The Palmer Raids were a series of raids conducted in November 1919 and January 1920 by the United States Department of Justice under the administration of President Woodrow Wilson to capture and arrest suspected socialists, especially anarchists and communists, and deport them from the United States. The raids particularly targeted Italian immigrants and Eastern European Jewish immigrants with alleged leftist ties, with particular focus on Italian anarchists and immigrant leftist labor activists. The raids and arrests occurred under the leadership of Attorney General A. Mitchell Palmer, with 6,000 people arrested across 36 cities. Though 556 foreign citizens were deported, including a number of prominent leftist leaders, Palmer's efforts were largely frustrated by officials at the U.S. Department of Labor, which had authority for deportations and objected to Palmer's methods.
Anarchism and violence have been linked together by events in anarchist history such as violent revolution, terrorism, and assassination attempts. Leading late 19th century anarchists espoused propaganda by deed, or attentáts, and was associated with a number of incidents of political violence. Anarchist thought, however, is quite diverse on the question of violence. Where some anarchists have opposed coercive means on the basis of coherence, others have supported acts of violent revolution as a path toward anarchy. Anarcho-pacifism is a school of thought within anarchism which rejects all violence.
Nicola Sacco and Bartolomeo Vanzetti were Italian immigrants and anarchists who were controversially convicted of murdering Alessandro Berardelli and Frederick Parmenter, a guard and a paymaster, during the April 15, 1920, armed robbery of the Slater and Morrill Shoe Company in Braintree, Massachusetts, United States. Seven years later, they were executed in the electric chair at Charlestown State Prison.
Propaganda of the deed is specific political direct action meant to be exemplary to others and serve as a catalyst for revolution.
The Wall Street bombing was an act of terrorism on Wall Street at 12:01 pm on Thursday, September 16, 1920. The blast killed 30 people immediately, and another 10 later died of wounds that they sustained in the blast. There were 143 seriously injured, and the total number of injured was in the hundreds.
The first Red Scare was a period during the early 20th-century history of the United States marked by a widespread fear of far-left movements, including Bolshevism and anarchism, due to real and imagined events; real events included the Russian 1917 October Revolution, German Revolution of 1918–1919, and anarchist bombings in the U.S. At its height in 1919–1920, concerns over the effects of radical political agitation in American society and the alleged spread of socialism, communism, and anarchism in the American labor movement fueled a general sense of concern.
Luigi Galleani was an Italian insurrectionary anarchist best known for his advocacy of "propaganda of the deed", a strategy of political assassinations and violent attacks.
Thomas William Hardwick was an American politician from the U.S. state of Georgia who served as governor of Georgia, a United States Senator from Georgia, a member of the United States House of Representatives from Georgia, and a member of the Georgia House of Representatives.
The Preparedness Day bombing was a bombing in San Francisco, California, United States, on July 22, 1916, of a parade organised by local supporters of the Preparedness Movement which advocated American entry into World War I. During the parade a suitcase bomb was detonated, killing 10 and wounding 40 in the worst terrorist attack in San Francisco's history.
The Lexington Avenue explosion was the July 4, 1914, explosion of a terrorist bomb in an apartment at 1626 Lexington Avenue in New York City. Members of the Lettish section of the Anarchist Black Cross (ABC) were constructing a bomb in a seven-story tenement when the group's large supply of dynamite exploded prematurely. The blast destroyed most of the top three floors of the building, killing three conspirators and another renter who was not part of the bomb plot, as well as injuring dozens more.
Webster Thayer was a judge of the Superior Court of Massachusetts, best known as the trial judge in the Sacco and Vanzetti case.
Mario Buda (1883–1963) was an Italian anarchist who was active among the militant American Galleanists in the late 1910s and best known for being the likely perpetrator of the 1920 Wall Street bombing, which killed 40 people and injured hundreds. Historians implicate Buda in multiple bombings, though the documentary evidence is insufficient to prove his responsibility.
The Immigration Act of 1903, also called the Anarchist Exclusion Act, was a law of the United States regulating immigration. It codified previous immigration law, and added four inadmissible classes: anarchists, people with epilepsy, beggars, and importers of prostitutes. It had minimal impact and its provisions related to anarchists were expanded in the Immigration Act of 1918.
The United States Immigration Act of 1918 was enacted on October 16, 1918. It is also known as the Dillingham-Hardwick Act. It was intended to correct what President Woodrow Wilson's administration considered to be deficiencies in previous laws, in order to enable the government to deport undesirable aliens, specifically anarchists, communists, labor organizers, and similar activists.
The Milwaukee Police Department bombing was a November 24, 1917, bomb attack that killed nine members of local law enforcement and a civilian in Milwaukee, Wisconsin. The perpetrators were never caught but are suspected to be an anarchist terrorist cell operating in the United States in the early 20th century. The target was initially an evangelical church in the Third Ward and only killed the police officers when the bomb was taken to the police station by a concerned civilian. The bombing remained the most fatal single event in national law enforcement history for over 80 years until the September 11 attacks.
The Bresci Circle was a group of New York City anarchists who are remembered for a failed bombing attempt on St. Patrick's Cathedral in 1915, in which two of its members were arrested. The group was named after Gaetano Bresci, a New York anarchist who killed King Umberto I of Italy.
La Salute è in voi! was an early 1900s bomb-making handbook associated with the Italian-American Galleanisti, followers of anarchist Luigi Galleani. The anonymous authors advised impoverished workers to overcome their despair and commit to individual, revolutionary acts. The Italian-language handbook offered plain directions to give non-technical amateurs the means to build explosives. Though this technical content was already available in encyclopedias, applied chemistry books, and industrial sources, La Salute è in voi wrapped this content within a political manifesto. Its contents included a glossary, basic chemistry training, and safety procedures. Its authors were likely Galleani and his friend Ettore Molinari, a chemist and anarchist.
Galleanisti are followers or supporters of the insurrectionary anarchist Luigi Galleani, who operated most notably in the United States following his immigration to the country. The vast majority of Galleanisti or Galleanists were similarly poor and working-class Italian immigrants or Italian Americans, especially anarchists and those involved in the labor movement. Galleanists remain the primary suspects in a campaign of bombings between 1914 and 1920 in the United States.
Carlo Valdinoci was an Italian Galleanist anarchist based in the United States and the publisher of Luigi Galleani's Cronaca Sovversiva. He is believed to have been involved in multiple Galleanist plots.
The Youngstown dynamite plot was a foiled attempt by Galleanist anarchists to move a case of dynamite by train from Steubenville, Ohio, to Chicago, from January 17–18, 1918. The 18-year-old Gabriella "Ella" Antolini Segata, part of the Italian Galleanist circle, was caught by a suspicious train porter. The dynamite was potentially en route to Milwaukee, where anarchists had been squaring off with police in a series of counter-retaliatory attacks stemming from the September 1917 Bay View incident. Antolini Segata was imprisoned for 18 months and the case was a big break for the Bureau of Investigation agent Rayme Weston Finch, who would come to lead investigations against the Galleanists.
