Libertarianism in the United States in the context of "Anarchy, State, and Utopia"

Civil liberties are fundamental rights and freedoms that governments pledge not to restrict, either through constitutions, legislation, or judicial interpretation, without due process of law. Although the scope of civil liberties differs between countries, they often include the freedom of conscience, freedom of the press, freedom of religion, freedom of expression, freedom of assembly, personal security, personal liberty, freedom of speech, right to privacy, equality before the law, due process of law, the right to a fair trial, and the right to life. Other civil liberties include the right to own property, the right to defend oneself, and the right to bodily integrity. Within the distinctions between civil liberties and other types of liberty, distinctions exist between positive liberty/positive rights and negative liberty/negative rights.

Libertarians advocate for the negative liberty aspect of civil liberties, emphasizing minimal government intervention in both personal and economic affairs. Influential advocates of this interpretation include John Stuart Mill, whose work On Liberty argues for the protection of individual freedoms from government encroachment, and Friedrich Hayek, whose The Road to Serfdom warns against the dangers of expanding state power. Ayn Rand's Atlas Shrugged and Ron Paul's The Revolution: A Manifesto further emphasize the importance of safeguarding personal autonomy and limiting government authority. These contributions have played a significant role in shaping the discourse on civil liberties and the appropriate scope of government.

Libertarian conservatism, also referred to as conservative libertarianism and, more rarely, conservatarianism, is a libertarian political and social philosophy that combines conservatism and libertarianism, representing the libertarian wing of conservatism and vice versa.

Libertarian conservatism advocates the greatest possible economic liberty and the least possible government regulation of social life (described as "small government"), mirroring laissez-faire classical liberalism, but harnesses this to a belief in a more socially conservative philosophy emphasizing authority, morality, and duty. Primarily an American ideology, libertarian conservatism prioritizes liberty, promoting free expression, freedom of choice and free-market capitalism to achieve conservative ends while rejecting liberal social engineering.

American political ideologies conventionally align with the left–right political spectrum, with most Americans identifying as conservative, liberal, or moderate. Contemporary American conservatism includes social conservatism and fiscal conservatism. The former ideology developed as a response to communism and then the civil rights movement, while the latter developed as a response to the New Deal. Modern American liberalism includes cultural liberalism, social liberalism and progressivism, developing during the Progressive Era and the Great Depression. Besides conservatism and liberalism, the United States has a notable libertarian movement, developing during the mid-20th century as a revival of classical liberalism. Historical political movements in the United States have been shaped by ideologies as varied as republicanism, populism, separatism, fascism, socialism, monarchism, and nationalism.

Political ideology in the United States began with the country's formation during the American Revolution, when republicanism challenged the preexisting monarchism that had defined the colonial governments. After the formation of an independent federal government, republicanism split into new ideologies, including classical republicanism, Jeffersonian democracy, and Jacksonian democracy. In the years preceding the American Civil War, abolitionism and secessionism became prominent. Progressivism developed at the beginning of the 20th century, evolving into modern liberalism over the following decades, while modern conservatism developed in response. The Cold War popularized anti-communism and neoconservatism among conservatives, while the civil rights movement popularized support for racial justice among liberals. Populist movements grew in the early-21st century, including progressivism and Trumpism.

Anarcho-capitalism (colloquially: ancap or an-cap) is a political philosophy and economic theory that advocates for the abolition of centralized states in favor of stateless societies where systems of private property are enforced by private agencies. Anarcho-capitalists argue that a society can function without a state through voluntary exchange and private institutions that provide law and security. This would result in a voluntary society based on concepts such as the non-aggression principle, free markets, and self-ownership. In the absence of statute, private defence agencies and/or insurance companies would operate competitively in a market and fulfill the roles of courts and the police, similar to a state apparatus.

According to its proponents, various historical theorists have espoused philosophies similar to anarcho-capitalism. While the earliest existing attestation of "anarchocapitalism" [sic] is in Karl Hess's essay "The Death of Politics" published by Playboy in March 1969, American economist Murray Rothbard was credited with coining the terms anarcho-capitalist and anarcho-capitalism in 1971. A leading figure in the 20th-century American libertarian movement, Rothbard synthesized elements from the Austrian School, classical liberalism and 19th-century American individualist anarchists and mutualists Lysander Spooner and Benjamin Tucker, while rejecting the labour theory of value. Rothbard's anarcho-capitalist society would operate under a mutually agreed-upon "legal code which would be generally accepted, and which the courts would pledge themselves to follow". This legal code would recognize contracts between individuals, private property, self-ownership and tort law in keeping with the non-aggression principle. Unlike a state, enforcement measures in Rothbard’s version of an anarcho-capitalist society would only apply to those who initiated force or fraud. Rothbard views the power of the state as unjustified, arguing that it violates individual rights, reduces prosperity, and creates social and economic problems.

Left-libertarianism, also known as left-wing libertarianism, is a political philosophy and type of libertarianism that stresses both individual freedom and social equality. Left-libertarianism represents several related yet distinct approaches to political and social theory. Its classical usage refers to anti-authoritarian varieties of left-wing politics such as anarchism, especially social anarchism.

While right-libertarianism is widely seen as synonymous with libertarianism in the United States, left-libertarianism is the predominant form of libertarianism in Europe. In the United States, left-libertarianism is the term used for the left wing of the American libertarian movement, including the political positions associated with academic philosophers Hillel Steiner, Philippe Van Parijs, and Peter Vallentyne that combine self-ownership with an egalitarian approach to natural resources. Although libertarianism in the United States has become associated with classical liberalism and minarchism, with right-libertarianism being more known than left-libertarianism, political usage of the term libertarianism until then was associated exclusively with anti-capitalism, libertarian socialism, and social anarchism; in most parts of the world, such an association still predominates.

The Foundation for Rational Economics and Education (FREE) is an American libertarian organization. It was founded in 1976 by U.S. Congressman Ron Paul, who led the organization.

The Tea Party movement was an American fiscally conservative political movement within the Republican Party that began in 2007, catapulted into the mainstream by Congressman Ron Paul's presidential campaign. The movement expanded in response to the policies of Democratic president Barack Obama and was a major factor in the 2010 wave election in which Republicans gained 63 House seats and took control of the U.S. House of Representatives.

Participants in the movement called for lower taxes and for a reduction of the national debt and federal budget deficit through decreased government spending. The movement supported small-government principles and opposed the Affordable Care Act (also known as Obamacare), President Obama's signature health care legislation. The Tea Party movement has been described as both a popular constitutional movement and as an "astroturf movement" purporting to be spontaneous and grassroots, but alleged to have been influenced by outside interests. The movement was composed of a mixture of libertarian, right-wing populist, and conservative activism. It sponsored multiple protests and supported various political candidates since 2009. The movement took its name from the December 1773 Boston Tea Party, a watershed event in the American Revolution, with some movement adherents using Revolutionary era costumes.

Christian libertarianism is the synthesis of Christian beliefs with libertarian political philosophy, with a focus on beliefs about free will, human nature, and God-given inalienable rights.

As with some other forms of libertarianism, Christian libertarianism holds that what is prohibited by law should be limited to various forms of assault, theft and fraud. Other actions that are forbidden by Christianity can only be disciplined by the church, or in the case of children and teens, one's parents or guardians. Likewise, beliefs such as "love your neighbor as yourself" are not imposed on others so long as the non-aggression principle, which Christian libertarians believe to be foundational, has not been violated.
