Copypasta: The Origins of Political Libertarianism i.e. Libertarian Socialism
The first anarchist journal to use the term “libertarian” was La Libertaire, Journal du Mouvement Social. Somewhat ironically, given recent developments in America, it was published in New York between 1858 and 1861 by French communist-anarchist Joseph Déjacque. The next recorded use of the term was in Europe, when “libertarian communism” was used at a French regional anarchist Congress at Le Havre (16–22 November, 1880). January the following year saw a French manifesto issued on “Libertarian or Anarchist Communism.” Finally, 1895 saw leading anarchists Sébastien Faure and Louise Michel publish La Libertaire in France. [Max Nettlau, A Short History of Anarchism, pp. 75–6, p. 145 and p. 162]
In terms of America, we find Benjamin Tucker (a leading individualist anarchist) discussing “libertarian solutions” to land use in February, 1897. As we discuss in section G.3, the Individualist Anarchists attacked capitalist (i.e., right-“libertarian”) property rights in land as the “land monopoly” and looked forward to a time when “the libertarian principle to the tenure of land” was actually applied. [Liberty, no. 350, p. 5]
Interestingly, Rudolf Rocker’s 1949 book, published in Los Angeles, states that individualist anarchist Stephan P. Andrews was “one of the most versatile and significant exponents of libertarian socialism.” [Pioneers of American Freedom, p. 85]
After proclaiming its aim to be “libertarian communism” in 1919, the CNT held its national congress of May 1936 in Zaragoza, with 649 delegates representing 982 unions with a membership of over 550,000. One of the resolutions passed was “The Confederal Conception of Libertarian Communism” [Jose Peirats, The CNT in the Spanish Revolution, vol. 1, pp. 103–10]
…in Britain during the 1960s and 1970s Maurice Brinton and the group he was a member of (Solidarity)) described their politics as “libertarian” and their decentralised, self-managed form of socialism is hard to distinguish from anarchism.
