Antifa–short for “anti-fascist” or “Anti-Fascist action”–is a decentralized left-wing extremist movement that opposes, sometimes through violence, groups it considers “fascist,” including democratic, center-right conservatives.1234 Antifa lacks a known organizational structure3 or an official leader or headquarters, though individual groups in certain states reportedly hold regular meetings.5 Anyone can claim the title and set up a local branch.3

The term Antifa is currently used to define a broad group of people whose political beliefs lean toward the left, often the extreme left, who engage in aggressive protests against right-wing and center-right political groups.6 Antifa’s protest methods are often violent, and local leaders admit they’re willing to physically attack anyone who employs violence against them or who “condones racism,” as the Antifa demonstrators define it.7
Antifa has reportedly grown rapidly8 and has become more active in the wake of Donald Trump’s 2016 Presidential campaign.9 This surge of activity has been markedly more violent than traditional political protest movements.10 Though some decry their use of violence as a means of protest, Antifa’s tactics have recently “elicited substantial support from the mainstream left.”8
Antifa claim inspiration from 1930s-era extreme-left-wing German street protesters opposed to the rising Nazi regime.3 Modern “black bloc” Antifa resurfaced in the 1980s, again allegedly to oppose neo-fascist skinhead movements.3
The movement first entered the American stage as Anti-Racist Action, a network that originated in 1987 with the “Baldies,” an organization in Minneapolis, leading to the creation of other groups across the country to fight neo-Nazis.3 After a relatively dormant period, large numbers of Antifa activists appeared in the United States at anti-World Trade Organization protests in 1999 in Seattle, and then more recently during the Occupy Wall Street movement. 11 Donald Trump’s success in the 2016 campaign and resulting Presidency has seen “explosive growth” in Antifa membership and a surge in violent activity.8
Antifa’s lack of centralized structure make it difficult to calculate the movement’s size and membership.12 While groups that claim to align with the Antifa movement exist, such as the Rose City Antifa in Portland and the Atlanta Antifascists in Atlanta, these groups typically lack an organizational structure and are not beholden to guidelines of a larger group or individual. 13 Antifa chapters that do exist organize mostly on message boards such as Reddit and over social networks like X (formerly Twitter)and Facebook.14
Similarly, Antifa’s decentralized character makes it difficult to pin down what exactly it is they oppose. 3 Moreover, this lack of national organization, combined with the group’s secrecy and cloak of anonymity, make the group effectively “impossible to track.”7
The Torch Network is a loosely connected network of groups aligned with Antifa beliefs. As of October 2025, the network consisted of 8 chapters across the United States, and five chapters that no longer exist or are no longer active. According to the Torch Network, chapters are “autonomous organizing bodies” that are aligned with the network’s “points of unity.” 15 These points are as follows: 16
As of October 2025, the groups aligned with the Torch Network include: 15
Asheville Anti Racism
Rose City Antifa
Atlanta Antifascists
Central Texas Anti-Racist Action
CVAntifa
Bay 161
Front Range Anti-Fascists
Chicago Anti-Fascist Action
The Torch Network’s Website includes methods of contact for each of the aligned groups, including X (formerly Twitter) pages, emails, Facebook pages, or in some cases a Mastodon page, an open-source decentralized social networking site. 15
On October 14, 2025, journalist Andy Ngo posted on X, formerly Twitter, that the Antifa Torch Network had previously hosted a conference in Denver, Colorado, held on November 11 and 12, 2016, to discuss “the network and upcoming goals/strategies” following President Trump’s victory in the 2016 presidential election. According to the post and attached images by Ngo, local chapters and other affiliated groups that took part included “Rocky Mountain Antifa, Philly Antifa, WNC Antifa, Los Angeles People Against Racist Terror (PART)/ARA-LA, and South Side Chicago ARA.” 17
Antifa International acts as an unofficial hub for the promotion of antifa aligned ideology as well as relevant news related to the movement. Antifa International has accounts on Instagram, Facebook, BlueSky, Substack, and YouTube. 18
In 2015, Antifa International launched the International Anti-Fascist Defence Fund, which was created to “provide immediate support” to people involved in the Antifa movement who may be facing legal, financial, or other difficulties as a result of their activism. Whether or not the fund allocates it’s money to someone is based off of a mutual decision by the donors of the fund, whether by consensus or majority vote. 19
In late September of 2025, in response to the designation of Antifa as a domestic terrorist organization by the Trump administration, the fund closed it’s donation framework in order to “protect [their] donors and recipients.” 20
While the decentralized nature of Antifa makes it difficult to identify how they operate, an excerpt from a widely disseminated guide for new Antifa organizations published by It’s Going Down describes Antifa operations and expectations Antifa members are obliged to meet.21
Antifa’s “obligations” include:
Additionally the Antifa guide lays out a number of other suggestions/best practices including:
The anti-fascist movement has come from multiple theoretical currents; Antifa is based on an agreement on tactics — not ideological uniformity. In the U.S., most activists are anarchist, although a few are Maoist or anti-state Marxists. (In other countries, the movement is predominately Marxist.)11
Antifa groups have one unifying feature, “tracking and countering fascists and white supremacists.” 11 Otherwise, the lack of hierarchy means that each local Antifa chapter decides what causes they choose to fight against. 11 These include, but are by no means limited to:
The Antifa organizing guide states, “Antifascism is not a stand-alone ideology; it is a piece of a whole.”11 Antifa operations are therefore seen as “a certain set of practices within the broader radical movement against white supremacy… hierarchy and oppression in general.”11 As such, Antifa members are encouraged to organize mass demonstrations against opponents with allied groups who are willing to work with them or to join demonstrations by other groups such as Black Lives Matter or for immigrants and refugees, all the while carrying antifa flags and banners.11
Yet again the decentralized nature of Antifa allows each individual chapter to decide what other “radical movements” they choose to align themselves with.22 These include, but are by no means limited to:
Antifa groups often directly advocate violence and “don’t apologize” when violence breaks out at their rallies.22 “Their methods are often violent and Antifa leaders admit they’re willing to physically attack anyone who employs violence against them or who condones racism – as long as force is used in the name of eradicating hatred.”24 As one Antifa leader explained, “You have to put your body in the way… and you have to make it speak in the language that they understand. And sometimes that is violence.”24
Antifascists rationalize their violent actions as “defensive.” They argue, “Hate speech against vulnerable minorities… leads to violence against vulnerable minorities.”8
Far-right provocateur Milo Yiannopoulos was scheduled to speak at the University of California Berkeley’s campus at a university-approved event.25 More than 1,000 protesters were outside the UC Berkeley venue where Yiannopoulos planned to speak when a group of “about 150” black-clad, masked Antifa stormed the police barricades that kept protesters away from the entrances.26 The university said that the “150 masked agitators” responsible for the unrest “had come to campus to disturb an otherwise peaceful protest.”27
These black-clad protesters wearing masks threw Molotov cocktails and smashed windows at the Martin Luther King, Jr. student union center where the Yiannopoulos event was to be held, which caused several fires to break out.2 They smashed windows of local banks. They set fires near the campus bookstore and damaged the construction site of a new dorm.10 Violent Antifa even pepper-sprayed a woman while she was being interviewed on live television – just because she was wearing a red “Make America Great Again” hat.27
Ultimately six people had to be treated for injuries suffered during the riot.25 Administrators decided to cancel the event about two hours before Yiannopoulos was to speak. UC Berkeley said it removed him from campus “amid the violence and destruction of property and out of concern for public safety.”27
On January 20, 2017, the day of President Trump’s inauguration, more than 200 protestors formed a “black bloc” in which members wearing black or dark clothes and other riot gear armed with hammers, crowbars, wooden sticks, and other weapons marched through downtown Washington, D.C., and “within minutes” began vandalizing public and private property.28 They smashed storefront windows, trashed the streets, confronted peaceful inauguration and parade attendees, lit a limousine on fire,9 and set several other fires across the downtown area.29
At one point the group of more than 200 participants charged at a police line and approximately 50 individuals broke through, some of whom continued to engage in violence. In one detailed court account, Dane Powell admitted that he and others threw approximately 16 bricks, rocks, or pieces of concrete at uniformed officers, one of whom was knocked unconscious.30
More than 230 people were arrested in the aftermath of the incidents on January 20, 2017, with 21 of those arrested pleading guilty to charges of violent protest. 31 Powell was the first to plead guilty to felony charges, including rioting and assaulting a police officer. 31 He was among 212 defendants named in a superseding indictment, all charged with felonies.30 Powell was sentenced to 4 months imprisonment and was subsequently released in October 2017. 31
Despite wielding weapons, damaging property, and lighting a limousine on fire, some members of the group thought that there was not enough violence. “I think there should have been more violence yesterday … there were some rocks thrown … the police stopped me,” said Tom Massey of Philadelphia.9
In January 2018, federal prosecutors dismissed the cases of over 100 defendants arrested the previous year, with at least 10 additional cases being dropped in May 2018 when District of Columbia Superior Court ruled that prosecutors had withheld evidence. 31 By July 2018, the remaining charges against 38 defendants awaiting trial were dropped, with then-U.S Attorney for the District of Columbia Jessie K. Liu announcing “after further review, the United States, in the exercise of its discretion, has determined that these matters should be dismissed without prejudice.” 31 Freelance journalist Aaron Cantú, one of the 38 defendants, was the last of nine journalists arrested in January 2017 to have charges dropped. 31
In Portland, Oregon, Antifa has been involved in various protests ending in violence. 24 In May 2017, 25 anarchists were arrested in Portland for rioting, random acts of vandalism to public and private property, and for throwing incendiary devices, including fireworks and Molotov cocktails, at police.32
Then in August, police in Portland again geared up for the tenth protest since Election Day involving extremist nationalist and extreme-left street demonstrators.24 In the days leading up to the planned protests, the Portland police said they “saw on social media that there was a lot of threats being put back and forth” that caused “concern about physical violence.” The police created a human barricade, with officers standing shoulder to shoulder between two city squares — one filled with extremist nationalist groups, the other with Antifa activists. That strategy worked for a few hours, but police caught word that Antifa members were planning to push past police into the opposing extremists’ rally square.24
Police gathered the masked Antifa activists and detained them. In the process, they seized a large number of weapons from Antifa protestors that day.24 “Everything from knives to brass knuckles to poles and sticks and bricks and bottles and road flares and chains.” According to Portland’s Police Spokesmen, “One hundred percent, they came geared up to fight if it would be allowed.”24
In September 2025, the Trump administration issued an executive order formally designating Antifa as a domestic terrorist organization. The order described Antifa as a “militarist, anarchist enterprise” 33 engaged in political violence, doxing, assaults on federal law enforcement, and organized riots with the aim of obstructing the rule of law. It directed federal agencies to investigate, disrupt, and dismantle Antifa-associated networks, emphasizing prosecutorial action against individuals or groups accused of providing material support. 33
Following the order, the Department of Homeland Security (DHS), under Secretary Kristi Noem, announced a series of arrests of individuals described as Antifa-aligned violent extremists. DHS reported that these arrests were tied to incidents including assaults on Immigration and Customs Enforcement (ICE) officers, bomb threats against federal facilities, and armed ambushes on detention centers. Federal officials framed these actions as part of a broader campaign to protect law enforcement and counter what they described as a wave of Antifa-linked political violence. 34
The designation was notable in part because, at the time of it’s release, U.S. law does not provide a clear mechanism for domestic groups to be classified as terrorist organizations in the same way that foreign entities are. As a result, the move generated debate over its legal basis, scope, and potential implications for civil liberties and political dissent. 35
In March 2026, nine alleged members of what the U.S. Department of Justice described as a “North Texas Antifa Cell” were convicted in federal court on charges stemming from a July 4, 2025 attack upon U.S. Immigration and Customs Enforcement’s Prairieland Detention Facility in Alvarado, Texas. In addition to setting off fireworks and engaging in vandalism, one of the defendants was accused of having fired a shot which wounded a responding Alvarado police officer in the neck.36
According to the Justice Department, “testimony and other evidence at trial established that the defendants were members of a North Texas Antifa Cell, part of a larger militant enterprise made up of networks of individuals and small groups primarily ascribing to an ideology that explicitly calls for the overthrow of the United States Government, law enforcement authorities, and the system of law.”36 The trial was the first instance in which individuals alleged to have been members of Antifa were convicted on domestic terrorism charges. The defendants’ attorneys argued that their clients were not Antifa members, and multiple cooperating witnesses testified that they did not view themselves as being part of Antifa.37
Eight of the defendants were convicted on rioting and explosives charges, in addition to providing material support to terrorists. One of them, Benjamin Song, was also convicted of attempted murder for firing the shot that wounded the police officer. Prior to the trial, seven other defendants had pleaded guilty to one count of providing material support to terrorists.36 In total, nineteen individuals were charged in connection with the attack.38
