CrimethInc.

Emerged in the mid-1990s, initially as the hardcore zine Inside Front, and began operating as a collective in 1996. It has since published widely read articles and zines for the anarchist movement and distributed posters and books of its own publication. CrimethInc. Cells have published books, released records, and organized national campaigns against globalization and representative democracy in favor of radical community organizing. Less public splinter groups have carried out direct action (including arson and hacktivism), hosted international conventions and other events, maintained local chapters, sparked riots, and toured with multimedia performance art or anarcho-punk musical ensembles. The collective has received national media and academic attention, as well as criticism and praise from other anarchists for its activities and philosophy. CrimethInc. Has an association with the North American anarcho-punk scene due to its relationship with artists in the genre and its publishing of Inside Front as well as more recently the contemporary anti-capitalist movement.

Activities by CrimethInc. cells have toured with hardcore anarcho-punk musical ensembles. In 2002, a cell in Olympia, Washington, staged a five-day film festival with skill-sharing workshops and screenings. Cells have also supported various large-scale campaigns with publicity work, including "Unabomber for President" and the "Don't Just (Not) Vote" election campaigns as well as the protests against the Free Trade Area of the Americas of 2003 in Miami, Florida. Individuals adopting the CrimethInc. nom de guerre have included convicted Earth Liberation Front arsonists, as well as hacktivists who successfully attacked the websites of DARE, the Republican National Committee, and sites related to U.S. President George W. Bush's 2004 re-election campaign. These activities have earned the collective irregular attention from the mainstream news media. Several CrimethInc. cells have worked in collaboration with other anti-capitalists and anarchists to promote Steal Something From Work Day every April 15, which coincides with the United States Tax Day, to protest exploitation in the workplace.

Since the summer of 2002, CrimethInc. has hosted annual conventions, termed "convergences", open to anyone. Typically featuring the performances of traveling theatrical troupes, musicians, direct-action and mutual-aid workshops from individual participants, the few-days-long camping trips have attracted coverage in newspaper articles, initiated multiple Reclaim the Streets actions, mobilized large Critical Mass events, and catalyzed many other activities. The 2007 convergence in Athens, Ohio, saw an impromptu street party which resulted in arrests on minor charges. The Athens News characterized the convergence as "a sort of networking, resume-swapping opportunity for would-be radicals, free-thinkers, Levellers, Diggers, Neo-Luddites, and other assorted malcontents." It is typical of these gatherings to require that all attendees have something to contribute to the momentum: whether it is bringing food or equipment to share, leading a discussion group, or providing materials with which to write to political prisoners. There has been a pattern of promoting convergences as festivals, reminiscent of barnstorming flying circuses and travelling sideshows. Harper's journalist Matthew Power described the 2006 convergence in Winona, Minnesota, as follows: Several hundred young anarchists from around the country had train-hopped and hitchhiked there to attend the annual event known as the CrimethInc Convergence...Grimy and feral-looking, the CrimethInc kids squatted in small groups around a clearing...[they] were in the middle of several days of self-organized workshops, seminars, and discussions, ranging from the mutualist banking theories of the nineteenth-century anarchist philosopher Pierre-Joseph Proudhon, to an introductory practicum on lock-picking, to a class on making one's own menstrual pads... CrimethInc's adherents had come together there because they wanted to live their lives as some sort of solution. They saw 'the revolution' not as a final product but as an ongoing process; they wanted not just to destroy the capitalist system but to create something livable in its place. These convergences have been hosted by different groups within the collective each time, typically based on the initiative of local enthusiasts. Every year a different set of policy requests is released from locals in the field, typically encouraging a sober, consensus-based space in which no financial transactions are made. The one firm rule has been "No police informants", a regulation which has been ignored by the FBI. Information gathered by FBI informants at CrimethInc. convergences (in 2004, 2005, and 2008) contributed to the convictions of Eric McDavid and his associates, as well as 2008 Republican National Convention protester Matthew DePalma. In 2010, CrimethInc. announced the We Are Everywhere campaign of national tours and events in lieu of the traditional convergence. In 2015, CrimethInc. embarked on the similar To Change Everything two-month tour of the United States.

CrimethInc. is associated with the North American anarcho-punk scene because of its long relationship with notable musicians in the genre and its publishing of Inside Front, a "journal of hardcore punk and anarchist action". CrimethInc. releases include LP's, CD's, and 7-inch vinyl records from North American and European anarcho-punk, hardcore, and anti-folk bands, including Catharsis, Zegota, Requiem, and From the Depths. Academic Stacy Thompson has described CrimethInc. as "exemplary of a more contemporary and nuanced approach" to the possible forms anarcho-punk could take to resist commodification through aesthetic expression. However, Thompson does not consider the aesthetic choices of the collective to be substantially different from the anarcho- and crust punk bands released by fellow anarcho-punk collective Profane Existence in the mid-to-late 90s.
