Suppressed History: What They Don't Teach in School (And Why)

Every country teaches a version of its own history. The version taught in schools is selected, compressed, and shaped by whoever controls the curriculum. That is not a conspiracy. It is a structural feature of public education. The question is which facts end up outside the frame, and whether that exclusion is accidental or deliberate.

In the United States, certain events are documented in government records, congressional testimony, and court proceedings but remain absent from most K-12 curricula. Here are some of them.

The Tulsa Race Massacre (1921)

On the night of May 31 and into June 1, 1921, a white mob destroyed the Greenwood District of Tulsa, Oklahoma, a prosperous Black neighborhood known nationally as "Black Wall Street." They burned 35 city blocks, destroyed 1,256 homes, and killed somewhere between 100 and 300 people. The exact death toll was never established because the massacre was not officially investigated for nearly 80 years.

The Oklahoma state government commissioned its first official investigation in 1997. The final report, released in 2001, confirmed the scale of the destruction and noted that reparations had never been paid to survivors or their descendants. The Tulsa Race Massacre was not included in Oklahoma school curricula until after 2020.

The suppression was not accidental. Local newspapers that had covered the massacre in 1921 were bought up, archives were reportedly destroyed, and survivors were discouraged from speaking publicly. The most prosperous Black community in the country was destroyed in less than 16 hours, and the official response was to pretend it had not happened.

MKULTRA: The CIA's Mind Control Program

From 1953 to 1973, the CIA ran a classified program called MKULTRA that tested the effects of drugs, hypnosis, electroconvulsive therapy, and psychological manipulation on human subjects, often without their knowledge or consent. The program experimented on mental patients, prisoners, drug addicts, and sex workers. It also experimented on civilians who had no idea they were test subjects.

Frank Olson, a U.S. Army scientist, was dosed with LSD without his knowledge in 1953. Nine days later he fell from a 13th-floor hotel window in New York. His death was ruled a suicide. In 1994, his body was exhumed and a forensic pathologist found evidence of a blow to the head before the fall. No one was prosecuted.

MKULTRA was exposed in 1977 during Senate hearings led by Senator Frank Church. CIA Director Stansfield Turner confirmed the program's existence. The bulk of MKULTRA records had been ordered destroyed by CIA Director Richard Helms in 1973, when he learned of the impending congressional investigation. This is in the congressional record. It is not a conspiracy theory.

Operation Mockingbird: Media and the CIA

The Church Committee investigations of 1975 to 1976 also revealed that the CIA had, for decades, maintained relationships with American journalists, news organizations, and book publishers. Carl Bernstein, one of the Watergate reporters, published a 25,000-word investigation of this in Rolling Stone in 1977, naming over 400 journalists who had worked with the CIA in some capacity. The named organizations included The New York Times, CBS, Time magazine, and Newsweek.

The Business Plot (1933)

In 1933, Marine Corps Major General Smedley Butler, one of the most decorated soldiers in American history, testified before a congressional committee that a group of wealthy businessmen had approached him to lead a military coup against President Franklin D. Roosevelt. The plan, according to Butler, was to use 500,000 veterans to march on Washington and install a fascist government modeled on Mussolini's Italy.

The congressional committee investigating the claim confirmed that "certain persons had made an attempt to establish a fascist organization in this country." No one was ever prosecuted. Butler's testimony is in the congressional record.

The Indian Boarding School System

From the 1870s through the 1970s, the U.S. government removed Indigenous children from their families and placed them in federally funded boarding schools operated under the explicit policy of cultural erasure. The phrase used by the schools' founder, Richard Henry Pratt, was "kill the Indian, save the man." Physical and sexual abuse was widespread.

The U.S. Department of the Interior published its Federal Indian Boarding School Initiative Investigative Report in May 2022. It identified 408 federally operated or supported boarding schools and confirmed that children died at many of them. The total death toll is unknown because burial records were deliberately destroyed or never kept.

The Pattern Behind the Omissions

These are not random gaps. The events excluded from standard American history education share a common feature: they involve the U.S. government or powerful American institutions committing documented crimes against their own citizens or against vulnerable populations. Teaching them fully would require a more complicated national self-image than the one most curricula aim to produce.

That is not a cynical observation. It is a structural one. Every country does it. Understanding that it happens is the beginning of doing something about it.

The Hidden History of America: Forgotten Betrayals and Suppressed Truths covers these events and others with primary source documentation. The history is not comfortable. It is also not secret, which is precisely what makes its continued absence from mainstream education so telling.
