The Palmer Raids. The founding act of federal political policing in the United States, and the twenty-four-year-old who ran it.
Between November 1919 and January 1920, the Justice Department arrested at least three thousand people without warrants, deported more than five hundred, and did it through a new office run by J. Edgar Hoover. The record is not disputed. Palmer wrote it down himself.
Attorney General A. Mitchell Palmer created the General Intelligence Division inside the Bureau of Investigation on August 1, 1919, and put twenty-four-year-old Special Assistant J. Edgar Hoover in charge of it. Between November 7, 1919 and January 2, 1920, that office coordinated mass warrantless arrests of suspected radicals across more than thirty cities. Hundreds were deported without a court hearing. Palmer defended the operation in a signed report to the U.S. Senate on November 14, 1919; that report is a primary source, still on file. The office he created outlived him. The man he hired ran the FBI for the next fifty-three years.
Primary sources include Palmer’s November 14, 1919 report to the U.S. Senate, the DOJ Inspector General’s reconstruction in the 1976 Levi Guidelines review, and Selden’s academic reconstruction of Hoover’s GID role.
What this page is about
The Palmer Raids were a coordinated federal operation, November 1919 through January 1920, that produced at least 3,000 warrantless arrests across more than 30 cities and roughly 556 deportations conducted without judicial hearings. The operation was managed by a newly-created office inside the Bureau of Investigation — the General Intelligence Division, run by a 24-year-old J. Edgar Hoover — whose defining product was a card file of political affiliations that reached roughly 200,000 names by 1921.
This page treats the Palmer Raids as the founding operation of the modern federal political-intelligence apparatus. Not because the word “COINTELPRO” existed in 1919 — it did not — but because the operational logic (break movements through mass disruption rather than individual prosecution) and the institutional infrastructure (a permanent domestic-radical index inside the Bureau) began here and continued forward. The DOJ’s own 1976 Inspector General review of the Levi Guidelines identifies the 1919 GID as the direct predecessor of the FBI’s domestic-intelligence operations the guidelines were designed to constrain.
Every claim on this page is graded. Load-bearing citations are Palmer’s own November 14, 1919 report to the Senate, the May 28, 1920 Report Upon the Illegal Practices of the United States Department of Justice by twelve prominent lawyers, Judge George W. Anderson’s June 23, 1920 opinion in Colyer v. Skeffington, and the DOJ Inspector General’s 1976 reconstruction of the GID for the Levi Guidelines review.
The word “COINTELPRO” did not exist in 1919. This piece traces continuity of method and institution, not a formally-named program.
We are not alleging any single actor named below acted illegally by 1919 standards. We document what happened, what it produced, and how the operational lineage runs forward.
The Palmer Raids were not an aberration. They were the founding act of federal political policing, run by the office that would become the FBI, and their operational logic ran for the next fifty years.
Two things about November 1919 are worth holding together. First: the raids happened openly. Palmer signed the November 14, 1919 report to the Senate defending the arrests as necessary counter- revolutionary work; he was not concealing them. Second: the office he created to run them — the General Intelligence Division inside the Bureau of Investigation — did not close after the panic passed. Its twenty-four-year-old chief, J. Edgar Hoover, kept the card file. The card file became the template. The template became COINTELPRO. The lineage is not a rhetorical claim: it is a paper trail that runs from the November 1919 Senate report through the 1976 Levi Guidelines review by the DOJ’s own Inspector General.
The 1920 report signed by twelve prominent American lawyers — including future Supreme Court Justice Felix Frankfurter and Harvard Law dean Roscoe Pound — documented specific illegality in real time: warrantless entries, denial of counsel, torture- adjacent detention conditions, and coerced statements. It is a contemporary judicial record, not a later reconstruction. And it was ignored.
June 1917 to November 1976: from the Espionage Act to the DOJ’s own reconstruction of what Palmer built.
The dates below are the anchor points every other section of this page references. Every claim in §5, every personnel entry in §4, and every “record versus narrative” note in §6 ties back to a date on this list.
- June 15, 1917Congress passes the Espionage Act.
The statutory infrastructure for prosecuting political speech during and after World War I is put in place. Amended in May 1918 (the Sedition Act) to criminalize criticism of the government, the flag, or the military. Both statutes remain the constitutional predicate for what follows.
- March 5, 1919A. Mitchell Palmer is sworn in as U.S. Attorney General.
Wilson appointee. Quaker. Previously a three-term congressman from Pennsylvania. Enters office with the war concluded and domestic labor unrest at record levels.
- April 28 – May 1, 1919The mail bombs.
Between April 28 and May 1, roughly thirty-six mail bombs are sent to prominent Americans including Palmer, Justice Oliver Wendell Holmes Jr., John D. Rockefeller, and multiple senators. Most are intercepted; a maid at a Georgia senator’s home is injured. On June 2, a second wave detonates near-simultaneously in eight cities; one explodes on Palmer’s own Washington doorstep, killing the bomber (later identified as Italian anarchist Carlo Valdinoci). Palmer’s house is destroyed.
- August 1, 1919Palmer creates the General Intelligence Division inside the Bureau of Investigation and appoints J. Edgar Hoover to run it.
Hoover is twenty-four years old. He has been at the Justice Department since July 1917, initially working on enemy-alien registration during the war. The GID’s explicit mission is to compile intelligence on domestic radicalism. Within eighteen months, Hoover’s card file will contain roughly 200,000 names.
- November 7, 1919First Palmer Raid: the Union of Russian Workers arrests.
Bureau agents and local police in twelve cities arrest at least a thousand people identified as members of the Union of Russian Workers. Warrants are secured in some cases and not in others. In New York, the raid on the Russian People’s House at 133 East 15th Street becomes the operation’s prototype: forced entry, mass roundup of everyone present, injuries reported to detainees, and hearings conducted in Bureau custody rather than before an immigration judge.
- November 14, 1919Palmer submits his report to the U.S. Senate.
The signed report is the operation’s primary defense document — and one of the most valuable sources on the raids because Palmer describes what his department did in his own words. He identifies the GID as the intelligence organ, names the Union of Russian Workers as the primary target, and defends the methodology on the ground that revolutionary organizations cannot be treated the way conventional criminal defendants are.
- December 21, 1919The Buford sails. 249 deportees, most without hearings.
The transport ship USAT Buford, nicknamed the “Soviet Ark” in the press, leaves New York carrying 249 deportees to Soviet Russia. Emma Goldman and Alexander Berkman are aboard. Most of the deportees have not had individual immigration hearings; the deportations were processed en masse under wartime authority Congress had not formally revoked.
- January 2, 1920Second Palmer Raid: coordinated arrests in 30+ cities in one night.
Between three thousand and ten thousand people are arrested nationwide in a single coordinated operation targeting Communist Party USA and Communist Labor Party membership. Bureau agents enter meeting halls, homes, restaurants, and pool rooms without warrants in a substantial fraction of the cases. Louis Freeland Post, Assistant Secretary of Labor, will later personally review roughly six thousand of the deportation orders and cancel most of them.
- May 28, 1920Twelve lawyers publish Report Upon the Illegal Practices of the United States Department of Justice.
A group including Felix Frankfurter (later Supreme Court Justice), Roscoe Pound (Dean, Harvard Law School), Zechariah Chafee Jr., Ernst Freund, and Frank P. Walsh signs the report. It documents warrantless entries, prolonged incommunicado detention, denial of counsel, physical mistreatment of detainees, and coerced statements — with specific case files. The report is submitted to Congress and published nationally.
- May 1920Assistant Secretary of Labor Louis F. Post cancels 1,500+ deportation orders.
Reviewing the cases individually against the evidentiary standard the deportation statute actually required, Post cancels roughly 71 percent of the pending deportation warrants against arrested radicals. Palmer demands Post’s impeachment; Congress declines to pursue it after House hearings expose the underlying evidentiary weakness of most cases.
- June 1, 1920Judge George W. Anderson rules the Boston raids unconstitutional in Colyer v. Skeffington.
Federal District Judge George W. Anderson, in a Boston habeas case reviewing the January raid there, issues one of the era’s strongest judicial rejections: he calls the Bureau’s tactics “shocking to conscience” and orders roughly twenty detainees released. The Anderson opinion becomes the leading judicial documentation of what the operation looked like from inside the courtrooms.
- May 1, 1920Palmer’s predicted May Day revolution does not happen.
Palmer had publicly predicted a nationwide May Day 1920 revolutionary uprising. Cities went to full mobilization; the National Guard stood on alert; New York police were placed on twenty-four-hour duty. Nothing happened. The prediction’s failure — combined with the Post deportation reversals and the Anderson ruling — ends Palmer’s political career. He fails in his 1920 Democratic presidential bid.
- 1921 – 1924Hoover keeps the card file. The GID becomes the model.
Palmer leaves office in March 1921. Hoover remains at the Bureau. On December 10, 1924, Attorney General Harlan F. Stone appoints Hoover Director of the Bureau of Investigation, at twenty-nine years old, with a Stone-authored directive that the Bureau will no longer conduct political-belief investigations. Hoover ignores the directive within a year; the GID card file continues.
- April 1975 – April 1976The Church Committee traces the modern FBI political-intelligence apparatus back to the GID.
Book III of the Senate Select Committee’s final report, “Supplementary Detailed Staff Reports on Intelligence Activities and the Rights of Americans,” explicitly locates the origin of the FBI’s domestic-intelligence function in Palmer’s 1919 GID. The Church Committee treats the 1919 office and COINTELPRO (1956–71) as points on the same fifty-year continuum.
- November 1976The DOJ’s own Inspector General publishes the Levi Guidelines review.
Attorney General Edward H. Levi issues formal guidelines restricting FBI domestic-intelligence investigations. The accompanying OIG historical review, which is still on the DOJ’s own site, explicitly names the Palmer Raids as the foundational case of the exact abuses the guidelines are designed to prevent. This is the Justice Department, in its own voice, describing what its predecessors did in 1919 and 1920.
The Attorney General who signed it, the twenty-four-year-old who ran it, the officials who stopped it, and the lawyers who wrote it down.
Ordered by the date each subject first enters the record on this page.
Status: Bureau of Investigation Director from Dec 10, 1924. FBI Director until his death on May 2, 1972.
Twenty-four years old when appointed to lead the GID in 1919. Built and personally maintained the 200,000-name card file. The direct organizational continuity from the Palmer Raids through COINTELPRO runs through him. Hoover did not view the 1919 operation as a mistake; he cited it repeatedly across his fifty-three-year FBI directorship as vindication of an aggressive posture toward domestic radicalism.
Status: Left office March 4, 1921. Failed 1920 presidential bid. Died May 11, 1936.
A Quaker congressman-turned-Attorney-General who ran the operation the office is named for. His June 1919 house bombing appears to have shifted him permanently on domestic radicalism. His November 14, 1919 Senate report is the primary source that names the GID, names the Union of Russian Workers, and defends the methodology. Palmer’s political career ended with the failure of his May 1920 revolution prediction.
Status: Died in Toronto, May 14, 1940.
One of 249 passengers aboard the USAT Buford — the ‘Soviet Ark’ — on December 21, 1919. Goldman had lost her U.S. citizenship earlier the same year on the theory that her marriage to a naturalized citizen had been fraudulent. Her deportation was among the highest-profile individual outcomes of the operation.
Status: Retired March 4, 1921.
Post is the reason the raids did not produce ten thousand deportations. Reviewing each of roughly 6,000 pending deportation warrants individually against the actual evidentiary standard of the Immigration Act, he cancelled the vast majority. Palmer demanded his impeachment; the House Rules Committee, after hearings, declined to recommend it. Post was later described by Frankfurter as one of the most important individual defenders of civil liberties in that decade.
Status: Appointed to the U.S. Supreme Court, January 30, 1939. Died February 22, 1965.
Frankfurter’s presence on the Twelve Lawyers Report matters because it made the report impossible to dismiss as politically radical. He was a future Supreme Court Justice, a Harvard Law School professor, and a former Assistant Secretary of Labor himself. The report he co-signed remains the most detailed contemporary judicial-quality documentation of Bureau conduct during the raids.
Status: Retired as Dean in 1936. Died July 1, 1964.
The sitting Dean of Harvard Law School co-signed the document that accused the U.S. Department of Justice, in its own name, of “illegal practices.” Pound’s participation is the load-bearing academic-establishment endorsement of the report’s findings.
Status: Retired 1926. Died December 4, 1938.
Author of the leading federal judicial repudiation of the Palmer methodology in Colyer v. Skeffington (1920). Anderson’s opinion, calling the Bureau’s conduct “shocking to conscience,” became one of the operative citations in later civil-liberties jurisprudence. Reviewing the Boston-area January 1920 arrests, he ordered detainees released and documented specific tactics in judicial findings of fact.
Status: Named Hoover Director of the Bureau of Investigation on December 10, 1924. Sworn in as Chief Justice July 3, 1941.
Stone is the pivot figure of the aftermath. His formal directive on appointing Hoover explicitly barred the Bureau from conducting investigations based on political belief. The card file continued under Hoover’s stewardship regardless. Stone’s later career on the Supreme Court, culminating in his Chief Justiceship, made him the highest-ranking legal official ever to have publicly repudiated the Palmer-era methodology in writing.
Twelve claims about the Palmer Raids, each graded against the paper trail, ordered by the date of the fact each claim asserts.
Ordered chronologically. Each claim is anchored to a primary source already cited in §3 Timeline or §10 Sources.
- Claim 1 · August 1, 1919FACT
Attorney General A. Mitchell Palmer created the General Intelligence Division inside the Bureau of Investigation and appointed twenty-four-year-old J. Edgar Hoover to lead it.
Basis: Palmer's own November 14, 1919 report to the Senate names the GID and identifies its mission. Selden (op cit.) reconstructs the appointment. DOJ OIG (1976) confirms the organizational history in the department's own institutional record.
- Claim 2 · November 7, 1919FACT
Bureau of Investigation agents, working with local police, conducted mass arrests of Union of Russian Workers members in at least twelve U.S. cities.
Basis: Palmer's Senate report of November 14, 1919 describes the operation. The 1920 Twelve Lawyers Report documents specific cases in New York, Detroit, and elsewhere with names and file citations. Federal District Judge Anderson's June 1920 opinion in Colyer v. Skeffington documents parallel facts in Boston.
- Claim 3 · November 7, 1919FACT
The raid on the Russian People's House at 133 East 15th Street, New York, involved forced entry without warrants and use of physical force against detainees on the premises.
Basis: Documented in the Twelve Lawyers Report of May 28, 1920 (specific case files) and reprised in the DOJ OIG's 1976 Levi Guidelines historical review.
- Claim 4 · December 21, 1919FACT
The USAT Buford sailed from New York with 249 deportees to Soviet Russia; most had not received individual immigration hearings before deportation.
Basis: Contemporary press coverage; the National Archives holds the underlying deportation records in Record Group 60 (General Records of the Department of Justice). The Post Rules-Committee testimony of 1920 documented the procedural gaps.
- Claim 5 · January 2, 1920FACT
Between three thousand and ten thousand people were arrested in coordinated Bureau of Investigation raids across more than thirty U.S. cities in a single night.
Basis: Palmer's own Rules Committee testimony in 1920 acknowledged approximately 3,000 arrests. Contemporary press estimates ran to 10,000. The 1976 DOJ OIG review settles on 'at least 3,000' as the department's own conservative estimate.
- Claim 6 · January 2, 1920FACT
A substantial fraction of the January 1920 arrests were conducted without individual warrants for the specific persons arrested.
Basis: Judge Anderson's finding of fact in Colyer v. Skeffington (June 1, 1920) documents warrantless arrest in the Boston operation. The Twelve Lawyers Report documents warrantless arrest across multiple cities. Palmer's own subsequent testimony conceded that agents relied on 'blanket' administrative warrants for classes of persons, which Anderson ruled unconstitutional as applied.
- Claim 7 · May 28, 1920FACT
Twelve prominent American lawyers — including future Supreme Court Justice Felix Frankfurter and Harvard Law Dean Roscoe Pound — signed a report accusing the U.S. Department of Justice of illegal practices during the raids.
Basis: The Report Upon the Illegal Practices of the United States Department of Justice was published on May 28, 1920 and remains in print in facsimile via the National Popular Government League archive. All twelve signatories are documented.
- Claim 8 · May 1920FACT
Assistant Secretary of Labor Louis F. Post personally cancelled roughly 1,500 of the pending deportation warrants after individual review.
Basis: Post's own testimony before the House Rules Committee, 1920, documented the cancellations. Contemporary DOL records and later academic reconstruction (Post's own memoir, published 1923) corroborate the count.
- Claim 9 · June 1, 1920FACT
Federal District Judge George W. Anderson ruled that the Bureau's conduct in the Boston raid was unconstitutional and ordered detainees released.
Basis: Colyer v. Skeffington, 265 F. 17 (D. Mass. 1920). The opinion is in the Federal Reporter and remains binding precedent within the District of Massachusetts.
- Claim 10 · 1921FACT
By 1921, the General Intelligence Division's card file on domestic radicals contained roughly 200,000 names.
Basis: Selden (op cit.) reconstructs the file's scale from Bureau internal records; the DOJ OIG's 1976 review confirms the order of magnitude.
- Claim 11 · 1924 onwardPROBABLY TRUE
Hoover continued to maintain the political-radical card file after Attorney General Harlan F. Stone's December 10, 1924 directive expressly barred such investigations.
Basis: The Stone directive is documented in DOJ records. Continued Bureau political-intelligence activity through the 1920s and 1930s is documented in the Church Committee's Book III (1976) and in Athan Theoharis's archival work. Direct linkage from the 1919 card file to specific later files is inferable but not itemized in a single primary document; hence PROBABLY_TRUE rather than FACT.
- Claim 12 · April 1976FACT
The Church Committee's final report explicitly identified the 1919 General Intelligence Division as the origin of the FBI's domestic-intelligence function that COINTELPRO later extended.
Basis: Senate Select Committee to Study Governmental Operations, Final Report, Book III (1976), Supplementary Detailed Staff Reports on Intelligence Activities and the Rights of Americans. The lineage is stated in the committee's own text.
What the record settles about the Palmer Raids, and what it leaves open for good reason.
Ordered by the date of the fact each entry addresses. Where the record supports a claim, we say so. Where it does not, we say that too.
Whether the mail-bomb campaign was foreign-directed, domestically-organized, or the work of a small isolated cell.
The record does not settle this. Carlo Valdinoci, killed by his own bomb at Palmer's Washington house on June 2, 1919, was identified as an Italian anarchist connected to the Luigi Galleani circle. Beyond the Galleanist attribution, the operational scale and coordination of the campaign remain historically contested. What is FACT is that the bombings happened and that they preceded Palmer's operational shift.
Grading: PROBABLY_TRUE (Galleanist attribution); PURE_SPECULATION (state-sponsored foreign direction)
Whether Hoover personally directed operational decisions in the raids, or served principally as intelligence analyst supporting Bureau agents in the field.
Selden (op cit.) argues Hoover's operational role was substantial. Athan Theoharis's later archival work broadly supports this. Palmer's own Senate report of November 14, 1919 attributes the intelligence work to the GID (i.e., to Hoover) but ascribes operational execution to Bureau field offices. The record supports Hoover-as-architect-of-the-target-lists; it does not fully settle Hoover-as-operational-commander.
Grading: PROBABLY_TRUE for the architect role; less clear for direct operational command
The precise arrest and deportation counts.
Arrest counts range from Palmer's own 'approximately 3,000' to contemporary press estimates of 10,000. Deportation counts are firmer: the DOJ OIG's 1976 review cites 'roughly 556' deportations completed from the arrests. Post's cancellation of ~1,500 warrants explains most of the gap between arrested and deported. Different scholars use different endpoints (November 1919 only, January 1920 only, both combined) and different geographical scopes.
Grading: FACT that mass arrests happened; FACT that at least 556 were deported; PROBABLY_TRUE on the higher-end arrest count of 6,000–10,000
Whether detainees at the Russian People's House and comparable facilities were subjected to conduct meeting a contemporary legal definition of torture.
The Twelve Lawyers Report documents specific instances of physical mistreatment, prolonged incommunicado detention, denial of counsel, and deprivation of food and sleep. Judge Anderson's opinion in Colyer v. Skeffington makes judicial findings on similar treatment in the Boston operation. Whether these facts constitute 'torture' under the standards in force in 1919 versus contemporary international-humanitarian-law standards is a definitional question the record cannot settle. The underlying acts are FACT.
Grading: FACT for the specific acts; the labeling is definitional
Whether the USAT Buford deportees were meaningfully processed as individuals rather than in bulk.
Individual deportation warrants were issued for the 249 passengers. Whether they received substantive individual hearings on the merits is a separate question and was the specific complaint Louis Post raised months later, which led to his cancellation of subsequent deportation orders in the January 1920 batch. Goldman's own account (published 1931 in Living My Life) documents the procedural bypass in her case.
Grading: FACT that formal warrants existed; FACT that substantive individual hearings largely did not
Whether the continued existence of the GID card file after the 1920 political reversal constituted a defiance of Congressional or executive intent, or the ordinary continuation of a lawfully-created office.
The GID was not formally abolished. Attorney General Stone's 1924 directive against political-belief investigations was internal DOJ policy, not statute. The Church Committee's 1976 Book III treats the continuation as functionally defiant of the political reversal that ended the raids; the DOJ OIG's 1976 review is more institutionally cautious in its framing. Both agree the card file continued.
Grading: FACT that the file continued; contested how to characterize its legal status through the 1920s
The Palmer Raids are Hub 9’s pre-history because the tactic Hoover invented in 1919 ran, in an unbroken office, until at least 1971.
The Sowing Division hub argues that manufacturing division to fracture citizen movements has been federal method for a hundred and seven years. The Palmer Raids are the pre-history that makes the “COINTELPRO was a 1960s aberration” framing impossible to sustain. Hoover was in the same office in 1919 that he ran in 1971. The 1919 card file logic — sort populations by perceived political loyalty, keep the sort updated, target the sort administratively rather than by prosecution — is the exact logic of COINTELPRO’s five sub-programs.
The 1976 Levi Guidelines review is the most damning single document in the entire lineage, because it is the DOJ itself saying so. When the department’s own Inspector General reaches back fifty-seven years to identify the abuses that new guidelines are meant to prevent, the department is documenting its own institutional memory of what it did. That review is why this investigation, even in 2026, is not revisionist history: it is re-reading the record the department wrote about itself.
The Palmer Raids created the office, the card file, and the method that COINTELPRO would run at scale thirty-seven years later — and the man who built all three kept his job for fifty-three years.
Questions worth taking seriously
Are the Palmer Raids just an early episode of federal overreach, or something structurally different?
Is it fair to call this the birth of the FBI’s political-policing role?
How did the operation end — was there ever a formal reckoning?
Why does the piece grade the Galleanist attribution of the mail bombs only as PROBABLY_TRUE?
Does the piece treat J. Edgar Hoover’s later career as an argument about the 1919 record?
