Far-Left Extremist Groups in the United States

By The Counter Extremism Project

Far-left extremism in the United States largely centers around the notion of correcting an injustice but is otherwise broad in its ideological catchment. In the 20th century, U.S. left-wing extremism was synonymous with either communism or causes such as environmentalism. In the 1960s and ’70s, the Weather Underground declared war against the U.S. government and carried out a campaign of political violence.* According to the FBI, far-left extremism in the United States was most active during the period between the 1960s and 1980s. Special-interest extremism began to emerge on the far-left in the 1990s, resulting in the promulgation of groups such as the Animal Liberation Front (ALF) and Earth Liberation Front (ELF). The FBI estimated that between 1996 and 2002, these two groups were responsible for 600 criminal acts in the United States that caused more than $42 million in damages.*

Throughout the 1990s and early 2000s, ALF and ELF targeted animal research facilities and corporations for acts of vandalism and destruction of property. After the September 11, 2001, terrorist attacks, the U.S. government reevaluated how it approached terrorism abroad and at home. While the government focused on al-Qaeda as the primary foreign threat, federal authorities—partly in response to government lobbying by corporations victimized by ecoterrorists—considered ALF and ELF to be the primary domestic terrorism threat in what media dubbed the Green Scare.* By 2010, however, federal authorities had shifted their domestic focus to the threat of the far right, which continued to overshadow the radical far left in violent attacks while ALF and ELF focused on property damage.* A July 2020 report by the Center for Strategic and International Studies (CSIS) reviewed almost 900 politically motivated attacks since 1994. Researchers found that far-left attacks had resulted in only one fatality in that 25-year span, compared with 329 fatalities in attacks by the far right.* In recent years, however, the radical far left has seen a resurgence in response to the rise of the far right, particularly since the 2017 Unite the Right rally in Charlottesville, Virginia, when far-right protesters clashed with far-left counter-protesters. A revitalized American far left has emerged to lead protest movements against the far right and perceived injustices. Armed groups such as the John Brown Gun Club formed to directly confront the violent far right and a broad interpretation of fascism, which often include symbols of capitalism and corporations. These manifestations have been on display during 2020 protests against police brutality, during which the far left have become increasingly visible and destructive, leading then-President Donald Trump in May 2020 to call for designating the broad anti-fascist ideology Antifa a terrorist organization.*
