From about the 1920s on, mutualist ideas were relegated to a dwindling remnant of the Tucker group, supplemented by a few oddballs like Albert Nock who couldn't be pigeonholed as orthodox right-libertarians. Mutualists were largely eclipsed by these same right-libertarians, as Mises and his followers, and later Rand and hers, created the various strands of so-called "anarcho-capitalism." At the same time, the libertarian left turned mainly toward anarcho-communism and syndicalism; and its syndicalism was generally of a dogmatic sort that left very little room in its vision of an ideal society for any form of voluntary exchange, or any kind of economic activity not regulated by the syndical federations. As a result, individualism and mutualism were largely irrelevant.

Early New Left, Paul Goodman, Port Huron Statement, Colin Ward, etc.

Revived syndicalism, critique of business unionism, Root and Branch, IWW, "wildcat" movement of '70s, etc.

Rothbard Hess project of alliance btw libertarian left and right; SEK3's Movement of the Libertarian Left. Jesse Walker quote, analogy to de Cleyre.

Back to land movement, human scale/alternative tech, Schumacher, Kirk Sale, revival of deliberate theoretical components of cooperative movement, etc.

Theories of dual power, counter-power, prefigurative politics, etc.

Contemporary mutualist organizations, including member organizations of vcm and associated organizations, Cooperative Party, etc. There are quite a few organizations today that promote mutualist ideas. Although generally small and relatively obscure, they produce solid work and have stable audiences and constituencies.
