Political thought

  • c. 1680 →

    Systematic reflection on how societies should be governed. Every ideology below is one answer to a single question: how should power, freedom, and equality be balanced among people?

Liberalism

  • Locke, Smith · 17th–18th c.

    from Political Thought

    The founding liberal creed: individual rights, government by consent, the rule of law, and free markets. Rooted in Locke and Smith, it made liberty and limited government its first principles.

  • T. H. Green, Keynes · c. 1900

    from Classical Liberalism

    Arguing that real freedom needs more than the absence of restraint, social liberals accepted an active state to secure education, health, and welfare — the intellectual basis of the modern mixed economy.

  • Hayek, Nozick · 20th c.

    from Classical Liberalism

    Keeping faith with classical liberalism against the welfare state, libertarians push individual liberty and free markets to the limit, seeking the smallest possible government.

Conservatism

  • Edmund Burke · 1790

    from Political Thought

    Born in Burke's reaction to the French Revolution, conservatism distrusts abstract blueprints, valuing tradition, gradual reform, and the accumulated wisdom of established institutions.

  • Europe · 20th c.

    from Conservatism

    Blending conservative respect for tradition with social concern drawn from Catholic teaching, Christian democracy accepted the welfare state and market economy alike — a centrist force in postwar Europe.

  • USA · late 20th c.

    from Conservatism

    A largely American current that fused free-market economics with a robust, assertive foreign policy and defence of traditional values — conservatism turned outward and interventionist.

Socialism

  • early 19th c.

    from Political Thought

    Reacting to industrial inequality, early socialists like Owen and Saint-Simon called for common ownership and cooperation in place of competition — putting equality at the centre of politics.

  • Karl Marx · 1848

    from Socialism

    Marx recast socialism as a science of history: class struggle drives change, and capitalism's contradictions must give way to a workers' revolution and, ultimately, a classless society.

  • Lenin · 1917

    from Marxism

    Lenin adapted Marxism for a vanguard party to seize power in a still-agrarian Russia, founding the model of the one-party communist state that would spread across the 20th century.

  • Bernstein · c. 1900

    from Socialism

    Bernstein's revisionists broke with revolution, arguing socialism could be won gradually through the ballot box. Social democracy built the welfare state within capitalism rather than overthrowing it.

Nationalism

  • 19th c.

    from Political Thought

    The idea that humanity is divided into nations, each entitled to its own self-governing state. A powerful modern force, it drove both liberation from empires and, in darker forms, exclusion and war.

Anarchism

  • Proudhon, Bakunin · 19th c.

    from Political Thought

    Anarchists reject the state itself as inherently coercive, seeking a society ordered by voluntary cooperation. They split bitterly from Marx over whether any state, even a workers' one, could be trusted.

  • Kropotkin · c. 1880

    from Anarchism

    Kropotkin married anarchism's rejection of the state to common ownership, envisioning stateless communes governed by mutual aid and the principle 'from each according to ability, to each according to need'.

Authoritarian

  • Mussolini, Hitler · 1920s–40s

    from Nationalism

    An extreme, anti-liberal fusion of nationalism with the total state: cult of the leader, glorification of struggle and force, and suppression of the individual beneath the nation or race.

Green & other

  • since 1970s

    from Political Thought

    A newer family placing ecological sustainability at the heart of politics, arguing that environmental limits reshape every question of economy and justice — often paired with grassroots democracy and non-violence.

  • since 19th c.

    from Political Thought

    A movement and body of thought holding that the sexes should be politically, economically, and socially equal, exposing how ostensibly neutral institutions have been built around male power.
