writer Dean Russell, a colleague of Leonard Read and a classical liberal himself. Russell justified the choice of the term as follows: Subsequently, a growing number of Americans with classical liberal beliefs began to describe themselves as libertarians. One person responsible for popularizing the term libertarian in this sense was Murray Rothbard, who started publishing libertarian works in the 1960s. Rothbard described this modern use of the words overtly as a "capture" from his enemies, writing that "for the first time in my memory, we, 'our side,' had captured a crucial word from the enemy. 'Libertarians' had long been simply a polite word for left-wing anarchists, that is for anti-private property anarchists, either of the communist or syndicalist variety. But now we had taken it over". In the 1970s, Robert Nozick was responsible for popularizing this usage of the term in academic and philosophical circles outside the United States,<ref>Teles, Steven; Kenney, Daniel A. (2008).

In the book, Nozick proposed a minimal state on the grounds that it was an inevitable phenomenon which could arise without violating individual rights. According to common United States meanings of conservative and liberal, libertarianism in the United States has been described as conservative on economic issues (economic liberalism and fiscal conservatism) and liberal on personal freedom (civil libertarianism and cultural liberalism). It is also often associated with a foreign policy of non-interventionism.Edward A. Olsen (2002). US National Defense for the Twenty-First Century: The Grand Exit Strategy. Taylor & Francis. p. 182 . . Definition Although libertarianism originated as a form of left-wing politics, the development in the mid-20th century of modern libertarianism in the United States resulted in libertarianism being commonly associated with right-wing politics. It also resulted in several authors and political scientists using two or more categorizations to distinguish libertarian views on the nature of property and capital, usually along left–right or socialist–capitalist lines. Right-libertarians reject the label due to its association with conservatism and right-wing politics, calling themselves simply libertarians, while proponents of free-market anti-capitalism in the United States consciously label themselves
