolish capitalism and private ownership of the means of production, or else to restrict their purview or effects to usufruct property norms, in favor of common or cooperative ownership and management, viewing private property in the means of production as a barrier to freedom and liberty. While all libertarians support some level of individual rights, left-libertarians differ by supporting an egalitarian redistribution of natural resources. Left-libertarian ideologies include anarchist schools of thought, alongside many other anti-paternalist and New Left schools of thought centered around economic egalitarianism as well as geolibertarianism, green politics, market-oriented left-libertarianism and the Steiner–Vallentyne school. After the fall of the Soviet Union, libertarian socialism grew in popularity and influence as part of anti-war, anti-capitalist and anti- and alter-globalisation movements. (Full article...)
